Documentation

Welcome to the documentation of Computer Vision Annotation Tool.

CVAT is a free, online, interactive video and image annotation tool for computer vision. It is being developed and used by Intel to annotate millions of objects with different properties. Many UI and UX decisions are based on feedbacks from professional data annotation team. Try it online app.cvat.ai.

Our documentation provides information for AI researchers, system administrators, developers, simple and advanced users. The documentation is divided into three sections, and each section is divided into subsections basic and advanced.

You need to upload images or videos for your future annotation. To do so, simply drag and drop the files.

To learn more, go to creating an annotation task

Annotation

Basic

When the task is created, you will see a corresponding message in the top right corner. Click the Open task button to go to the task page.

Once on the task page, open a link to the job in the jobs list.

Choose a correct section for your type of the task and start annotation.

Shape Annotation Interpolation
Rectangle Shape mode (basics) Track mode (basics)
Polygon Annotation with polygons Track mode with polygons
Polyline Annotation with polylines
Points Points in shape mode Liner interpolation with one point
Cuboids Annotation with cuboids Editing the cuboid
Tag Annotation with tags

Advanced

In CVAT there is the possibility of using automatic and semi-automatic annotation what gives you the opportunity to speed up the execution of the annotation:

Export dataset

This section contains documents for CVAT simple and advanced users

2.1 - Basics

This section contains basic documents for CVAT users

2.1.1 - Authorization

  • First of all, you have to log in to CVAT tool.

  • For register a new user press “Create an account”

  • You can register a user but by default it will not have rights even to view list of tasks. Thus you should create a superuser. The superuser can use Django administration panel to assign correct groups to the user. Please use the command below to create an admin account:

      docker exec -it cvat_server bash -ic 'python3 ~/manage.py createsuperuser'
    
  • If you want to create a non-admin account, you can do that using the link below on the login page. Don’t forget to modify permissions for the new user in the administration panel. There are several groups (aka roles): admin, user, annotator, observer.

Administration panel

Go to the Django administration panel. There you can:

  • Create / edit / delete users

  • Control permissions of users and access to the tool.

2.1.2 - Creating an annotation task

Instructions on how to create and configure an annotation task.

Create an annotation task pressing + button and select Create new task on the tasks page or on the project page.

Notice that the task will be created in the organization that you selected at the time of creation. Read more about organizations.

Specify parameters of the task:

Basic configuration

Name

The name of the task to be created.

Projects

The project that this task will be related with.

Labels

There are two ways of working with labels (available only if the task is not related to the project):

  • The Constructor is a simple way to add and adjust labels. To add a new label click the Add label button.

    You can set a name of the label in the Label name field and choose a color for each label.

    If necessary you can add an attribute and set its properties by clicking Add an attribute:

    The following actions are available here:

    1. Set the attribute’s name.
    2. Choose the way to display the attribute:
      • Select — drop down list of value
      • Radio — is used when it is necessary to choose just one option out of few suggested.
      • Checkbox — is used when it is necessary to choose any number of options out of suggested.
      • Text — is used when an attribute is entered as a text.
      • Number — is used when an attribute is entered as a number.
    3. Set values for the attribute. The values could be separated by pressing Enter. The entered value is displayed as a separate element which could be deleted by pressing Backspace or clicking the close button (x). If the specified way of displaying the attribute is Text or Number, the entered value will be displayed as text by default (e.g. you can specify the text format).
    4. Checkbox Mutable determines if an attribute would be changed frame to frame.
    5. You can delete the attribute by clicking the close button (x).

    Click the Continue button to add more labels. If you need to cancel adding a label - press the Cancel button. After all the necessary labels are added click the Done button. After clicking Done the added labels would be displayed as separate elements of different colour. You can edit or delete labels by clicking Update attributes or Delete label.

  • The Raw is a way of working with labels for an advanced user. Raw presents label data in json format with an option of editing and copying labels as a text. The Done button applies the changes and the Reset button cancels the changes.

Select files

Press tab My computer to choose some files for annotation from your PC. If you select tab Connected file share you can choose files for annotation from your network. If you select Remote source , you’ll see a field where you can enter a list of URLs (one URL per line). If you upload a video or dataset with images and select Use cache option, you can attach a manifest.jsonl file. You can find how to prepare it here. If you select the Cloud Storage tab, you can select a cloud storage (for this type the cloud storage name), after that choose the manifest file and select the required files. For more information on how to attach cloud storage, see attach cloud storage

Data formats for a 3D task

To create a 3D task, you must prepare an archive with one of the following directory structures:

    VELODYNE FORMAT
    Structure:
      velodyne_points/
        data/
          image_01.bin
          IMAGE_00 # unknown dirname,
                   # generally image_01.png can be under IMAGE_00, IMAGE_01, IMAGE_02, IMAGE_03, etc
      data/
        image_01.png
  
    3D POINTCLOUD DATA FORMAT
    Structure:
      pointcloud/
        00001.pcd
      related_images/
        00001_pcd/
          image_01.png # or any other image
  
    3D, DEFAULT DATAFORMAT Option 1
    Structure:
      data/
        image.pcd
        image.png
  
    3D, DEFAULT DATAFORMAT Option 2
    Structure:
      data/
        image_1/
            image_1.pcd
            context_1.png # or any other name
            context_2.jpg
  

You can’t mix 2D and 3D data in the same task.

Advanced configuration

Sorting method

Option to sort the data. It is not relevant for videos. For example, the sequence 2.jpeg, 10.jpeg, 1.jpeg after sorting will be:

  • lexicographical: 1.jpeg, 10.jpeg, 2.jpeg
  • natural: 1.jpeg, 2.jpeg, 10.jpeg
  • predefined: 2.jpeg, 10.jpeg, 1.jpeg

Use zip/video chunks

Force to use zip chunks as compressed data. Cut out content for videos only.

Use cache

Defines how to work with data. Select the checkbox to switch to the “on-the-fly data processing”, which will reduce the task creation time (by preparing chunks when requests are received) and store data in a cache of limited size with a policy of evicting less popular items. See more here.

Image Quality

Use this option to specify quality of uploaded images. The option helps to load high resolution datasets faster. Use the value from 5 (almost completely compressed images) to 100 (not compressed images).

Overlap Size

Use this option to make overlapped segments. The option makes tracks continuous from one segment into another. Use it for interpolation mode. There are several options for using the parameter:

  • For an interpolation task (video sequence). If you annotate a bounding box on two adjacent segments they will be merged into one bounding box. If overlap equals to zero or annotation is poor on adjacent segments inside a dumped annotation file, you will have several tracks, one for each segment, which corresponds to the object.
  • For an annotation task (independent images). If an object exists on overlapped segments, the overlap is greater than zero and the annotation is good enough on adjacent segments, it will be automatically merged into one object. If overlap equals to zero or annotation is poor on adjacent segments inside a dumped annotation file, you will have several bounding boxes for the same object. Thus, you annotate an object on the first segment. You annotate the same object on second segment, and if you do it right, you will have one track inside the annotations. If annotations on different segments (on overlapped frames) are very different, you will have two shapes for the same object. This functionality works only for bounding boxes. Polygons, polylines, points don’t support automatic merge on overlapped segments even the overlap parameter isn’t zero and match between corresponding shapes on adjacent segments is perfect.

Segment size

Use this option to divide a huge dataset into a few smaller segments. For example, one job cannot be annotated by several labelers (it isn’t supported). Thus using “segment size” you can create several jobs for the same annotation task. It will help you to parallel data annotation process.

Start frame

Frame from which video in task begins.

Stop frame

Frame on which video in task ends.

Frame Step

Use this option to filter video frames. For example, enter 25 to leave every twenty fifth frame in the video or every twenty fifth image.

Chunk size

Defines a number of frames to be packed in a chunk when send from client to server. Server defines automatically if empty.

Recommended values:

  • 1080p or less: 36
  • 2k or less: 8 - 16
  • 4k or less: 4 - 8
  • More: 1 - 4

Dataset Repository

URL link of the repository optionally specifies the path to the repository for storage (default: annotation / <dump_file_name> .zip). The .zip and .xml file extension of annotation are supported. Field format: URL [PATH] example: https://github.com/project/repos.git [1/2/3/4/annotation.xml]

Supported URL formats :

  • https://github.com/project/repos[.git]
  • github.com/project/repos[.git]
  • git@github.com:project/repos[.git]

After the task is created, the synchronization status is displayed on the task page.

If you specify a dataset repository, when you create a task, you will see a message about the need to grant access with the ssh key. This is the key you need to add to your github account. For other git systems, you can learn about adding an ssh key in their documentation.

Use LFS

If the annotation file is large, you can create a repository with LFS support.

Issue tracker

Specify full issue tracker’s URL if it’s necessary.

To save and open task click on Submit & Open button. Also you can click on Submit & Continue button for creating several tasks in sequence. Then, the created tasks will be displayed on a tasks page.

2.1.3 - Jobs page

On the jobs page, users (for example, with the worker role) can see the jobs that are assigned to them without having access to the task page, as well as track progress, sort and apply filters to the job list.

On the job page there is a list of jobs presented in the form of tiles, where each tile is one job. Each element contains:

  • job ID
  • dimension 2D or 3D
  • preview
  • stage and state
  • when hovering over an element, you can see:
    • size
    • assignee
  • menu to navigate to a task, project, or bug tracker.

To open the job in a new tab, click on the job by holding Ctrl.

In the upper left corner there is a search bar, using which you can find the job by assignee, stage, state, etc. In the upper right corner there are sorting, quick filters and filter.

Filter

Applying filter disables the quick filter.

The filter works similarly to the filters for annotation, you can create rules from properties, operators and values and group rules into groups. For more details, see the filter section. Learn more about date and time selection.

For clear all filters press Clear filters.

2.1.5 - Task details

Overview of the Task details page.

Task details is a task page which contains a preview, a progress bar and the details of the task (specified when the task was created) and the jobs section.

  • The next actions are available on this page:

    1. Change the task’s title.

    2. Open Actions menu.

    3. Change issue tracker or open issue tracker if it is specified.

    4. Change labels (available only if the task is not related to the project). You can add new labels or add attributes for the existing labels in the Raw mode or the Constructor mode. By clicking Copy you will copy the labels to the clipboard.

    5. Assigned to — is used to assign a task to a person. Start typing an assignee’s name and/or choose the right person out of the dropdown list. In the list of users, you will only see the users of the organization where the task is created.

    6. Dataset Repository

      • Repository link
      • Synchronization status with dataset repository. When you click on the status, the current annotation will be sent. It has several states:
        • Synchronized - task synchronized, that is, created a pull of requisites with an actual annotation file.
        • Merged - merged pull request with up-to-date annotation file.
        • Synchronize - highlighted in red, annotations are not synced.
      • Use a format drop-down list of formats in which the annotation can be synchronized.
      • Support for large file enabling the use of LFS.
  • Jobs — is a list of all jobs for a particular task. Here you can find the next data:

    • Jobs name with a hyperlink to it.
    • Frames — the frame interval.
    • A stage of the job. The stage is specified by a drop-down list. There are three stages: annotation, validation or acceptance. This value affects the task progress bar.
    • A state of the job. The state can be changed by an assigned user in the menu inside the job. There are several possible states: new, in progress, rejected, completed.
    • Started on — start date of this job.
    • Duration — is the amount of time the job is being worked.
    • Assignee is the user who is working on the job. You can start typing an assignee’s name and/or choose the right person out of the dropdown list.
    • Reviewer – a user assigned to carry out the review, read more in the review section.
    • Copy. By clicking Copy you will copy the job list to the clipboard. The job list contains direct links to jobs.

    You can filter or sort jobs by status, as well as by assigner or reviewer.

Follow a link inside Jobs section to start annotation process. In some cases, you can have several links. It depends on size of your task and Overlap Size and Segment Size parameters. To improve UX, only the first chunk of several frames will be loaded and you will be able to annotate first images. Other frames will be loaded in background.

2.1.6 - Interface of the annotation tool

Main user interface

The tool consists of:

  • Header - pinned header used to navigate CVAT sections and account settings;

  • Top panel — contains navigation buttons, main functions and menu access;

  • Workspace — space where images are shown;

  • Controls sidebar — contains tools for navigating the image, zoom, creating shapes and editing tracks (merge, split, group);

  • Objects sidebar — contains label filter, two lists: objects (on the frame) and labels (of objects on the frame) and appearance settings.

Pop-up messages

Pop-up message

In CVAT, you’ll receive pop-up messages in the upper-right corner, on any page. Pop-up messages can contain useful information, links, or error messages.

Information message

Informational messages inform about the end of the auto-annotation process. Learn more about auto-annotation.

Jump Suggestion Messages

Open a task

After creating a task, you can immediately open it by clicking Open task. Learn more about creating a task.

Continue to the frame on which the work on the job is finished

When you open a job that you previously worked on, you will receive pop-up messages with a proposal to go to the frame that was visited before closing the tab.

Error Messages

If you perform impossible actions, you may receive an error message. The message may contain information about the error or a prompt to open the browser console (shortcut F12) for information. If you encounter a bug that you can’t solve yourself, you can create an issue on GitHub.

2.1.7 - Basic navigation

Overview of basic controls.
  1. Use arrows below to move to the next/previous frame. Use the scroll bar slider to scroll through frames. Almost every button has a shortcut. To get a hint about a shortcut, just move your mouse pointer over an UI element.

  2. To navigate the image, use the button on the controls sidebar. Another way an image can be moved/shifted is by holding the left mouse button inside an area without annotated objects. If the Mouse Wheel is pressed, then all annotated objects are ignored. Otherwise the a highlighted bounding box will be moved instead of the image itself.

  3. You can use the button on the sidebar controls to zoom on a region of interest. Use the button Fit the image to fit the image in the workspace. You can also use the mouse wheel to scale the image (the image will be zoomed relatively to your current cursor position).

2.1.8 - Top Panel

Overview of controls available on the top panel of the annotation tool.


It is the main menu of the annotation tool. It can be used to download, upload and remove annotations.

Button assignment:

  • Upload Annotations — uploads annotations into a task.

  • Export as a dataset — download a data set from a task in one of the supported formats. You can also enter a Custom name and enable the Save images checkbox if you want the dataset to contain images.

  • Remove Annotations — calls the confirmation window if you click Delete, the annotation of the current job will be removed, if you click Select range you can remove annotation on range frames, if you activate checkbox Delete only keyframe for tracks then only keyframes will be deleted from the tracks, on the selected range.

  • Open the task — opens a page with details about the task.

  • Change job state - changes the state of the job (new, in progress, rejected, completed).

  • Finish the job/Renew the job - changes the job stage and state to acceptance and completed / annotation and new correspondingly.

Save Work

Saves annotations for the current job. The button has an indication of the saving process.

Undo-redo buttons

Use buttons to undo actions or redo them.


Done

Used to complete the creation of the object. This button appears only when the object is being created.

2.1.10 - Objects sidebar

Overview of available functions on the objects sidebar of the annotation tool.

Hide objects sidebar

Hide - the button hides the object’s sidebar.

Objects

Filter input box

The way how to use filters is described in the advanced guide here.

List of objects

  • Switch lock property for all - switches lock property of all objects in the frame.
  • Switch hidden property for all - switches hide property of all objects in the frame.
  • Expand/collapse all - collapses/expands the details field of all objects in the frame.
  • Sorting - sort the list of objects: updated time, ID - accent, ID - descent

In the objects sidebar you can see the list of available objects on the current frame. The following figure is an example of how the list might look like:

Shape mode Track mode

Objects on the side bar

The type of a shape can be changed by selecting Label property. For instance, it can look like shown on the figure below:

Object action menu

The action menu calls up the button:

The action menu contains:

  • Create object URL - puts a link to an object on the clipboard. After you open the link, this object will be filtered.

  • Make a copy- copies an object. The keyboard shortcut is Ctrl + C Ctrl + V.

  • Propagate - Сopies the form to several frames, invokes a dialog box in which you can specify the number of copies or the frame onto which you want to copy the object. The keyboard shortcut Ctrl + B.

  • To background - moves the object to the background. The keyboard shortcut -,_.

  • To foreground - moves the object to the foreground. The keyboard shortcut +,=.

  • Change instance color- choosing a color using the color picker (available only in instance mode).

  • Remove - removes the object. The keyboard shortcut Del,Shift+Del.

A shape can be locked to prevent its modification or moving by an accident. Shortcut to lock an object: L.

A shape can be Occluded. Shortcut: Q. Such shapes have dashed boundaries.

You can change the way an object is displayed on a frame (show or hide).

Switch pinned property - when enabled, a shape cannot be moved by dragging or dropping.

Tracker switcher - enable/disable tracking for the object.

By clicking on the Details button you can collapse or expand the field with all the attributes of the object.


Labels

In this tab you can lock or hide objects of a certain label. To change the color for a specific label, you need to go to the task page and select the color by clicking the edit button, this way you will change the label color for all jobs in the task.

Fast label change

You can change the label of an object using hot keys. In order to do it, you need to assign a number (from 0 to 9) to labels. By default numbers 1,2…0 are assigned to the first ten labels. To assign a number, click on the button placed at the right of a label name on the sidebar.

After that you will be able to assign a corresponding label to an object by hovering your mouse cursor over it and pressing Ctrl + Num(0..9).

In case you do not point the cursor to the object, pressing Ctrl + Num(0..9) will set a chosen label as default, so that the next object you create (use N key) will automatically have this label assigned.


Appearance

Color By options

Change the color scheme of annotation:

  • Instance — every shape has random color

  • Group — every group of shape has its own random color, ungrouped shapes are white

  • Label — every label (e.g. car, person) has its own random color

    You can change any random color pointing to a needed box on a frame or on an object sidebar.

Fill Opacity slider

Change the opacity of every shape in the annotation.

Selected Fill Opacity slider

Change the opacity of the selected object’s fill. It is possible to change opacity while drawing an object in the case of rectangles, polygons and cuboids.

Outlines borders checkbox

You can change a special shape border color by clicking on the Eyedropper icon.

Show bitmap checkbox

If enabled all shapes are displayed in white and the background is black.

Show projections checkbox

Enables / disables the display of auxiliary perspective lines. Only relevant for cuboids

2.1.11 - Workspace

Overview of available functions on the workspace of the annotation tool.

This is the main field in which drawing and editing objects takes place. In addition the workspace also has the following functions:

  • Right-clicking on an object calls up the Object card - this is an element containing the necessary controls for changing the label and attributes of the object, as well as the action menu.

  • Right-clicking a point deletes it.

  • Z-axis slider - Allows you to switch annotation layers hiding the upper layers (slider is enabled if several z layers are on a frame). This element has a button for adding a new layer. When pressed, a new layer is added and switched to it. You can move objects in layers using the + and - keys.

If the related_images folder contains any images, a context image will be available in the perspective window. The contextual image could be compared to 3D data and would help to identify the labels of marked objects.

Perspective – a main window for work with objects in a 3D task.

Projections - projections are tied to an object so that a cuboid is in the center and looks like a rectangle. Projections show only the selected object.

  • Top – a projection of the view from above.
  • Side – a projection of the left side of the object.
  • Front - a frontal projection of the object.

2.1.13 - Standard 3D mode (basics)

Standard 3d mode - Designed to work with 3D data. The mode is automatically available if you add PCD or Kitty BIN format data when you create a task. read more

  • Points
  • Ellipse
  • Cuboid
  • Cuboid in 3d task
  • Skeleton
  • Tag

And there is how they all look like:

Tag - has no shape in the workspace, but is displayed in objects sidebar.

2.1.16 - Shape mode (basics)

Usage examples and basic operations available during annotation in shape mode.

Usage examples:

  • Create new annotations for a set of images.
  • Add/modify/delete objects for existing annotations.
  1. You need to select Rectangle on the controls sidebar:

    Before you start, select the correct Label (should be specified by you when creating the task) and Drawing Method (by 2 points or by 4 points):

  2. Creating a new annotation in Shape mode:

    • Create a separate Rectangle by clicking on Shape.

    • Choose the opposite points. Your first rectangle is ready!

    • To learn more about creating a rectangle read here.

    • It is possible to adjust boundaries and location of the rectangle using a mouse. Rectangle’s size is shown in the top right corner , you can check it by clicking on any point of the shape. You can also undo your actions using Ctrl+Z and redo them with Shift+Ctrl+Z or Ctrl+Y.

  3. You can see the Object card in the objects sidebar or open it by right-clicking on the object. You can change the attributes in the details section. You can perform basic operations or delete an object by clicking on the action menu button.

  4. The following figure is an example of a fully annotated frame with separate shapes.

    Read more in the section shape mode (advanced).

2.1.17 - Track mode (basics)

Usage examples and basic operations available during annotation in track mode.

Usage examples:

  • Create new annotations for a sequence of frames.
  • Add/modify/delete objects for existing annotations.
  • Edit tracks, merge several rectangles into one track.
  1. Like in the Shape mode, you need to select a Rectangle on the sidebar, in the appearing form, select the desired Label and the Drawing method.

  2. Creating a track for an object (look at the selected car as an example):

    • Create a Rectangle in Track mode by clicking on Track.

    • In Track mode the rectangle will be automatically interpolated on the next frames.

    • The cyclist starts moving on frame #2270. Let’s mark the frame as a key frame. You can press K for that or click the star button (see the screenshot below).

    • If the object starts to change its position, you need to modify the rectangle where it happens. It isn’t necessary to change the rectangle on each frame, simply update several keyframes and the frames between them will be interpolated automatically.

    • Let’s jump 30 frames forward and adjust the boundaries of the object. See an example below:

    • After that the rectangle of the object will be changed automatically on frames 2270 to 2300:

  3. When the annotated object disappears or becomes too small, you need to finish the track. You have to choose Outside Property, shortcut O.

  4. If the object isn’t visible on a couple of frames and then appears again, you can use the Merge feature to merge several individual tracks into one.

    • Create tracks for moments when the cyclist is visible:

    • Click Merge button or press key M and click on any rectangle of the first track and on any rectangle of the second track and so on:

    • Click Merge button or press M to apply changes.

    • The final annotated sequence of frames in Interpolation mode can look like the clip below:

      Read more in the section track mode (advanced).

2.1.18 - 3D Object annotation (basics)

2.1.20 - Vocabulary

List of terms pertaining to annotation in CVAT.

Label

Label is a type of an annotated object (e.g. person, car, vehicle, etc.)


Attribute

Attribute is a property of an annotated object (e.g. color, model, quality, etc.). There are two types of attributes:

Unique

Unique immutable and can’t be changed from frame to frame (e.g. age, gender, color, etc.)

Temporary

Temporary mutable and can be changed on any frame (e.g. quality, pose, truncated, etc.)


Track

Track is a set of shapes on different frames which corresponds to one object. Tracks are created in Track mode


Annotation

Annotation is a set of shapes and tracks. There are several types of annotations:

  • Manual which is created by a person
  • Semi-automatic which is created mainly automatically, but the user provides some data (e.g. interpolation)
  • Automatic which is created automatically without a person in the loop

Approximation

Approximation allows you to reduce the number of points in the polygon. Can be used to reduce the annotation file and to facilitate editing polygons.


Trackable

Trackable object will be tracked automatically if the previous frame was a latest keyframe for the object. More details in the section trackers.


Mode

Interpolation

Mode for video annotation, which uses track objects. Only objects on keyframes are manually annotation, and intermediate frames are linearly interpolated.

Related sections:

Annotation

Mode for images annotation, which uses shape objects.

Related sections:


Dimension

Depends on the task data type that is defined when the task is created.

2D

The data format of 2d tasks are images and videos. Related sections:

3D

The data format of 3d tasks is a cloud of points. Data formats for a 3D task

Related sections:


State

State of the job. The state can be changed by an assigned user in the menu inside the job. There are several possible states: new, in progress, rejected, completed.


Stage

Stage of the job. The stage is specified with the drop-down list on the task page. There are three stages: annotation, validation or acceptance. This value affects the task progress bar.


Subset

A project can have subsets. Subsets are groups for tasks that make it easier to work with the dataset. It could be test, train, validation or custom subset.


Credentials

Under credentials is understood Key & secret key, Account name and token, Anonymous access, Key file. Used to attach cloud storage.

2.1.22 - Attach cloud storage

Instructions on how to attach cloud storage using UI

In CVAT you can use AWS-S3, Azure Blob Container and Google cloud storages to store image datasets for your tasks.

Using AWS-S3

Create AWS account

First, you need to create an AWS account, to do this, register of 5 steps following the instructions (even if you plan to use a free basic account you may need to link a credit card to verify your identity).

To learn more about the operation and benefits of AWS cloud, take a free AWS Cloud Practitioner Essentials course, which will be available after registration.

Create a bucket

After the account is created, go to console AWS-S3 and click Create bucket.

You’ll be taken to the bucket creation page. Here you have to specify the name of the bucket, region, optionally you can copy the settings of another bucket by clicking on the choose bucket button. Checkbox block all public access can be enabled as we will use access key ID and secret access key to gain access. In the following sections, you can leave the default settings and click create bucket. After you create the bucket it will appear in the list of buckets.

Create user and configure permissions

To access bucket you will need to create a user, to do this, go IAM and click add users. You need to choose AWS access type, have an access key ID and secret access key.

After pressing next button to configure permissions, you need to create a user group. To do this click create a group, input the group name and select permission policies add AmazonS3ReadOnlyAccess using the search (if you want the user you create to have write rights to bucket select AmazonS3FullAccess).

You can also add tags for the user (optional), and look again at the entered data. In the last step of creating a user, you will be provided with access key ID and secret access key, they will need to be used in CVAT when adding cloud storage.

Upload dataset

Prepare dataset

For example, let’s take The Oxford-IIIT Pet Dataset:

  • Download the archive with images.

  • Unpack the archive into the prepared folder and create a manifest file as described in prepare manifest file section:

    python <cvat repository>/utils/dataset_manifest/create.py --output-dir <yourfolder> <yourfolder>
    

Upload

  • When the manifest file is ready, open the previously prepared bucket and click Upload:

  • Drag the manifest file and image folder on the page and click Upload:

Now you can attach new cloud storage into CVAT.

Using Azure Blob Container

Create Microsoft account

First, create a Microsoft account by registering, or you can use your GitHub account to log in. After signing up for Azure, you’ll need to choose a subscription plan, you can choose a free 12-month subscription, but you’ll need to enter your credit card details to verify your identity. To learn more about Azure, read documentation.

Create a storage account

After registration, go to Azure portal. Hover over the resource groups and click create in the window that appears.

Enter a name for the group and click review + create, check the entered data and click create. After the resource group is created, go to the resource groups page and navigate to the resource group that you created. Click create for create a storage account.

    Enter storage account name (will be used in CVAT to access your container), select a region, select performance in our case will be standard enough, select redundancy enough LRS more about redundancy. Click next to go to the advanced section.

  • Advanced

    In the advanced section, you can change public access by disabling enable blob public access to deny anonymous access to the container. If you want to change public access you can find this switch in the configuration section of your storage account.

    After that, go to the review section, check the entered data and click create.

You will be reached to the deployment page after the finished, navigate to the resource by clicking on go to resource.

Create a container

Go to the containers section and create a new container. Enter the name of the container (will be used in CVAT to access your container) and select container in public access level.

SAS token

Using the SAS token, you can securely transfer access to the container to other people by preconfiguring rights, as well as the date/time of the starting and expiration of the token. To generate a SAS token, go to Shared access signature section of your storage account. Here you should enable Blob in the Allowed services, Container and Object in the Allowed resource types, Read and List in the Allowed permissions, HTTPS and HTTP in the Allowed protocols, also here you can set the date/time of the starting and expiration for the token. Click Generation SAS token. and copy SAS token (will be used in CVAT to access your container).

For personal use, you can enter the Access Key from the your storage account in the SAS Token field, access key can be found in the security + networking section. Click show keys to show the key.

Upload dataset

Prepare the dataset as in the point prepare dataset.

  • When the dataset is ready, go to your container and click upload.

  • Click select a files and select all images from the images folder in the upload to folder item write the name of the folder in which you want to upload images in this case “images”.

  • Click upload, when the images are loaded you will need to upload a manifest file. When loading a manifest, you need to make sure that the relative paths specified in the manifest file match the paths to the files in the container. Click select a file and select manifest file, in order to upload file to the root of the container leave blank upload to folder field.

Now you can attach new cloud storage into CVAT.

Using Google Cloud Storage

Create Google account

First, create a Google account, go to account login page and click Create account. After, go to the Google Cloud page, click Get started, enter the required data and accept the terms of service (you’ll need credit card information to register).

      • Prefix - used to filter data from the bucket.

      • Project ID - you can find the created project on the cloud resource manager page, note that the project name does not match the project ID.

      • Location - here you can choose a region from the list or add a new one. To get more information click on ?.


  • Manifest - the path to the manifest file on your cloud storage. You can add multiple manifest files using the Add manifest button. You can find on how to prepare dataset manifest here. If you have data on the cloud storage and don’t want to download content locally, you can mount your cloud storage as a share point according to that guide and prepare manifest for the data.

To publish the cloud storage, click submit, after which it will be available on the Cloud storages page.

Using AWS Data Exchange

Subscribe to data set

You can use AWS Data Exchange to add image datasets. For example, consider adding a set of datasets 500 Image & Metadata Free Sample. Go to browse catalog and use the search to find 500 Image & Metadata Free Sample, open the dataset page and click continue to subscribe, you will be taken to the page complete subscription request, read the information provided and click send subscription request to provider.

Export to bucket

After that, this dataset will appear in the list subscriptions. Now you need to export the dataset to Amazon S3. First, let’s create a new one bucket similar to described above. To export one of the datasets to a new bucket open it entitled data select one of the datasets, select the corresponding revision and click export to Amazon S3 (please note that if bucket and dataset are located in different regions, export fees may apply). In the window that appears, select the created bucket and click export.

Prepare manifest file

Now you need to prepare a manifest file. I used AWS cli and script for prepare manifest file. Perform the installation using the manual aws-shell, I used aws-cli 1.20.49 Python 3.7.9 Windows 10. You can configure credentials by running aws configure. You will need to enter Access Key ID and Secret Access Key as well as region.

aws configure
Access Key ID: <your Access Key ID>
Secret Access Key: <your Secret Access Key>

Copy the content of the bucket to a folder on your computer:

aws s3 cp <s3://bucket-name> <yourfolder> --recursive

After copying the files, you can create a manifest file as described in preapair manifest file section:

python <cvat repository>/utils/dataset_manifest/create.py --output-dir <yourfolder> <yourfolder>

When the manifest file is ready, you can upload it to aws s3 bucket. If you gave full write permissions when you created the user, run:

aws s3 cp <yourfolder>/manifest.jsonl <s3://bucket-name>

If you have given read-only permissions, use the download through the browser, click upload, drag the manifest file to the page and click upload.

Now you can attach new cloud storage using the dataset 500 Image & Metadata Free Sample.

The member can leave the organization on his own by clicking Leave organization on the organization settings page.

Remove organization

You can remove an organization that you created. Deleting an organization will delete all related resources (annotations, jobs, tasks, projects, cloud storages, ..). In order to remove an organization, click Remove organization, you will be asked to confirm the deletion by entering the short name of the organization.

2.2.3 - Search

Overview of available search options.

There are several options how to use the search.

  • Search within all fields (owner, assignee, task name, task status, task mode). To execute enter a search string in search field.
  • Search for specific fields. How to perform:
    • owner: admin - all tasks created by the user who has the substring “admin” in his name
    • assignee: employee - all tasks which are assigned to a user who has the substring “employee” in his name
    • name: training - all tasks with the substring “training” in their names
    • mode: annotation or mode: interpolation - all tasks with images or videos.
    • status: annotation or status: validation or status: completed - search by status
    • id: 5 - task with id = 5.
  • Multiple filters. Filters can be combined (except for the identifier) ​​using the keyword AND:
    • mode: interpolation AND owner: admin
    • mode: annotation and status: annotation

The search is case insensitive.

2.2.4 - Shape mode (advanced)

Advanced operations available during annotation in shape mode.

Basic operations in the mode were described in section shape mode (basics).

Occluded Occlusion is an attribute used if an object is occluded by another object or isn’t fully visible on the frame. Use Q shortcut to set the property quickly.

Example: the three cars on the figure below should be labeled as occluded.

If a frame contains too many objects and it is difficult to annotate them due to many shapes placed mostly in the same place, it makes sense to lock them. Shapes for locked objects are transparent, and it is easy to annotate new objects. Besides, you can’t change previously annotated objects by accident. Shortcut: L.

2.2.5 - Track mode (advanced)

Advanced operations available during annotation in track mode.

Basic operations in the mode were described in section track mode (basics).

Shapes that were created in the track mode, have extra navigation buttons.

  • These buttons help to jump to the previous/next keyframe.

  • The button helps to jump to the initial frame and to the last keyframe.

You can use the Split function to split one track into two tracks:

2.2.6 - 3D Object annotation (advanced)

Overview of advanced operations available when annotating 3D objects.

As well as 2D-task objects, 3D-task objects support the ability to change appearance, attributes, properties and have an action menu. Read more in objects sidebar section.

Moving an object

If you hover the cursor over a cuboid and press Shift+N, the cuboid will be cut, so you can paste it in other place (double-click to paste the cuboid).

Copying

As well as in 2D task you can copy and paste objects by Ctrl+C and Ctrl+V, but unlike 2D tasks you have to place a copied object in a 3D space (double click to paste).

Image of the projection window

You can copy or save the projection-window image by left-clicking on it and selecting a “save image as” or “copy image”.

2.2.7 - Attribute annotation mode (advanced)

Advanced operations available in attribute annotation mode.

Basic operations in the mode were described in section attribute annotation mode (basics).

It is possible to handle lots of objects on the same frame in the mode.

It is more convenient to annotate objects of the same type. In this case you can apply the appropriate filter. For example, the following filter will hide all objects except person: label=="Person".

To navigate between objects (person in this case), use the following buttons switch between objects in the frame on the special panel:

or shortcuts:

  • Tab — go to the next object
  • Shift+Tab — go to the previous object.

In order to change the zoom level, go to settings (press F3) in the workspace tab and set the value Attribute annotation mode (AAM) zoom margin in px.

2.2.8 - Annotation with rectangles

To learn more about annotation using a rectangle, see the sections:

Rotation rectangle

To rotate the rectangle, pull on the rotation point. Rotation is done around the center of the rectangle. To rotate at a fixed angle (multiple of 15 degrees), hold shift. In the process of rotation, you can see the angle of rotation.

Annotation with rectangle by 4 points

It is an efficient method of bounding box annotation, proposed here. Before starting, you need to make sure that the drawing method by 4 points is selected.

Press Shape or Track for entering drawing mode. Click on four extreme points: the top, bottom, left- and right-most physical points on the object. Drawing will be automatically completed right after clicking the fourth point. Press Esc to cancel editing.

2.2.9 - Annotation with polygons

Guide to creating and editing polygons.

2.2.9.1 - Manual drawing

It is used for semantic / instance segmentation.

Before starting, you need to select Polygon on the controls sidebar and choose the correct Label.

  • Click Shape to enter drawing mode. There are two ways to draw a polygon: either create points by clicking or by dragging the mouse on the screen while holding Shift.
Clicking points Holding Shift+Dragging
  • When Shift isn’t pressed, you can zoom in/out (when scrolling the mouse wheel) and move (when clicking the mouse wheel and moving the mouse), you can also delete the previous point by right-clicking on it.
  • You can use the Selected opacity slider in the Objects sidebar to change the opacity of the polygon. You can read more in the Objects sidebar section.
  • Press N again or click the Done button on the top panel for completing the shape.
  • After creating the polygon, you can move the points or delete them by right-clicking and selecting Delete point or clicking with pressed Alt key in the context menu.

2.2.9.2 - Drawing using automatic borders

You can use auto borders when drawing a polygon. Using automatic borders allows you to automatically trace the outline of polygons existing in the annotation.

  • To do this, go to settings -> workspace tab and enable Automatic Bordering or press Ctrl while drawing a polygon.

  • Start drawing / editing a polygon.

  • Points of other shapes will be highlighted, which means that the polygon can be attached to them.

  • Define the part of the polygon path that you want to repeat.

  • Click on the first point of the contour part.

  • Then click on any point located on part of the path. The selected point will be highlighted in purple.

  • Click on the last point and the outline to this point will be built automatically.

Besides, you can set a fixed number of points in the Number of points field, then drawing will be stopped automatically. To enable dragging you should right-click inside the polygon and choose Switch pinned property.

Below you can see results with opacity and black stroke:

If you need to annotate small objects, increase Image Quality to 95 in Create task dialog for your convenience.

2.2.9.3 - Edit polygon

To edit a polygon you have to click on it while holding Shift, it will open the polygon editor.

  • In the editor you can create new points or delete part of a polygon by closing the line on another point.

  • When Intelligent polygon cropping option is activated in the settings, СVAT considers two criteria to decide which part of a polygon should be cut off during automatic editing.

    • The first criteria is a number of cut points.
    • The second criteria is a length of a cut curve.

    If both criteria recommend to cut the same part, algorithm works automatically, and if not, a user has to make the decision. If you want to choose manually which part of a polygon should be cut off, disable Intelligent polygon cropping in the settings. In this case after closing the polygon, you can select the part of the polygon you want to leave.

  • You can press Esc to cancel editing.

2.2.9.4 - Track mode with polygons

Polygons in the track mode allow you to mark moving objects more accurately other than using a rectangle (Tracking mode (basic); Tracking mode (advanced)).

  1. To create a polygon in the track mode, click the Track button.

  2. Create a polygon the same way as in the case of Annotation with polygons. Press N or click the Done button on the top panel to complete the polygon.

  3. Pay attention to the fact that the created polygon has a starting point and a direction, these elements are important for annotation of the following frames.

  4. After going a few frames forward press Shift+N, the old polygon will disappear and you can create a new polygon. The new starting point should match the starting point of the previously created polygon (in this example, the top of the left mirror). The direction must also match (in this example, clockwise). After creating the polygon, press N and the intermediate frames will be interpolated automatically.

  5. If you need to change the starting point, right-click on the desired point and select Set starting point. To change the direction, right-click on the desired point and select switch orientation.

There is no need to redraw the polygon every time using Shift+N, instead you can simply move the points or edit a part of the polygon by pressing Shift+Click.

2.2.9.5 - Creating masks

Cutting holes in polygons

Currently, CVAT does not support cutting transparent holes in polygons. However, it is poissble to generate holes in exported instance and class masks. To do this, one needs to define a background class in the task and draw holes with it as additional shapes above the shapes needed to have holes:

The editor window:

The editor

Remember to use z-axis ordering for shapes by [-] and [+, =] keys.

Exported masks:

A class mask An instance mask

Notice that it is currently impossible to have a single instance number for internal shapes (they will be merged into the largest one and then covered by “holes”).

Creating masks

There are several formats in CVAT that can be used to export masks:

  • Segmentation Mask (PASCAL VOC masks)
  • CamVid
  • MOTS
  • ICDAR
  • COCO (RLE-encoded instance masks, guide)
  • TFRecord (over Datumaro, guide):
  • Datumaro

An example of exported masks (in the Segmentation Mask format):

A class mask An instance mask

Important notices:

  • Both boxes and polygons are converted into masks
  • Grouped objects are considered as a single instance and exported as a single mask (label and attributes are taken from the largest object in the group)

Class colors

All the labels have associated colors, which are used in the generated masks. These colors can be changed in the task label properties:

Label colors are also displayed in the annotation window on the right panel, where you can show or hide specific labels (only the presented labels are displayed):

A background class can be:

  • A default class, which is implicitly-added, of black color (RGB 0, 0, 0)
  • background class with any color (has a priority, name is case-insensitive)
  • Any class of black color (RGB 0, 0, 0)

To change background color in generated masks (default is black), change background class color to the desired one.

2.2.10 - Annotation with polylines

Guide to annotating tasks using polylines.

It is used for road markup annotation etc.

Before starting, you need to select the Polyline. You can set a fixed number of points in the Number of points field, then drawing will be stopped automatically.

Click Shape to enter drawing mode. There are two ways to draw a polyline — you either create points by clicking or by dragging a mouse on the screen while holding Shift. When Shift isn’t pressed, you can zoom in/out (when scrolling the mouse wheel) and move (when clicking the mouse wheel and moving the mouse), you can delete previous points by right-clicking on it. Press N again or click the Done button on the top panel to complete the shape. You can delete a point by clicking on it with pressed Ctrl or right-clicking on a point and selecting Delete point. Click with pressed Shift will open a polyline editor. There you can create new points(by clicking or dragging) or delete part of a polygon closing the red line on another point. Press Esc to cancel editing.

2.2.11 - Annotation with points

Guide to annotating tasks using single points or shapes containing multiple points.

2.2.11.1 - Points in shape mode

It is used for face, landmarks annotation etc.

Before you start you need to select the Points. If necessary you can set a fixed number of points in the Number of points field, then drawing will be stopped automatically.

Click Shape to entering the drawing mode. Now you can start annotation of the necessary area. Points are automatically grouped — all points will be considered linked between each start and finish. Press N again or click the Done button on the top panel to finish marking the area. You can delete a point by clicking with pressed Ctrl or right-clicking on a point and selecting Delete point. Clicking with pressed Shift will open the points shape editor. There you can add new points into an existing shape. You can zoom in/out (when scrolling the mouse wheel) and move (when clicking the mouse wheel and moving the mouse) while drawing. You can drag an object after it has been drawn and change the position of individual points after finishing an object.

2.2.11.2 - Linear interpolation with one point

You can use linear interpolation for points to annotate a moving object:

  1. Before you start, select the Points.

  2. Linear interpolation works only with one point, so you need to set Number of points to 1.

  3. After that select the Track.

  4. Click Track to enter the drawing mode left-click to create a point and after that shape will be automatically completed.

  5. Move forward a few frames and move the point to the desired position, this way you will create a keyframe and intermediate frames will be drawn automatically. You can work with this object as with an interpolated track: you can hide it using the Outside, move around keyframes, etc.

  6. This way you’ll get linear interpolation using the Points.

2.2.12 - Annotation with ellipses

Guide to annotating tasks using ellipses.

It is used for road sign annotation etc.

First of all you need to select the ellipse on the controls sidebar.

Choose a Label and click Shape or Track to start drawing. An ellipse can be created the same way as a rectangle, you need to specify two opposite points, and the ellipse will be inscribed in an imaginary rectangle. Press N or click the Done button on the top panel to complete the shape.

You can rotate ellipses using a rotation point in the same way as rectangles.

2.2.13 - Annotation with cuboids

Guide to creating and editing cuboids.

It is used to annotate 3 dimensional objects such as cars, boxes, etc… Currently the feature supports one point perspective and has the constraint where the vertical edges are exactly parallel to the sides.

2.2.13.1 - Creating the cuboid

Before you start, you have to make sure that Cuboid is selected and choose a drawing method ”from rectangle” or “by 4 points”.

Drawing cuboid by 4 points

Choose a drawing method “by 4 points” and click Shape to enter the drawing mode. There are many ways to draw a cuboid. You can draw the cuboid by placing 4 points, after that the drawing will be completed automatically. The first 3 points determine the plane of the cuboid while the last point determines the depth of that plane. For the first 3 points, it is recommended to only draw the 2 closest side faces, as well as the top and bottom face.

A few examples:

Drawing cuboid from rectangle

Choose a drawing method “from rectangle” and click Shape to enter the drawing mode. When you draw using the rectangle method, you must select the frontal plane of the object using the bounding box. The depth and perspective of the resulting cuboid can be edited.

Example:

2.2.13.2 - Editing the cuboid

The cuboid can be edited in multiple ways: by dragging points, by dragging certain faces or by dragging planes. First notice that there is a face that is painted with gray lines only, let us call it the front face.

You can move the cuboid by simply dragging the shape behind the front face. The cuboid can be extended by dragging on the point in the middle of the edges. The cuboid can also be extended up and down by dragging the point at the vertices.

To draw with perspective effects it should be assumed that the front face is the closest to the camera. To begin simply drag the points on the vertices that are not on the gray/front face while holding Shift. The cuboid can then be edited as usual.

If you wish to reset perspective effects, you may right click on the cuboid, and select Reset perspective to return to a regular cuboid.

The location of the gray face can be swapped with the adjacent visible side face. You can do it by right clicking on the cuboid and selecting Switch perspective orientation. Note that this will also reset the perspective effects.

Certain faces of the cuboid can also be edited, these faces are: the left, right and dorsal faces, relative to the gray face. Simply drag the faces to move them independently from the rest of the cuboid.

You can also use cuboids in track mode, similar to rectangles in track mode (basics and advanced) or Track mode with polygons

2.2.14 - Annotation with skeletons

Guide to creating and editing skeletons.

Skeletons should be used as annotations templates when you need to annotate complex objects sharing the same structure (e.g. human pose estimation, facial landmarks, etc.). A skeleton consist of any number of points (also called as elements), joined or not joined by edges. Any point itself is considered like an individual object with its own attributes and properties (like color, occluded, outside, etc). At the same time a skeleton point can exist only within the parent skeleton.

Any skeleton elements can be hidden (by marking them outside) if necessary (for example if a part is out of a frame). Currently there are two formats which support exporting skeletons: CVAT & COCO.

2.2.14.1 - Creating the skeleton

Initial skeleton setup

Unlike other CVAT objects, to start annotating using skeletons, first of all you need to setup a skeleton. You can do that in the label configurator during creating a task/project, or later in created instances.

So, start by clicking Setup skeleton option:

Below the regular label form where you need to add a name, and setup attributes if necessary, you will see a drawing area with some buttons aside:

  • PUT AN IMAGE AS A BACKGROUND - is a helpful feature you can use to draw a skeleton template easier, seeing an example - object you need to annotate in the future.
  • PUT NEW SKELETON POINTS - is activated by default. It is a mode where you can add new skeleton points clicking the drawing area.
  • DRAW AN EDGE BETWEEN TWO POINTS - in this mode you can add an edge, clicking any two points, which are not joined yet.
  • REMOVE A DRAWN SKELETON POINTS - in this mode clicking a point will remove the point and all attached edges. You can also remove an edge only, it will be highligted as red on hover.
  • DOWNLOAD DRAWN TEMPLATE AS AN .SVG - you can download setup configuration to use it in future
  • UPLOAD A TEMPLATE FROM AN .SVG FILE - you can upload previously downloaded configuration

Let’s draw an exampe skeleton - star. After the skeleton is drawn, you can setup each its point. Just hover the point, do right mouse click and click Configure:

Here you can setup a point name, its color and attributes if necessary like for a regular CVAT label:

Press Done button to finish editing the point. Press Continue button to save the skeleton. Continue creating a task/project in a regular way.

For an existing task/project you are not allowed to change a skeleton configuration for now. You can copy/insert skeletons configuration using Raw tab of the label configurator.

Drawing a skeleton from rectangle

In opened job go to left sidebar and find Draw new skeleton control, hover it:

If the control is absent, be sure you have setup at least one skeleton in the corresponding task/project. In a pop-up dropdown you can select between a skeleton Shape and a skeleton Track, depends on your task. Draw a skeleton as a regular bounding box, clicking two points on a canvas:

Well done, you’ve just created the first skeleton.

2.2.14.2 - Editing the skeleton

Editing skeletons on the canvas

A drawn skeleton is wrapped by a bounding box for a user convenience. Using this wrapper the user can edit the skeleton as a regular bounding box, by dragging, resizing, or rotating:

Moreover, each the skeleton point can be dragged itself. After dragging, the wrapping bounding box is adjusted automatically, other points are not affected:

You can use Shortcuts on both a skeleton itself and its elements.

  • Hover the mouse cursor over the bounding box to apply a shortcut on the whole skeleton (like lock, occluded, pinned, keyframe and outside for skeleton tracks)
  • Hover the mouse cursor over one of skeleton points to apply a shortcut to this point (the same shortcuts list, but outside is available also for a skeleton shape elements)

Editing skeletons on the sidebar

Using the sidebar is another way to setup skeleton properties, and attributes. It works a similar way, like for other kinds of objects supported by CVAT, but with some changes:

  • A user is not allowed to switch a skeleton label
  • Outside property is always available for skeleton elements (it does not matter if they are tracks or not)
  • Additional collapse is available for a user, to see a list of skeleton parts

2.2.15 - Annotation with tags

It is used to annotate frames, tags are not displayed in the workspace. Before you start, open the drop-down list in the top panel and select Tag annotation.

The objects sidebar will be replaced with a special panel for working with tags. Here you can select a label for a tag and add it by clicking on the Plus button. You can also customize hotkeys for each label.

If you need to use only one label for one frame, then enable the Automatically go to the next frame checkbox, then after you add the tag the frame will automatically switch to the next.

Tags will be shown in the top left corner of the canvas. You can show/hide them in the settings.

2.2.16 - Models

To deploy the models, you will need to install the necessary components using Semi-automatic and Automatic Annotation guide. To learn how to deploy the model, read Serverless tutorial.

The Models page contains a list of deep learning (DL) models deployed for semi-automatic and automatic annotation. To open the Models page, click the Models button on the navigation bar. The list of models is presented in the form of a table. The parameters indicated for each model are the following:

  • Framework the model is based on
  • model Name
  • model Type:
  • Description - brief description of the model
  • Labels - list of the supported labels (only for the models of the detectors type)

2.2.17 - AI Tools

Overview of semi-automatic and automatic annotation tools available in CVAT.

The tool is designed for semi-automatic and automatic annotation using DL models. The tool is available only if there is a corresponding model. For more details about DL models read the Models section.

Interactors

Interactors are used to create a polygon semi-automatically. Supported DL models are not bound to the label and can be used for any objects. To create a polygon usually you need to use regular or positive points. For some kinds of segmentation negative points are available. Positive points are the points related to the object. Negative points should be placed outside the boundary of the object. In most cases specifying positive points alone is enough to build a polygon. A list of available out-of-the-box interactors is placed below.

  • Before you start, select the magic wand on the controls sidebar and go to the Interactors tab. Then select a label for the polygon and a required DL model. To view help about each of the models, you can click the Question mark icon.

  • Click Interact to enter the interaction mode. Depending on the selected model, the method of markup will also differ. Now you can place positive and/or negative points. The IOG model also uses a rectangle. Left click creates a positive point and right click creates a negative point. After placing the required number of points (the number is different depending on the model), the request will be sent to the server and when the process is complete a polygon will be created. If you are not satisfied with the result, you can set additional points or remove points. To delete a point, hover over the point you want to delete, if the point can be deleted, it will enlarge and the cursor will turn into a cross, then left-click on the point. If you want to postpone the request and create a few more points, hold down Ctrl and continue (the Block button on the top panel will turn blue), the request will be sent after the key is released.

  • In the process of drawing, you can select the number of points in the polygon using the switch.

  • You can use the Selected opacity slider in the Objects sidebar to change the opacity of the polygon. You can read more in the Objects sidebar section.

  • To finish interaction, click on the Done button on the top panel or press N on your keyboard.

  • When the object is finished, you can edit it like a polygon. You can read about editing polygons in the Annotation with polygons section.

Deep extreme cut (DEXTR)

This is an optimized version of the original model, introduced at the end of 2017. It uses the information about extreme points of an object to get its mask. The mask then converted to a polygon. For now this is the fastest interactor on CPU.

Feature backpropagating refinement scheme (f-BRS)

The model allows to get a mask for an object using positive points (should be left-clicked on the foreground), and negative points (should be right-clicked on the background, if necessary). It is recommended to run the model on GPU, if possible.

High Resolution Net (HRNet)

The model allows to get a mask for an object using positive points (should be left-clicked on the foreground), and negative points (should be right-clicked on the background, if necessary). It is recommended to run the model on GPU, if possible.

Inside-Outside-Guidance

The model uses a bounding box and inside/outside points to create a mask. First of all, you need to create a bounding box, wrapping the object. Then you need to use positive and negative points to say the model where is a foreground, and where is a background. Negative points are optional.

Detectors

Detectors are used to automatically annotate one frame. Supported DL models are suitable only for certain labels.

  • Before you start, click the magic wand on the controls sidebar and select the Detectors tab. You need to match the labels of the DL model (left column) with the labels in your task (right column). Then click Annotate.

  • Some of models supports attributes annotation (like facial emotions, for example: serverless/openvino/omz/intel/face-detection-0205). In this case you can also match attributes of the DL model with the attributes of a CVAT label.

  • This action will automatically annotates one frame. In the Automatic annotation section you can read how to make automatic annotation of all frames.

Mask RCNN

The model generates polygons for each instance of an object in the image.

Faster RCNN

The model generates bounding boxes for each instance of an object in the image. In this model, RPN and Fast R-CNN are combined into a single network.

Trackers

Trackers are used to automatically annotate an object using bounding box. Supported DL models are not bound to the label and can be used for any objects.

  • Before you start, select the magic wand on the controls sidebar and go to the Trackers tab. Then select a Label and Tracker for the object and click Track. Then annotate the desired objects with the bounding box in the first frame.

    Start tracking an object

  • All annotated objects will be automatically tracked when you move to the next frame. For tracking, use Next button on the top panel or the F button to move on to the next frame.

    Annotation using a tracker

  • You can enable/disable tracking using tracker switcher on sidebar.

    Tracker switcher

  • Trackable objects have indication on canvas with a model indication.

    Tracker indication

  • You can monitoring the process by the messages appearing at the top. If you change one or more objects, before moving to the next frame, you will see a message that the objects states initialization is taking place. The objects that you do not change are already on the server and therefore do not require initialization. After the objects are initialized, tracking will occur.

    Tracker pop-up window

SiamMask

Fast online Object Tracking and Segmentation. Tracker is able to track different objects in one server request. Trackable object will be tracked automatically if the previous frame was a latest keyframe for the object. Have tracker indication on canvas. SiamMask tracker supported CUDA.

If you plan to track simple non-overlapping objects consider using fast client-side TrackerMIL from OpenCV.

2.2.18 - OpenCV tools

Guide to using Computer Vision algorithms during annotation.

The tool based on Open CV Computer Vision library which is an open-source product that includes many CV algorithms. Some of these algorithms can be used to simplify the annotation process.

First step to work with OpenCV is to load it into CVAT. Click on the toolbar icon, library will be downloaded automatically.

Once it is loaded, the tool’s functionality will be available.

Intelligent scissors

Intelligent scissors is an CV method of creating a polygon by placing points with automatic drawing of a line between them. The distance between the adjacent points is limited by the threshold of action, displayed as a red square which is tied to the cursor.

  • First, select the label and then click on the intelligent scissors button.

  • Create the first point on the boundary of the allocated object. You will see a line repeating the outline of the object.

  • Place the second point, so that the previous point is within the restrictive threshold. After that a line repeating the object boundary will be automatically created between the points.

    To increase or lower the action threshold, hold Ctrl and scroll the mouse wheel. Increasing action threshold will affect the performance. During the drawing process you can remove the last point by clicking on it with the left mouse button.

  • You can also create a boundary manually (like when creating a polygon) by temporarily disabling the automatic line creation. To do that, switch blocking on by pressing Ctrl.

  • In the process of drawing, you can select the number of points in the polygon using the switch.

  • You can use the Selected opacity slider in the Objects sidebar to change the opacity of the polygon. You can read more in the Objects sidebar section.

  • Once all the points are placed, you can complete the creation of the object by clicking on the Done button on the top panel or press N on your keyboard. As a result, a polygon will be created (read more about the polygons in the annotation with polygons).

Histogram Equalization

Histogram equalization is an CV method that improves contrast in an image in order to stretch out the intensity range. This method usually increases the global contrast of images when its usable data is represented by close contrast values. It is useful in images with backgrounds and foregrounds that are both bright or both dark.

  • First, select the image tab and then click on histogram equalization button.

  • Then contrast of current frame will be improved. If you change frame, it will be equalized too. You can disable equalization by clicking histogram equalization button again.

TrackerMIL

Trackers are used to automatically annotate an object on video. The TrackerMIL model is not bound to labels and can be used for any object.

  • Before you start, select the OpenCV tools on the controls sidebar and go to the Trackers tab. Then select a Label and Tracker for the object and click Track. Then annotate the desired objects with the bounding box in the first frame.

    Start tracking an object

  • All annotated objects will be automatically tracked when you move to the next frame. For tracking, use Next button on the top panel or the F button to move on to the next frame.

    Annotation using a tracker

  • You can enable/disable tracking using tracker switcher on sidebar.

    Tracker switcher

  • Trackable objects have indication on canvas with a model indication.

    Tracker indication

  • You can follow the tracking by the messages appearing at the top.

    Tracker pop-up window

2.2.19 - Automatic annotation

Guide to using the automatic annotation of tasks.

Automatic Annotation is used for creating preliminary annotations. To use Automatic Annotation you need a DL model that can be deployed by a CVAT administrator. You can find the list of available models in the Models section.

  1. To launch automatic annotation, you should open the dashboard and find a task which you want to annotate. Then click the Actions button and choose option Automatic Annotation from the dropdown menu.

  2. In the dialog window select a model you need. DL models are created for specific labels, e.g. the Crossroad model was taught using footage from cameras located above the highway and it is best to use this model for the tasks with similar camera angles. If it’s necessary select the Clean old annotations checkbox. Adjust the labels so that the task labels will correspond to the labels of the DL model. For example, let’s consider a task where you have to annotate labels “car” and “person”. You should connect the “person” label from the model to the “person” label in the task. As for the “car” label, you should choose the most fitting label available in the model - the “vehicle” label. If the chosen model supports automatic attributes detection (like facial expressions, for example: serverless/openvino/omz/intel/face-detection-0205), you can also map attributes between the DL model and your task. The task requires to annotate cars only and choosing the “vehicle” label implies annotation of all vehicles, in this case using auto annotation will help you complete the task faster. Click Submit to begin the automatic annotation process.

  3. At runtime - you can see the percentage of completion. You can cancel the automatic annotation by clicking on the Cancelbutton.

  4. The end result of an automatic annotation is an annotation with separate rectangles (or other shapes)

  5. You can combine separate bounding boxes into tracks using the Person reidentification model. To do this, click on the automatic annotation item in the action menu again and select the model of the ReID type (in this case the Person reidentification model). You can set the following parameters:

    • Model Threshold is a maximum cosine distance between objects’ embeddings.
    • Maximum distance defines a maximum radius that an object can diverge between adjacent frames.

  6. You can remove false positives and edit tracks using Split and Merge functions.

2.2.20 - Backup Task and Project

In CVAT you can backup tasks and projects. This can be used to backup a task or project on your PC or to transfer to another server.

Backup

To backup a task or project, open the action menu and select Backup Task or Backup Project.

Backup structure

As a result, you’ll get a zip archive containing data, task or project and task specification and annotations with the following structure:

    .
    ├── data
    │   └── {user uploaded data}
    ├── task.json
    └── annotations.json
  
    .
    ├── task_{id}
    │   ├── data
    │   │   └── {user uploaded data}
    │   ├── task.json
    │   └── annotations.json
    └── project.json
  

Backup API

  • endpoint: /tasks/{id}/backup or /projects/{id}/backup
  • method: GET
  • responses: 202, 201 with zip archive payload

Create from backup

To create a task or project from a backup, go to the tasks or projects page, click the Create from backup button and select the archive you need.

As a result, you’ll get a task containing data, parameters, and annotations of the previously exported task.

Create from backup API

  • endpoint: /api/tasks/backup or /api/projects/backup
  • method: POST
  • Content-Type: multipart/form-data
  • responses: 202, 201 with json payload

2.2.21 - Frame deleting

This section explains how delete and restore frame from a task.

Delete frame

You can delete current frame from a task. This frame will not be presented either in the UI or in the exported annotation. Thus, it is possible to mark corrupted frames that are not subject to annotation.

  1. Go to the Job annotation view and than click on the Delete frame button.

  2. After that you will be asked to confirm frame deleting. Important note: all annotations from that frame will be deleted, unsaved annotations will be saved and the frame will be invisible in the annotation view (Until you make it visible in the settings). If there is some overlap in the task and the deleted frame falls within this interval, then this will cause this frame to become unavailable in another job as well.

  3. When you delete a frame in a job with tracks, you may need adjust some tracks manually. Common adjustments are:

    • Add keyframes at the edges of the deleted interval in order for the interpolation to look correct;
    • Move keyframe start or end keyframe to the correct side of the deleted interval.

Configurate deleted frames visability and navigation

If you need to enable showing the deleted frames, you can do it in the settings.

  1. Go to the settings and chose Player settings.

  2. Click on the Show deleted frames checkbox. And close the settings dialog.

  3. Then you will be able to navigate through deleted frames. But annotation tools will be unavailable. Deleted frames differ in the corresponding overlay.

  4. There are view ways to navigate through deleted frames without enabling this option:

    • Go to the frame via direct navigation methods: navigation slider or frame input field,
    • Go to the frame via direct link.
  5. Navigation with step will not count deleted frames.

Restore deleted frame

You can also restore deleted frames in the task.

  1. Turn on deleted frames visability, as it was told in the previous part, and go to the deleted frame you want to restore.

  2. Click on the Restore icon. The frame will be restored immediately.

2.2.22 - Export/import datasets and upload annotation

This section explains how to download and upload datasets (including annotation, images, and metadata) of projects, tasks, and jobs.

Export dataset

You can export a dataset to a project, task or job.

  1. To download the latest annotations, you have to save all changes first. Сlick the Save button. There is a Ctrl+S shortcut to save annotations quickly.

  2. After that, сlick the Menu button. Exporting and importing of task and project datasets takes place through the Action menu.

  3. Press the Export task dataset button.

  4. Choose the format for exporting the dataset. Exporting and importing is available in:


  5. To download images with the dataset, tick the Save images box.

  6. (Optional) To name the resulting archive, use the Custom name field.

Import dataset

You can import dataset only to a project. In this case, the data will be split into subsets. To import a dataset, do the following on the Project page:

  • Open the Actions menu.
  • Press the Import dataset button.
  • Select the dataset format (if you did not specify a custom name during export, the format will be in the archive name).
  • Drag the file to the file upload area or click on the upload area to select the file through the explorer.

During the import process, you will be able to track the progress of the import.

Upload annotations

In the task or job you can upload an annotation. For this select the item Upload annotation in the menu Action of the task or in the job Menu on the Top panel select the format in which you plan to upload the annotation and select the annotation file or archive via explorer.

It is also possible to import grayscale (1-channel) PNG masks. For grayscale masks provide a list of labels with the number of lines equal to the maximum color index on images. The lines must be in the right order so that line index is equal to the color index. Lines can have arbitrary, but different, colors. If there are gaps in the used color indices in the annotations, they must be filled with arbitrary dummy labels. Example:

q:0,128,0:: # color index 0
aeroplane:10,10,128:: # color index 1
_dummy2:2,2,2:: # filler for color index 2
_dummy3:3,3,3:: # filler for color index 3

KITTI annotations import

You can upload KITTI annotations in two ways: rectangles for the detection task and masks for the segmentation task.

For detection tasks the uploading archive should have the following structure:

└─ annotations.zip/
    ├── labels.txt # optional, labels list for non-original detection labels
    └── <subset_name>/
        ├── label_2/ # left color camera label files
        │   ├── <image_name_1>.txt
        │   ├── <image_name_2>.txt
        │   └── ...

For segmentation tasks the uploading archive should have the following structure:

└─ annotations.zip/
    ├── label_colors.txt # optional, color map for non-original segmentation labels
    └── <subset_name>/
        ├── instance/ # instance segmentation masks

            ├── <image_name_1>.png
            ├── <image_name_2>.png
            └── ...

All annotation files and masks should have structures that are described in the original format specification.

LFW

  • Format specification available here

  • Supported annotations: tags, points.

  • Supported attributes:

    • negative_pairs (should be defined for labels as text): list of image names with mismatched persons.
    • positive_pairs (should be defined for labels as text): list of image names with matched persons.

Import LFW annotation

The uploaded annotations file should be a zip file with the following structure:

<archive_name>.zip/
    └── annotations/
        ├── landmarks.txt # list with landmark points for each image
        ├── pairs.txt # list of matched and mismatched pairs of person
        └── people.txt # optional file with a list of persons name

Full information about the content of annotation files is available here

Export LFW annotation

    ├── landmarks.txt
    ├── pairs.txt
    └── people.txt

Example: create task with images and upload LFW annotations into it

This is one of the possible ways to create a task and add LFW annotations for it.

  • On the task creation page:
    • Add labels that correspond to the names of the persons.
    • For each label define text attributes with names positive_pairs and negative_pairs
    • Add images using zip archive from local repository:
images.zip/
    ├── name1_0001.jpg
    ├── name1_0002.jpg
    ├── ...
    ├── name1_<N>.jpg
    ├── name2_0001.jpg
    ├── ...
  • On the annotation page: Upload annotation -> LFW 1.0 -> choose archive with structure that described in the import section.

2.2.24 - Task synchronization with a repository

Notice: this feature works only if a git repository was specified when the task was created.

  1. At the end of the annotation process, a task is synchronized by clicking Synchronize on the task page. If the synchronization is successful, the button will change to Sychronized in blue:

  2. The annotation is now in the repository in a temporary branch. The next step is to go to the repository and manually create a pull request to the main branch.

  3. After merging the PR, when the annotation is saved in the main branch, the button changes to Merged and is highlighted in green.

If annotation in the task does not correspond annotations in the repository, the sync button will turn red:

2.2.25 - XML annotation format

When you want to download annotations from Computer Vision Annotation Tool (CVAT) you can choose one of several data formats. The document describes XML annotation format. Each format has X.Y version (e.g. 1.0). In general the major version (X) is incremented when the data format has incompatible changes and the minor version (Y) is incremented when the data format is slightly modified (e.g. it has one or several extra fields inside meta information). The document will describe all changes for all versions of XML annotation format.

Version 1.1

There are two different formats for images and video tasks at the moment. The both formats have a common part which is described below. From the previous version flipped tag was added. Also original_size tag was added for interpolation mode to specify frame size. In annotation mode each image tag has width and height attributes for the same purpose.

Annotation

Below you can find description of the data format for images tasks. On each image it is possible to have many different objects. Each object can have multiple attributes. If an annotation task is created with z_order flag then each object will have z_order attribute which is used to draw objects properly when they are intersected (if z_order is bigger the object is closer to camera). In previous versions of the format only box shape was available. In later releases polygon, polyline, points and tags were added. Please see below for more details:

<?xml version="1.0" encoding="utf-8"?>

Interpolation

Below you can find description of the data format for video tasks. The annotation contains tracks. Each track corresponds to an object which can be presented on multiple frames. The same object cannot be presented on the same frame in multiple locations. Each location of the object can have multiple attributes even if an attribute is immutable for the object it will be cloned for each location (a known redundancy).

2.2.27 - Filter

Guide to using the Filter feature in CVAT.

There are some reasons to use the feature:

  1. When you use a filter, objects that don’t match the filter will be hidden.
  2. The fast navigation between frames which have an object of interest. Use the Left Arrow / Right Arrow keys for this purpose or customize the UI buttons by right-clicking and select switching by filter. If there are no objects which correspond to the filter, you will go to the previous / next frame which contains any annotated objects.

To apply filters you need to click on the button on the top panel.

Create a filter

It will open a window for filter input. Here you will find two buttons: Add rule and Add group.

Rules

The Add rule button adds a rule for objects display. A rule may use the following properties:

Supported properties for annotation

Properties Supported values Description
Label all the label names that are in the task label name
Type shape, track or tag type of object
Shape all shape types type of shape
Occluded true or false occluded (read more)
Width number of px or field shape width
Height number of px or field shape height
ServerID number or field ID of the object on the server
(You can find out by forming a link to the object through the Action menu)
ObjectID number or field ID of the object in your client
(indicated on the objects sidebar)
Attributes some other fields including attributes with a
similar type or a specific attribute value
any fields specified by a label

Supported operators for properties

== - Equally; != - Not equal; > - More; >= - More or equal; < - Less; <= - Less or equal;

Any in; Not in - these operators allow you to set multiple values in one rule;

Is empty; is not empty – these operators don’t require to input a value.

Between; Not between – these operators allow you to choose a range between two values.

Like - this operator indicate that the property must contain a value.

Starts with; Ends with - filter by beginning or end.

Some properties support two types of values that you can choose:

You can add multiple rules, to do so click the add rule button and set another rule. Once you’ve set a new rule, you’ll be able to choose which operator they will be connected by: And or Or.

All subsequent rules will be joined by the chosen operator. Click Submit to apply the filter or if you want multiple rules to be connected by different operators, use groups.

Groups

To add a group, click the Add group button. Inside the group you can create rules or groups.

If there is more than one rule in the group, they can be connected by And or Or operators. The rule group will work as well as a separate rule outside the group and will be joined by an operator outside the group. You can create groups within other groups, to do so you need to click the add group button within the group.

You can move rules and groups. To move the rule or group, drag it by the button. To remove the rule or group, click on the Delete button.

If you activate the Not button, objects that don’t match the group will be filtered out. Click Submit to apply the filter. The Cancel button undoes the filter. The Clear filter button removes the filter.

Once applied filter automatically appears in Recent used list. Maximum length of the list is 10.


Sort and filter lists

On the projects, task list on the project page, tasks, jobs, and cloud storage pages, you can use sorting and filters.

The applied filter and sorting will be displayed in the URL of your browser, Thus, you can share the page with sorting and filter applied.

Sort by

You can sort by the following parameters:

  • Jobs list: ID, assignee, updated date, stage, state, task ID, project ID, task name, project name.
  • Tasks list or tasks list on project page: ID, owner, status, assignee, updated date, subset, mode, dimension, project ID, name, project name.
  • Projects list: ID, assignee, owner, status, name, updated date.
  • Cloud storages list: ID, provider type, updated date, display name, resource, credentials, owner, description.

To apply sorting, drag the parameter to the top area above the horizontal bar. The parameters below the horizontal line will not be applied. By moving the parameters you can change the priority, first of all sorting will occur according to the parameters that are above.

Pressing the Sort button switches Ascending sort/Descending sort.

Quick filters

Quick Filters contain several frequently used filters:

  • Assigned to me - show only those projects, tasks or jobs that are assigned to you.
  • Owned by me - show only those projects or tasks that are owned by you.
  • Not completed - show only those projects, tasks or jobs that have a status other than completed.
  • AWS storages - show only AWS cloud storages
  • Azure storages - show only Azure cloud storages
  • Google cloud storages - show only Google cloud storages

Date and time selection

When creating a Last updated rule, you can select the date and time by using the selection window.

You can select the year and month using the arrows or by clicking on the year and month. To select a day, click on it in the calendar, To select the time, you can select the hours and minutes using the scrolling list. Or you can select the current date and time by clicking the Now button. To apply, click Ok.

2.2.28 - Review

Guide to using the Review mode for task validation.

A special mode to check the annotation allows you to point to an object or area in the frame containing an error. Review mode is not available in 3D tasks.

Review

To conduct a review, you need to change the stage to validation for the desired job on the task page and assign a user who will conduct the check. Now the job will open in a fashion review. You can also switch to the Review mode using the UI switcher on the top panel.

Review mode is a UI mode, there is a special Issue tool which you can use to identify objects or areas in the frame and describe the issue.

  • To do this, first click Open an issue icon on the controls sidebar:

  • Then click on a place in the frame to highlight the place or highlight the area by holding the left mouse button and describe the issue. To select an object, right-click on it and select Open an issue or select one of several quick issues. The object or area will be shaded in red.

  • The created issue will appear in the workspace and in the Issues tab on the objects sidebar.

  • Once all the issues are marked, save the annotation, open the menu and select job state rejected or completed.

After the review, other users will be able to see the issues, comment on each issue and change the status of the issue to Resolved.

After the issues are fixed select Finish the job from the menu to finish the task. Or you can switch stage to acceptance on the task page.

Resolve issues

After review, you may see the issues in the Issues tab in the object sidebar.

  • You can use the arrows on the Issues tab to navigate the frames that contain issues.

  • In the workspace you can click on issue, you can send a comment on the issue or, if the issue is resolved, change the status to Resolve. You can remove the issue by clicking Remove (if your account have the appropriate permissions).

  • If few issues were created in one place you can access them by hovering over issue and scrolling the mouse wheel.

If the issue is resolved, you can reopen the issue by clicking the Reopen button.

2.2.29 - Context images for 2d task

Adding additional contextual images to a task.

When you create a task, you can provide the images with additional contextual images. To do this, create a folder related_images and place a folder with a contextual image in it (make sure the folder has the same name as the image to which it should be tied). An example of the structure:

  • root_directory
    • image_1_to_be_annotated.jpg
    • image_2_to_be_annotated.jpg
    • related_images/
      • image_1_to_be_annotated_jpg/
        • context_image_for_image_1.jpg
      • image_2_to_be_annotated_jpg/
        • context_image_for_image_2.jpg
    • subdirectory_example/
      • image_3_to_be_annotated.jpg
      • related_images/
        • image_3_to_be_annotated_jpg/
          • context_image_for_image_3.jpg

The contextual image is displayed in the upper right corner of the workspace. You can hide it by clicking on the corresponding button or maximize the image by clicking on it.

contex_images_1

When the image is maximized, you can rotate it clockwise/counterclockwise and zoom in/out. You can also move the image by moving the mouse while holding down the LMB and zoom in/out by scrolling the mouse wheel. To close the image, just click the X.

contex_images_2

2.2.30 - Shape grouping

Grouping multiple shapes during annotation.

This feature allows us to group several shapes.

You may use the Group Shapes button or shortcuts:

  • G — start selection / end selection in group mode
  • Esc — close group mode
  • Shift+G — reset group for selected shapes

You may select shapes clicking on them or selecting an area.

Grouped shapes will have group_id filed in dumped annotation.

Also you may switch color distribution from an instance (default) to a group. You have to switch Color By Group checkbox for that.

Shapes that don’t have group_id, will be highlighted in white.

2.2.31 - Analytics Monitoring

Using Analytics to monitor usage statistics.

If your CVAT instance was created with analytics support, you can press the Analytics button in the dashboard and analytics and journals will be opened in a new tab.

The analytics allows you to see how much time every user spends on each task and how much work they did over any time range.

It also has an activity graph which can be modified with a number of users shown and a timeframe.

2.2.32 - Command line interface (CLI)

Guide to working with CVAT tasks in the command line interface. This section on GitHub.

Description

A simple command line interface for working with CVAT tasks. At the moment it implements a basic feature set but may serve as the starting point for a more comprehensive CVAT administration tool in the future.

Overview of functionality:

  • Create a new task (supports name, bug tracker, project, labels JSON, local/share/remote files)
  • Delete tasks (supports deleting a list of task IDs)
  • List all tasks (supports basic CSV or JSON output)
  • Download JPEG frames (supports a list of frame IDs)
  • Dump annotations (supports all formats via format string)
  • Upload annotations for a task in the specified format (e.g. ‘YOLO ZIP 1.0’)
  • Export and download a whole task
  • Import a task

Usage

To access the CLI, you need to have python in environment, as well as a clone of the CVAT repository and the necessary modules:

Examples of using

Create a dataset manifest in the current directory with video which contains enough keyframes:

python create.py ~/Documents/video.mp4

Create a dataset manifest with video which does not contain enough keyframes:

python create.py --force --output-dir ~/Documents ~/Documents/video.mp4

Create a dataset manifest with images:

python create.py --output-dir ~/Documents ~/Documents/images/

Create a dataset manifest with pattern (may be used *, ?, []):

python create.py --output-dir ~/Documents "/home/${USER}/Documents/**/image*.jpeg"

2.2.34 - Data preparation on the fly

Description

Data on the fly processing is a way of working with data, the main idea of which is as follows: when creating a task, the minimum necessary meta information is collected. This meta information allows in the future to create necessary chunks when receiving a request from a client.

Generated chunks are stored in a cache of the limited size with a policy of evicting less popular items.

When a request is received from a client, the required chunk is searched for in the cache. If the chunk does not exist yet, it is created using prepared meta information and then put into the cache.

This method of working with data allows:

  • reduce the task creation time.
  • store data in a cache of the limited size with a policy of evicting less popular items.

Unfortunately, this method will not work for all videos with a valid manifest file. If there are not enough keyframes in the video for smooth video decoding, the task will be created in another way. Namely, all chunks will be prepared during task creation, which may take some time.

Uploading a manifest with data

When creating a task, you can upload a manifest.jsonl file along with the video or dataset with images. You can see how to prepare it here.

2.2.35 - Serverless tutorial

Introduction

Computers have now become our partners. They help us to solve routine problems, fix mistakes, find information, etc. It is a natural idea to use their compute power to annotate datasets. There are multiple DL models for classification, object detection, semantic segmentation which can do data annotation for us. And it is relatively simple to integrate your own ML/DL solution into CVAT.

But the world is not perfect and we don’t have a silver bullet which can solve all our problems. Usually, available DL models are trained on public datasets which cannot cover all specific cases. Very often you want to detect objects which cannot be recognized by these models. Our annotation requirements can be so strict that automatically annotated objects cannot be accepted as is, and it is easier to annotate them from scratch. You always need to keep in mind all these mentioned limitations. Even if you have a DL solution which can perfectly annotate 50% of your data, it means that manual work will only be reduced in half.

When we know that DL models can help us to annotate data faster, the next question is how to use them? In CVAT all such DL models are implemented as serverless functions for the Nuclio serverless platform. And there are multiple implemented functions which can be found in the serverless directory such as Mask RCNN, Faster RCNN, SiamMask, Inside Outside Guidance, Deep Extreme Cut, etc. Follow the installation guide to build and deploy these serverless functions. See the user guide to understand how to use these functions in the UI to automatically annotate data.

What is a serverless function and why is it used for automatic annotation in CVAT? Let’s assume that you have a DL model and want to use it for AI-assisted annotation. The naive approach is to implement a Python script which uses the DL model to prepare a file with annotations in a public format like MS COCO or Pascal VOC. After that you can upload the annotation file into CVAT. It works but it is not user-friendly. How to make CVAT run the script for you?

You can pack the script with your DL model into a container which provides a standard interface for interacting with it. One way to do that is to use the function as a service approach. Your script becomes a function inside cloud infrastructure which can be called over HTTP. The Nuclio serverless platform helps us to implement and manage such functions.

CVAT supports Nuclio out of the box if it is built properly. See the installation guide for instructions. Thus if you deploy a serverless function, the CVAT server can see it and call it with appropriate arguments. Of course there are some tricks how to create serverless functions for CVAT and we will discuss them in next sections of the tutorial.

Using builtin DL models in practice

In the tutorial it is assumed that you already have the cloned CVAT GitHub repo. To build CVAT with serverless support you need to run docker-compose command with specific configuration files. In the case it is docker-compose.serverless.yml. It has necessary instructions how to build and deploy Nuclio platform as a docker container and enable corresponding support in CVAT.

docker-compose -f docker-compose.yml -f docker-compose.dev.yml -f components/serverless/docker-compose.serverless.yml up -d --build
docker-compose -f docker-compose.yml -f docker-compose.dev.yml -f components/serverless/docker-compose.serverless.yml ps
   Name                 Command                  State                            Ports
-------------------------------------------------------------------------------------------------------------
cvat         /usr/bin/supervisord             Up             8080/tcp
cvat_db      docker-entrypoint.sh postgres    Up             5432/tcp
cvat_proxy   /docker-entrypoint.sh /bin ...   Up             0.0.0.0:8080->80/tcp,:::8080->80/tcp
cvat_redis   docker-entrypoint.sh redis ...   Up             6379/tcp
cvat_ui      /docker-entrypoint.sh ngin ...   Up             80/tcp
nuclio       /docker-entrypoint.sh sh - ...   Up (healthy)   80/tcp, 0.0.0.0:8070->8070/tcp,:::8070->8070/tcp

Next step is to deploy builtin serverless functions using Nuclio command line tool (aka nuctl). It is assumed that you followed the installation guide and nuctl is already installed on your operating system. Run the following command to check that it works. In the beginning you should not have any deployed serverless functions.

nuctl get functions
No functions found

Let’s see on examples how to use DL models for annotation in different computer vision tasks.

Tracking using SiamMask

In this use case a user needs to annotate all individual objects on a video as tracks. Basically for every object we need to know its location on every frame.

First step is to deploy SiamMask. The deployment process can depend on your operating system. On Linux you can use serverless/deploy_cpu.sh auxiliary script, but below we are using nuctl directly.

Let’s see how it works in the UI. Go to the models tab and check that you can see SiamMask in the list. If you cannot, it means that there are some problems. Go to one of our public channels and ask for help.

Models list with SiamMask

After that, go to the new task page and create a task with this video file. You can choose any task name, any labels, and even another video file if you like. In this case, the Remote sources option was used to specify the video file. Press submit button at the end to finish the process.

Create a video annotation task

Open the task and use AI tools to start tracking an object. Draw a bounding box around an object, and sequentially switch through the frame and correct the restrictive box if necessary.

Start tracking an object

Finally you will get bounding boxes.

SiamMask results

SiamMask model is more optimized to work on Nvidia GPUs. For more information about deploying the model for the GPU, read on.

Object detection using YOLO-v3

First of all let’s deploy the DL model. The deployment process is similar for all serverless functions. Need to run nuctl deploy command with appropriate arguments. To simplify the process, you can use serverless/deploy_cpu.sh command. Inference of the serverless function is optimized for CPU using Intel OpenVINO framework.

Again, go to models tab and check that you can see YOLO v3 in the list. If you cannot by a reason it means that there are some problems. Go to one of our public channels and ask for help.

Let us reuse the task which you created for testing SiamMask serverless function above. Choose the magic wand tool, go to the Detectors tab, and select YOLO v3 model. Press Annotate button and after a couple of seconds you should see detection results. Do not forget to save annotations.

YOLO v3 results

Also it is possible to run a detector for the whole annotation task. Thus CVAT will run the serverless function on every frame of the task and submit results directly into database. For more details please read the guide.

Objects segmentation using Mask-RCNN

If you have a detector, which returns polygons, you can segment objects. One of such detectors is Mask-RCNN. There are several implementations of the detector available out of the box:

  • serverless/openvino/omz/public/mask_rcnn_inception_resnet_v2_atrous_coco is optimized using Intel OpenVINO framework and works well if it is run on an Intel CPU.
  • serverless/tensorflow/matterport/mask_rcnn/ is optimized for GPU.

The deployment process for a serverless function optimized for GPU is similar. Just need to run serverless/deploy_gpu.sh script. It runs mostly the same commands but utilize function-gpu.yaml configuration file instead of function.yaml internally. See next sections if you want to understand the difference.

Note: Please do not run several GPU functions at the same time. In many cases it will not work out of the box. For now you should manually schedule different functions on different GPUs and it requires source code modification. Nuclio autoscaler does not support the local platform (docker).

Now you should be able to annotate objects using segmentation masks.

Mask RCNN results

Adding your own DL models

Choose a DL model

For the tutorial I will choose a popular AI library with a lot of models inside. In your case it can be your own model. If it is based on detectron2 it will be easy to integrate. Just follow the tutorial.

Detectron2 is Facebook AI Research’s next generation library that provides state-of-the-art detection and segmentation algorithms. It is the successor of Detectron and maskrcnn-benchmark. It supports a number of computer vision research projects and production applications in Facebook.

Clone the repository somewhere. I assume that all other experiments will be run from the cloned detectron2 directory.

git clone https://github.com/facebookresearch/detectron2
cd detectron2

Run local experiments

Let’s run a detection model locally. First of all need to install requirements for the library.

In my case I have Ubuntu 20.04 with python 3.8.5. I installed PyTorch 1.8.1 for Linux with pip, python, and CPU inside a virtual environment. Follow opencv-python installation guide to get the library for demo and visualization.

python3 -m venv .detectron2
. .detectron2/bin/activate
pip install torch==1.8.1+cpu torchvision==0.9.1+cpu torchaudio==0.8.1 -f https://download.pytorch.org/whl/torch_stable.html
pip install opencv-python

Install the detectron2 library from your local clone (you should be inside detectron2 directory).

python -m pip install -e .

After the library from Facebook AI Research is installed, we can run a couple of experiments. See the official tutorial for more examples. I decided to experiment with RetinaNet. First step is to download model weights.

curl -O https://dl.fbaipublicfiles.com/detectron2/COCO-Detection/retinanet_R_101_FPN_3x/190397697/model_final_971ab9.pkl

To run experiments let’s download an image with cats from wikipedia.

curl -O https://upload.wikimedia.org/wikipedia/commons/thumb/0/0b/Cat_poster_1.jpg/1920px-Cat_poster_1.jpg

Finally let’s run the DL model inference on CPU. If all is fine, you will see a window with cats and bounding boxes around them with scores.

python demo/demo.py --config-file configs/COCO-Detection/retinanet_R_101_FPN_3x.yaml \
  --input 1920px-Cat_poster_1.jpg --opts MODEL.WEIGHTS model_final_971ab9.pkl MODEL.DEVICE cpu

Cats detected by RetinaNet R101

Next step is to minimize demo/demo.py script and keep code which is necessary to load, run, and interpret output of the model only. Let’s hard code parameters and remove argparse. Keep only code which is responsible for working with an image. There is no common advice how to minimize some code.

Finally you should get something like the code below which has fixed config, read a predefined image, initialize predictor, and run inference. As the final step it prints all detected bounding boxes with scores and labels.

from detectron2.config import get_cfg
from detectron2.data.detection_utils import read_image
from detectron2.engine.defaults import DefaultPredictor
from detectron2.data.datasets.builtin_meta import COCO_CATEGORIES

CONFIG_FILE = "configs/COCO-Detection/retinanet_R_101_FPN_3x.yaml"
CONFIG_OPTS = ["MODEL.WEIGHTS", "model_final_971ab9.pkl", "MODEL.DEVICE", "cpu"]
CONFIDENCE_THRESHOLD = 0.5

def setup_cfg():
    cfg = get_cfg()
    cfg.merge_from_file(CONFIG_FILE)
    cfg.merge_from_list(CONFIG_OPTS)
    cfg.MODEL.RETINANET.SCORE_THRESH_TEST = CONFIDENCE_THRESHOLD
    cfg.MODEL.ROI_HEADS.SCORE_THRESH_TEST = CONFIDENCE_THRESHOLD
    cfg.MODEL.PANOPTIC_FPN.COMBINE.INSTANCES_CONFIDENCE_THRESH = CONFIDENCE_THRESHOLD
    cfg.freeze()
    return cfg


if __name__ == "__main__":
    cfg = setup_cfg()
    input = "1920px-Cat_poster_1.jpg"
    img = read_image(input, format="BGR")
    predictor = DefaultPredictor(cfg)
    predictions = predictor(img)
    instances = predictions['instances']
    pred_boxes = instances.pred_boxes
    scores = instances.scores
    pred_classes = instances.pred_classes
    for box, score, label in zip(pred_boxes, scores, pred_classes):
        label = COCO_CATEGORIES[int(label)]["name"]
        print(box.tolist(), float(score), label)

DL model as a serverless function

When we know how to run the DL model locally, we can prepare a serverless function which can be used by CVAT to annotate data. Let’s see how function.yaml will look like…

Let’s look at faster_rcnn_inception_v2_coco serverless function configuration as an example and try adapting it to our case. First of all let’s invent an unique name for the new function: pth.facebookresearch.detectron2.retinanet_r101. Section annotations describes our function for CVAT serverless subsystem:

  • annotations.name is a display name
  • annotations.type is a type of the serverless function. It can have several different values. Basically it affects input and output of the function. In our case it has detector type and it means that the integrated DL model can generate shapes with labels for an image.
  • annotations.framework is used for information only and can have arbitrary value. Usually it has values like OpenVINO, PyTorch, TensorFlow, etc.
  • annotations.spec describes the list of labels which the model supports. In the case the DL model was trained on MS COCO dataset and the list of labels correspond to the dataset.
  • spec.description is used to provide basic information for the model.

All other parameters are described in Nuclio documentation.

  • spec.handler is the entry point to your function.
  • spec.runtime is the name of the language runtime.
  • spec.eventTimeout is the global event timeout

Next step is to describe how to build our serverless function:

  • spec.build.image is the name of your docker image
  • spec.build.baseImage is the name of a base container image from which to build the function
  • spec.build.directives are commands to build your docker image

In our case we start from Ubuntu 20.04 base image, install curl to download weights for our model, git to clone detectron2 project from GitHub, and python together with pip. Repeat installation steps which we used to setup the DL model locally with minor modifications.

For Nuclio platform we have to specify a couple of more parameters:

  • spec.triggers.myHttpTrigger describes HTTP trigger to handle incoming HTTP requests.
  • spec.platform describes some important parameters to run your functions like restartPolicy and mountMode. Read Nuclio documentation for more details.

Next step is to adapt our source code which we implemented to run the DL model locally to requirements of Nuclio platform. First step is to load the model into memory using init_context(context) function. Read more about the function in Best Practices and Common Pitfalls.

After that we need to accept incoming HTTP requests, run inference, reply with detection results. For the process our entry point is resposible which we specified in our function specification handler(context, event). Again in accordance to function specification the entry point should be located inside main.py.


def init_context(context):
    context.logger.info("Init context...  0%")

    cfg = get_config('COCO-Detection/retinanet_R_101_FPN_3x.yaml')

    cfg.freeze()
    predictor = DefaultPredictor(cfg)

    threshold = float(data.get("threshold", 0.5))
    image = convert_PIL_to_numpy(Image.open(buf), format="BGR")

    predictions = context.user_data.model_handler(image)

    instances = predictions['instances']
    pred_boxes = instances.pred_boxes
    scores = instances.scores
    pred_classes = instances.pred_classes
    results = []

Advanced capabilities

Optimize using GPU

To optimize a function for a specific device (e.g. GPU), basically you just need to modify instructions above to run the function on the target device. In most cases it will be necessary to modify installation instructions only.

For RetinaNet R101 which was added above modifications will look like:

Note: GPU has very limited amount of memory and it doesn’t allow to run multiple serverless functions in parallel for now using free open-source Nuclio version on the local platform because scaling to zero feature is absent. Theoretically it is possible to run different functions on different GPUs, but it requires to change source code on corresponding serverless functions to choose a free GPU.

Debugging a serverless function

Let’s say you have a problem with your serverless function and want to debug it. Of course you can use context.logger.info or similar methods to print the intermediate state of your function. Another way is to debug using Visual Studio Code. Please see instructions below to setup your environment step by step.

Let’s modify our function.yaml to include debugpy package and specify that maxWorkers count is 1. Otherwise both workers will try to use the same port and it will lead to an exception in python code.

        - kind: RUN
          value: pip3 install debugpy

  triggers:
    myHttpTrigger:
      maxWorkers: 1

Change main.py to listen to a port (e.g. 5678). Insert code below in the beginning of your file with entry point.

import debugpy
debugpy.listen(5678)

After these changes deploy the serverless function once again. For serverless/pytorch/facebookresearch/detectron2/retinanet/nuclio/ you should run the command below:

serverless/deploy_cpu.sh serverless/pytorch/facebookresearch/detectron2/retinanet

To debug python code inside a container you have to publish the port (in this tutorial it is 5678). Nuclio deploy command doesn’t support that and we have to workaround it using SSH port forwarding.

  • Install SSH server on your host machine using sudo apt install openssh-server
  • In /etc/ssh/sshd_config host file set GatewayPorts yes
  • Restart ssh service to apply changes using sudo systemctl restart ssh.service

Next step is to install ssh client inside the container and run port forwarding. In the snippet below instead of user and ipaddress provide username and IP address of your host (usually IP address starts from 192.168.). You will need to confirm that you want to connect to your host computer and enter your password. Keep the terminal open after that.

docker exec -it nuclio-nuclio-pth.facebookresearch.detectron2.retinanet_r101 /bin/bash
apt update && apt install -y ssh
ssh -R 5678:localhost:5678 user@ipaddress

See how the latest command looks like in my case:

root@2d6cceec8f70:/opt/nuclio# ssh -R 5678:localhost:5678 nmanovic@192.168.50.188

Finally, add the configuration below into your launch.json. Open Visual Studio Code and run Serverless Debug configuration, set a breakpoint in main.py and try to call the serverless function from CVAT UI. The breakpoint should be triggered in Visual Studio Code and it should be possible to inspect variables and debug code.

      "remoteRoot": "/opt/nuclio"
    }
  ]
}

VS Code debug RetinaNet

Note: In case of changes in the source code, need to re-deploy the function and initiate port forwarding again.

Troubleshooting

First of all need to check that you are using the recommended version of Nuclio framework. In my case it is 1.5.16 but you need to check the installation manual.

nuctl version
Client version:
"Label: 1.5.16, Git commit: ae43a6a560c2bec42d7ccfdf6e8e11a1e3cc3774, OS: linux, Arch: amd64, Go version: go1.14.3"

Check that Nuclio dashboard is running and its version corresponds to nuctl.

docker ps --filter NAME=^nuclio$
CONTAINER ID   IMAGE                                   COMMAND                  CREATED       STATUS                    PORTS                                               NAMES
7ab0c076c927   quay.io/nuclio/dashboard:1.5.16-amd64   "/docker-entrypoint.…"   6 weeks ago   Up 46 minutes (healthy)   80/tcp, 0.0.0.0:8070->8070/tcp, :::8070->8070/tcp   nuclio

Be sure that the model, which doesn’t work, is healthy. In my case Inside Outside Guidance is not running.

docker ps --filter NAME=iog
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

Let’s run it. Go to the root of CVAT repository and run the deploying command.

In this case the container was built some time ago and the port 49154 was assigned by Nuclio. Now the port is used by openvino-dextr as we can see in logs. To prove our hypothesis just need to run a couple of docker commands:

docker container ls -a | grep iog
eb0c1ee46630   cvat/pth.shiyinzhang.iog:latest                              "conda run -n iog pr…"   9 minutes ago       Created                                                                          nuclio-nuclio-pth.shiyinzhang.iog
docker inspect eb0c1ee46630 | grep 49154
            "Error": "driver failed programming external connectivity on endpoint nuclio-nuclio-pth.shiyinzhang.iog (02384290f91b2216162b1603322dadee426afe7f439d3d090f598af5d4863b2d): Bind for 0.0.0.0:49154 failed: port is already allocated",
                        "HostPort": "49154"

To solve the problem let’s just remove the previous container for the function. In this case it is eb0c1ee46630. After that the deploying command works as expected.

docker container rm eb0c1ee46630
eb0c1ee46630

When you investigate an issue with a serverless function, it is extremely useful to look at logs. Just run a couple of commands like docker logs <container>.

docker logs cvat

If before model deployment you see that the NODE PORT is 0, you need to assign it manually. Add the port: 32001 attribute to the function.yaml file of each model, before you deploy the model. Different ports should be prescribed for different models.

Installation serverless functions on Windows 10 with using the Ubuntu subsystem

If you encounter a problem running serverless functions on Windows 10, you can use the Ubuntu subsystem, for this do the following:

  1. Install WSL 2 and Docker Desktop as described in installation manual

  2. Install Ubuntu 18.04 from Microsoft store.

  3. Enable integration for Ubuntu-18.04 in the settings of Docker Desktop in the Resources WSL integration tab:

    Docker WSL integration Ubuntu 18.04

  4. Then you can download and install nuctl on Ubuntu, using the automatic annotation guide.

  5. Install git and clone repository on Ubuntu, as described in the installation manual.

  6. After that, run the commands from this tutorial through Ubuntu.

3 - Administration

This section contains documents for system administrators.

3.1 - Basics

This section contains basic documents for system administrators.

3.1.1 - Installation Guide

A CVAT installation guide for different operating systems.

Quick installation guide

Before you can use CVAT, you’ll need to get it installed. The document below contains instructions for the most popular operating systems. If your system is not covered by the document it should be relatively straight forward to adapt the instructions below for other systems.

Probably you need to modify the instructions below in case you are behind a proxy server. Proxy is an advanced topic and it is not covered by the guide.

For access from China, read sources for users from China section.

Ubuntu 18.04 (x86_64/amd64)

  • Open a terminal window. If you don’t know how to open a terminal window on Ubuntu please read the answer.

  • Type commands below into the terminal window to install docker. More instructions can be found here.

    sudo apt-get update
    sudo apt-get --no-install-recommends install -y \
      apt-transport-https \
      ca-certificates \
      curl \
      gnupg-agent \
      software-properties-common
    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
    sudo add-apt-repository \
      "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
      $(lsb_release -cs) \
      stable"
    sudo apt-get update
    sudo apt-get --no-install-recommends install -y docker-ce docker-ce-cli containerd.io
    
  • Perform post-installation steps to run docker without root permissions.

    sudo groupadd docker
    sudo usermod -aG docker $USER
    

    Log out and log back in (or reboot) so that your group membership is re-evaluated. You can type groups command in a terminal window after that and check if docker group is in its output.

  • Install docker-compose (1.19.0 or newer). Compose is a tool for defining and running multi-container docker applications.

    sudo apt-get --no-install-recommends install -y python3-pip python3-setuptools
    sudo python3 -m pip install setuptools docker-compose
    
  • Clone CVAT source code from the GitHub repository with Git.

    Following command will clone latest develop branch:

    git clone https://github.com/opencv/cvat
    cd cvat
    

    See alternatives if you want to download one of the release versions or use the wget or curl tools.

  • To access CVAT over a network or through a different system, export CVAT_HOST environment variable

    export CVAT_HOST=your-ip-address
    
  • Run docker containers. It will take some time to download the latest CVAT release and other required images like postgres, redis, etc. from DockerHub and create containers.

    docker-compose up -d
    
  • (Optional) Use CVAT_VERSION environment variable to specify the version of CVAT you want to install specific version (e.g v2.1.0, dev). Default behavior: dev images will be pulled for develop branch, and corresponding release images for release versions.

    CVAT_VERSION=dev docker-compose up -d
    
  • Alternative: if you want to build the images locally with unreleased changes see How to pull/build/update CVAT images section

  • You can register a user but by default it will not have rights even to view list of tasks. Thus you should create a superuser. A superuser can use an admin panel to assign correct groups to the user. Please use the command below:

    docker exec -it cvat_server bash -ic 'python3 ~/manage.py createsuperuser'
    

    Choose a username and a password for your admin account. For more information please read Django documentation.

  • Google Chrome is the only browser which is supported by CVAT. You need to install it as well. Type commands below in a terminal window:

    curl https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
    sudo sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
    sudo apt-get update
    sudo apt-get --no-install-recommends install -y google-chrome-stable
    
  • Open the installed Google Chrome browser and go to localhost:8080. Type your login/password for the superuser on the login page and press the Login button. Now you should be able to create a new annotation task. Please read the CVAT manual for more details.

Windows 10

  • Install WSL2 (Windows subsystem for Linux) refer to this official guide. WSL2 requires Windows 10, version 2004 or higher. Note: You may not have to install a Linux distribution unless needed.

  • Download and install Docker Desktop for Windows. Double-click Docker for Windows Installer to run the installer. More instructions can be found here. Official guide for docker WSL2 backend can be found here. Note: Check that you are specifically using WSL2 backend for Docker.

  • Download and install Google Chrome. It is the only browser which is supported by CVAT.

  • Go to windows menu, find Git Bash application and run it. You should see a terminal window.

  • Clone CVAT source code from the GitHub repository.

    The following command will clone the latest develop branch:

    git clone https://github.com/opencv/cvat
    cd cvat
    

    See alternatives if you want to download one of the release versions.

  • Run docker containers. It will take some time to download the latest CVAT release and other required images like postgres, redis, etc. from DockerHub and create containers.

    docker-compose up -d
    
  • (Optional) Use CVAT_VERSION environment variable to specify the version of CVAT you want to install specific version (e.g v2.1.0, dev). Default behavior: dev images will be pulled for develop branch, and corresponding release images for release versions.

    CVAT_VERSION=dev docker-compose up -d
    
  • Alternative: if you want to build the images locally with unreleased changes see How to pull/build/update CVAT images section

  • You can register a user but by default it will not have rights even to view list of tasks. Thus you should create a superuser. A superuser can use an admin panel to assign correct groups to other users. Please use the command below:

    winpty docker exec -it cvat_server bash -ic 'python3 ~/manage.py createsuperuser'
    

    If you don’t have winpty installed or the above command does not work, you may also try the following:

    # enter docker image first
    docker exec -it cvat_server /bin/bash
    # then run

Advanced Topics

How to get CVAT source code

Git (Linux, Mac, Windows)

  1. Install Git on your system if it’s not already installed

    • Ubuntu:
    sudo apt-get --no-install-recommends install -y git
    
  2. Clone CVAT source code from the GitHub repository.

    The command below will clone the default branch (develop):

    git clone https://github.com/opencv/cvat
    cd cvat
    

    To clone specific tag, e.g. v2.1.0:

    git clone -b v2.1.0 https://github.com/opencv/cvat
    cd cvat
    

Wget (Linux, Mac)

To download latest develop branch:

wget https://github.com/opencv/cvat/archive/refs/heads/develop.zip
unzip develop.zip && mv cvat-develop cvat
cd cvat

To download specific tag:

wget https://github.com/opencv/cvat/archive/refs/tags/v1.7.0.zip
unzip v1.7.0.zip && mv cvat-1.7.0 cvat
cd cvat

Curl (Linux, Mac)

To download latest develop branch:

curl -LO https://github.com/opencv/cvat/archive/refs/heads/develop.zip
unzip develop.zip && mv cvat-develop cvat
cd cvat

To download specific tag:

curl -LO https://github.com/opencv/cvat/archive/refs/tags/v1.7.0.zip
unzip v1.7.0.zip && mv cvat-1.7.0 cvat
cd cvat

Deploying CVAT behind a proxy

If you deploy CVAT behind a proxy and do not plan to use any of serverless functions for automatic annotation, the exported environment variables http_proxy, https_proxy and no_proxy should be enough to build images. Otherwise please create or edit the file ~/.docker/config.json in the home directory of the user which starts containers and add JSON such as the following:

{
  "proxies": {
    "default": {
      "httpProxy": "http://proxy_server:port",
      "httpsProxy": "http://proxy_server:port",
      "noProxy": "*.test.example.com,.example2.com"
    }
  }
}

These environment variables are set automatically within any container. Please see the Docker documentation for more details.

Using the Traefik dashboard

If you are customizing the docker compose files and you come upon some unexpected issues, using the Traefik dashboard might be very useful to see if the problem is with Traefik configuration, or with some of the services.

You can enable the Traefik dashboard by uncommenting the following lines from docker-compose.yml

services:
  traefik:
    # Uncomment to get Traefik dashboard
    #   - "--entryPoints.dashboard.address=:8090"
    #   - "--api.dashboard=true"
    # labels:
    #   - traefik.enable=true
    #   - traefik.http.routers.dashboard.entrypoints=dashboard
    #   - traefik.http.routers.dashboard.service=api@internal
    #   - traefik.http.routers.dashboard.rule=Host(`${CVAT_HOST:-localhost}`)

and if you are using docker-compose.https.yml, also uncomment these lines

services:
  traefik:
    command:
      # Uncomment to get Traefik dashboard
      # - "--entryPoints.dashboard.address=:8090"
      # - "--api.dashboard=true"

Note that this “insecure” dashboard is not recommended in production (and if your instance is publicly available); if you want to keep the dashboard in production you should read Traefik’s documentation on how to properly secure it.

Additional components

# Build and run containers with Analytics component support:
docker-compose -f docker-compose.yml \
  -f components/analytics/docker-compose.analytics.yml up -d --build

Semi-automatic and automatic annotation

Please follow this guide.

Stop all containers

The command below stops and removes containers and networks created by up.

docker-compose down

Use your own domain

If you want to access your instance of CVAT outside of your localhost (on another domain), you should specify the CVAT_HOST environment variable, like this:

export CVAT_HOST=<YOUR_DOMAIN>

Share path

You can use a share storage for data uploading during you are creating a task. To do that you can mount it to CVAT docker container. Example of docker-compose.override.yml for this purpose:

version: '3.3'

services:
  cvat_server:
    volumes:
      - cvat_share:/home/django/share:ro
  cvat_worker_default:
    volumes:
      - cvat_share:/home/django/share:ro

volumes:
  cvat_share:
    driver_opts:
      type: none
      device: /mnt/share
      o: bind

You can change the share device path to your actual share.

You can mount your cloud storage as a FUSE and use it later as a share.

Email verification

You can enable email verification for newly registered users. Specify these options in the settings file to configure Django allauth to enable email verification (ACCOUNT_EMAIL_VERIFICATION = ‘mandatory’). Access is denied until the user’s email address is verified.

ACCOUNT_AUTHENTICATION_METHOD = 'username'
ACCOUNT_CONFIRM_EMAIL_ON_GET = True
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_EMAIL_VERIFICATION = 'mandatory'

# Email backend settings for Django
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

Also you need to configure the Django email backend to send emails. This depends on the email server you are using and is not covered in this tutorial, please see Django SMTP backend configuration for details.

Deploy CVAT on the Scaleway public cloud

Please follow this tutorial to install and set up remote access to CVAT on a Scaleway cloud instance with data in a mounted object storage bucket.

Deploy secure CVAT instance with HTTPS

Using Traefik, you can automatically obtain TLS certificate for your domain from Let’s Encrypt, enabling you to use HTTPS protocol to access your website.

To enable this, first set the the CVAT_HOST (the domain of your website) and ACME_EMAIL (contact email for Let’s Encrypt) environment variables:

export CVAT_HOST=<YOUR_DOMAIN>
export ACME_EMAIL=<YOUR_EMAIL>

Then, use the docker-compose.https.yml file to override the base docker-compose.yml file:

docker-compose -f docker-compose.yml -f docker-compose.https.yml up -d

In firewall, ports 80 and 443 must be open for inbound connections from any

Then, the CVAT instance will be available at your domain on ports 443 (HTTPS) and 80 (HTTP, redirects to 443).

How to pull/build/update CVAT images

  • For a CVAT version lower or equal to 2.1.0, you need to pull images using docker because the compose configuration always points to the latest image tag, e.g.

    docker pull cvat/server:v1.7.0
    docker tag cvat/server:v1.7.0 openvino/cvat_server:latest
    
    docker pull cvat/ui:v1.7.0
    docker tag cvat/ui:v1.7.0 openvino/cvat_ui:latest
    

    For CVAT version more than v2.1.0 it’s possible to pull specific version of prebuilt images from DockerHub using CVAT_VERSION environment variable to specify the version (e.g. dev):

    CVAT_VERSION=dev docker-compose pull
    
  • To build images yourself include docker-compose.dev.yml compose config file to docker-compose command. This can be useful if you want to build a CVAT with some source code changes.

    docker-compose -f docker-compose.yml -f docker-compose.dev.yml build
    
  • To update local images to latest or dev tags run:

    CVAT_VERSION=dev docker-compose pull
    

    or

    CVAT_VERSION=latest docker-compose pull
    

Troubleshooting

Sources for users from China

If you stay in China, for installation you need to override the following sources.

  • For use apt update using:

    Ubuntu mirroring help

    Pre-compiled packages:

    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
    

    Or source packages:

    deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
    deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
    deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
    deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
    
  • Docker mirror station

    Add registry mirrors into daemon.json file:

    {
        "registry-mirrors": [
            "http://f1361db2.m.daocloud.io",
            "https://docker.mirrors.ustc.edu.cn",
            "https://hub-mirror.c.163.com",
            "https://https://mirror.ccs.tencentyun.com",
            "https://mirror.ccs.tencentyun.com",
        ]
    }
    
  • For using pip:

    PyPI mirroring help

    pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
    
  • For using npm:

    npm mirroring help

    npm config set registry https://registry.npm.taobao.org/
    
  • Instead of git using gitee:

    CVAT repository on gitee.com

  • For replace acceleration source docker.com run:

    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
    sudo add-apt-repository \
      "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
      $(lsb_release -cs) \
    
  • For replace acceleration source google.com run:

    curl https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
    

HTTPS is not working because of a certificate

If you’re having trouble with SSL connection, to find the cause, you’ll need to get the logs from traefik by running:

docker logs traefik

The logs will help you find out the problem.

If the error is related to a firewall, then:

  • Open ports 80 and 443 for inbound connections from any.
  • Delete acme.json. The location should be something like: /var/lib/docker/volumes/cvat_cvat_letsencrypt/_data/acme.json.

After acme.json is removed, stop all cvat docker containers:

docker-compose -f docker-compose.yml -f docker-compose.https.yml down

Make sure variables set (with your values):

export CVAT_HOST=<YOUR_DOMAIN>
export ACME_EMAIL=<YOUR_EMAIL>

and restart docker:

docker-compose -f docker-compose.yml -f docker-compose.https.yml up -d

3.1.2 - AWS-Deployment Guide

Instructions for deploying CVAT on Nvidia GPU and other AWS machines.

There are two ways of deploying the CVAT.

  1. On Nvidia GPU Machine: Tensorflow annotation feature is dependent on GPU hardware. One of the easy ways to launch CVAT with the tf-annotation app is to use AWS P3 instances, which provides the NVIDIA GPU. Read more about P3 instances here. Overall setup instruction is explained in main readme file, except Installing Nvidia drivers. So we need to download the drivers and install it. For Amazon P3 instances, download the Nvidia Drivers from Nvidia website. For more check Installing the NVIDIA Driver on Linux Instances link.

  2. On Any other AWS Machine: We can follow the same instruction guide mentioned in the installation instructions. The additional step is to add a security group and rule to allow incoming connections.

For any of above, don’t forget to set the CVAT_HOST environemnt variable to the exposed AWS public IP address or hostname:

export CVAT_HOST=your-instance.amazonaws.com

In case of problems with using hostname, you can also use the public IPV4 instead of hostname. For AWS or any cloud based machines where the instances need to be terminated or stopped, the public IPV4 and hostname changes with every stop and reboot. To address this efficiently, avoid using spot instances that cannot be stopped, since copying the EBS to an AMI and restarting it throws problems. On the other hand, when a regular instance is stopped and restarted, the new hostname/IPV4 can be used to set the CVAT_HOST environment variable.

3.1.3 - REST API guide

Instructions on how to interact with REST API and getting swagger documentation.

To access swagger documentation you need to be authorized.

Automatically generated Swagger documentation for Django REST API is available on <cvat_origin>/api/swagger(default: localhost:8080/api/swagger).

Swagger documentation is visible on allowed hosts, Update environment variable in docker-compose.yml file with cvat hosted machine IP or domain name. Example - ALLOWED_HOSTS: 'localhost, 127.0.0.1'.

Make a request to a resource stored on a server and the server will respond with the requested information. The HTTP protocol is used to transport a data. Requests are divided into groups:

  • auth - user authorization queries
  • comments - requests to post/delete comments to issues
  • issues - update, delete and view problem comments
  • jobs -requests to manage the job
  • lambda - requests to work with lambda function
  • projects - project management queries
  • restrictions - requests for restrictions
  • reviews -adding and removing the review of the job
  • server - server information requests
  • tasks - requests to manage tasks
  • users - user management queries

Besides it contains Models. Models - the data type is described using a  schema object.

Each group contains queries related to a different types of HTTP methods such as: GET, POST, PATCH, DELETE, etc. Different methods are highlighted in different color. Each item has a name and description. Clicking on an element opens a form with a name, description and settings input field or an example of json values.

To find out more, read swagger specification.

To try to send a request, click Try it now and type Execute. You’ll get a response in the form of Curl, Request URL and Server response.

3.2 - Advanced

This section contains advanced documents for system administrators.

3.2.1 - Installation Analytics

3.2.2 - Semi-automatic and Automatic Annotation

Information about the installation of components needed for semi-automatic and automatic annotation.

⚠ WARNING: Do not use docker-compose up If you did, make sure all containers are stopped by docker-compose down.

  • To bring up cvat with auto annotation tool, from cvat root directory, you need to run:

    docker-compose -f docker-compose.yml -f components/serverless/docker-compose.serverless.yml up -d
    

    If you did any changes to the docker-compose files, make sure to add --build at the end.

    To stop the containers, simply run:

    docker-compose -f docker-compose.yml -f components/serverless/docker-compose.serverless.yml down
    
  • You have to install nuctl command line tool to build and deploy serverless functions. Download version 1.8.14. It is important that the version you download matches the version in docker-compose.serverless.yml. For example, using wget.

    wget https://github.com/nuclio/nuclio/releases/download/<version>/nuctl-<version>-linux-amd64
    

    After downloading the nuclio, give it a proper permission and do a softlink.

    sudo chmod +x nuctl-<version>-linux-amd64
    sudo ln -sf $(pwd)/nuctl-<version>-linux-amd64 /usr/local/bin/nuctl
    
  • Create cvat project inside nuclio dashboard where you will deploy new serverless functions and deploy a couple of DL models. Commands below should be run only after CVAT has been installed using docker-compose because it runs nuclio dashboard which manages all serverless functions.

    nuctl create project cvat
    
    nuctl deploy --project-name cvat \
      --path serverless/openvino/dextr/nuclio \
      --volume `pwd`/serverless/common:/opt/nuclio/common \
      --platform local
    
    nuctl deploy --project-name cvat \
      --path serverless/openvino/omz/public/yolo-v3-tf/nuclio \
      --volume `pwd`/serverless/common:/opt/nuclio/common \
      --platform local
    

    Note:

    GPU Support

    You will need to install Nvidia Container Toolkit. Also you will need to add --resource-limit nvidia.com/gpu=1 --triggers '{"myHttpTrigger": {"maxWorkers": 1}}' to the nuclio deployment command. You can increase the maxWorker if you have enough GPU memory. As an example, below will run on the GPU:

    nuctl deploy --project-name cvat \
      --path serverless/tensorflow/matterport/mask_rcnn/nuclio \
      --platform local --base-image tensorflow/tensorflow:1.15.5-gpu-py3 \
      --desc "GPU based implementation of Mask RCNN on Python 3, Keras, and TensorFlow." \
      --image cvat/tf.matterport.mask_rcnn_gpu \
      --triggers '{"myHttpTrigger": {"maxWorkers": 1}}' \
      --resource-limit nvidia.com/gpu=1
    

    Note:

    • The number of GPU deployed functions will be limited to your GPU memory.
    • See deploy_gpu.sh script for more examples.
    • For some models (namely SiamMask) you need an Nvidia driver version greater than or equal to 450.80.02.

    Note for Windows users:

    If you want to use nuclio under Windows CVAT installation you should install Nvidia drivers for WSL according to this instruction and follow the steps up to “2.3 Installing Nvidia drivers”. Important requirement: you should have the latest versions of Docker Desktop, Nvidia drivers for WSL, and the latest updates from the Windows Insider Preview Dev channel.

Troubleshooting Nuclio Functions:

  • You can open nuclio dashboard at localhost:8070. Make sure status of your functions are up and running without any error.

  • Test your deployed DL model as a serverless function. The command below should work on Linux and Mac OS.

    image=$(curl https://upload.wikimedia.org/wikipedia/en/7/7d/Lenna_%28test_image%29.png --output - | base64 | tr -d '\n')

  • To check for internal server errors, run docker ps -a to see the list of containers. Find the container that you are interested, e.g., nuclio-nuclio-tf-faster-rcnn-inception-v2-coco-gpu. Then check its logs by docker logs <name of your container> e.g.,

    docker logs nuclio-nuclio-tf-faster-rcnn-inception-v2-coco-gpu
    
  • To debug a code inside a container, you can use vscode to attach to a container instructions. To apply your changes, make sure to restart the container.

    docker restart <name_of_the_container>
    

3.2.3 - LDAP Backed Authentication

Allow users to login with credentials from a central source

The creation of settings.py

When integrating LDAP login, we need to create an overlay to the default CVAT settings located in cvat/settings/production.py. This overlay is where we will configure Django to connect to the LDAP server.

The main issue with using LDAP is that different LDAP implementations have different parameters. So the options used for Active Directory backed authentication will differ if you were to be using FreeIPA.

Update docker-compose.override.yml

In your override config you need to passthrough your settings and tell CVAT to use them by setting the DJANGO_SETTINGS_MODULE variable.

version: '3.3'

services:
  cvat:
    environment:
      DJANGO_SETTINGS_MODULE: settings
    volumes:
      - ./settings.py:/home/django/settings.py:ro

Active Directory Example

The following example should allow for users to authenticate themselves against Active Directory. This example requires a dummy user named cvat_bind. The configuration for the bind account does not need any special permissions.

When updating AUTH_LDAP_BIND_DN, you can write out the account info in two ways. Both are documented in the config below.

This config is known to work with Windows Server 2022, but should work for older versions and Samba’s implementation of Active Directory.

# We are overlaying production
from cvat.settings.production import *

# Custom code below

# Notify CVAT that we are using LDAP authentication
IAM_TYPE = 'LDAP'

# Talking to the LDAP server
AUTH_LDAP_SERVER_URI = "ldap://ad.example.com" # IP Addresses also work
ldap.set_option(ldap.OPT_REFERRALS, 0)

_BASE_DN = "CN=Users,DC=ad,DC=example,DC=com"

# Authenticating with the LDAP server
AUTH_LDAP_BIND_DN = "CN=cvat_bind,%s" % _BASE_DN
# AUTH_LDAP_BIND_DN = "cvat_bind@ad.example.com"
AUTH_LDAP_BIND_PASSWORD = "SuperSecurePassword^21"

AUTH_LDAP_USER_SEARCH = LDAPSearch(
    _BASE_DN,

}

FreeIPA Example

The following example should allow for users to authenticate themselves against FreeIPA. This example requires a dummy user named cvat_bind. The configuration for the bind account does not need any special permissions.

When updating AUTH_LDAP_BIND_DN, you can only write the user info in one way, unlike with Active Directory

This config is known to work with AlmaLinux 8, but may work for other versions and flavors of Enterprise Linux.

3.2.4 - Mounting cloud storage

Instructions on how to mount AWS S3 bucket, Microsoft Azure container or Google Drive as a filesystem.

AWS S3 bucket as filesystem

Ubuntu 20.04

Mount

  1. Install s3fs:

    sudo apt install s3fs
    
  2. Enter your credentials in a file ${HOME}/.passwd-s3fs and set owner-only permissions:

    echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > ${HOME}/.passwd-s3fs
    chmod 600 ${HOME}/.passwd-s3fs
    
  3. Uncomment user_allow_other in the /etc/fuse.conf file: sudo nano /etc/fuse.conf

  4. Run s3fs, replace bucket_name, mount_point:

    s3fs <bucket_name> <mount_point> -o allow_other
    

For more details see here.

Automatically mount

Follow the first 3 mounting steps above.

Using fstab
  1. Create a bash script named aws_s3_fuse(e.g in /usr/bin, as root) with this content (replace user_name on whose behalf the disk will be mounted, backet_name, mount_point, /path/to/.passwd-s3fs):

    #!/bin/bash
    sudo -u <user_name> s3fs <backet_name> <mount_point> -o passwd_file=/path/to/.passwd-s3fs -o allow_other
    exit 0
    
  2. Give it the execution permission:

    sudo chmod +x /usr/bin/aws_s3_fuse
    
  3. Edit /etc/fstab adding a line like this, replace mount_point):

    /absolute/path/to/aws_s3_fuse  <mount_point>     fuse    allow_other,user,_netdev     0       0
    
Using systemd
  1. Create unit file sudo nano /etc/systemd/system/s3fs.service (replace user_name, bucket_name, mount_point, /path/to/.passwd-s3fs):

    [Unit]
    Description=FUSE filesystem over AWS S3 bucket
    After=network.target
    
    [Service]
    Environment="MOUNT_POINT=<mount_point>"
    User=<user_name>
    Group=<user_name>
    ExecStart=s3fs <bucket_name> ${MOUNT_POINT} -o passwd_file=/path/to/.passwd-s3fs -o allow_other
    ExecStop=fusermount -u ${MOUNT_POINT}
    Restart=always
    Type=forking
    
    [Install]
    WantedBy=multi-user.target
    
  2. Update the system configurations, enable unit autorun when the system boots, mount the bucket:

    sudo systemctl daemon-reload
    sudo systemctl enable s3fs.service
    sudo systemctl start s3fs.service
    

Check

A file /etc/mtab contains records of currently mounted filesystems.

cat /etc/mtab | grep 's3fs'

Unmount filesystem

fusermount -u <mount_point>

If you used systemd to mount a bucket:

sudo systemctl stop s3fs.service
sudo systemctl disable s3fs.service

Microsoft Azure container as filesystem

Ubuntu 20.04

Mount

  1. Set up the Microsoft package repository.(More here)

    wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb
    sudo dpkg -i packages-microsoft-prod.deb
    sudo apt-get update
    
  2. Install blobfuse and fuse:

    sudo apt-get install blobfuse fuse
    

    For more details see here

  3. Create environments (replace account_name, account_key, mount_point):

    export AZURE_STORAGE_ACCOUNT=<account_name>
    export AZURE_STORAGE_ACCESS_KEY=<account_key>
    MOUNT_POINT=<mount_point>
    
  4. Create a folder for cache:

    sudo mkdir -p /mnt/blobfusetmp
    
  5. Make sure the file must be owned by the user who mounts the container:

    sudo chown <user> /mnt/blobfusetmp
    
  6. Create the mount point, if it doesn’t exists:

    mkdir -p ${MOUNT_POINT}
    
  7. Uncomment user_allow_other in the /etc/fuse.conf file: sudo nano /etc/fuse.conf

  8. Mount container(replace your_container):

    blobfuse ${MOUNT_POINT} --container-name=<your_container> --tmp-path=/mnt/blobfusetmp -o allow_other
    

Automatically mount

Follow the first 7 mounting steps above.

Using fstab
  1. Create configuration file connection.cfg with same content, change accountName, select one from accountKey or sasToken and replace with your value:

    accountName <account-name-here>
    # Please provide either an account key or a SAS token, and delete the other line.
    accountKey <account-key-here-delete-next-line>
    #change authType to specify only 1
    sasToken <shared-access-token-here-delete-previous-line>
    authType <MSI/SAS/SPN/Key/empty>
    containerName <insert-container-name-here>
    
  2. Create a bash script named azure_fuse(e.g in /usr/bin, as root) with content below (replace user_name on whose behalf the disk will be mounted, mount_point, /path/to/blobfusetmp,/path/to/connection.cfg):

    #!/bin/bash
    sudo -u <user_name> blobfuse <mount_point> --tmp-path=/path/to/blobfusetmp  --config-file=/path/to/connection.cfg -o allow_other
    exit 0
    
  3. Give it the execution permission:

    sudo chmod +x /usr/bin/azure_fuse
    
  4. Edit /etc/fstab with the blobfuse script. Add the following line(replace paths):

    /absolute/path/to/azure_fuse </path/to/desired/mountpoint> fuse allow_other,user,_netdev
    
Using systemd
  1. Create unit file sudo nano /etc/systemd/system/blobfuse.service. (replace user_name, mount_point, container_name,/path/to/connection.cfg):

    [Unit]
    Description=FUSE filesystem over Azure container
    After=network.target
    
    [Service]
    Environment="MOUNT_POINT=<mount_point>"
    User=<user_name>
    Group=<user_name>
    ExecStart=blobfuse ${MOUNT_POINT} --container-name=<container_name> --tmp-path=/mnt/blobfusetmp --config-file=/path/to/connection.cfg -o allow_other
    ExecStop=fusermount -u ${MOUNT_POINT}
    Restart=always
    Type=forking
    
    [Install]
    WantedBy=multi-user.target
    
  2. Update the system configurations, enable unit autorun when the system boots, mount the container:

    sudo systemctl daemon-reload
    sudo systemctl enable blobfuse.service
    sudo systemctl start blobfuse.service
    

    Or for more detail see here

Check

A file /etc/mtab contains records of currently mounted filesystems.

cat /etc/mtab | grep 'blobfuse'

Unmount filesystem

fusermount -u <mount_point>

If you used systemd to mount a container:

sudo systemctl stop blobfuse.service
sudo systemctl disable blobfuse.service

Google Drive as filesystem

Ubuntu 20.04

Mount

To mount a google drive as a filesystem in user space(FUSE) you can use google-drive-ocamlfuse To do this follow the instructions below:

  1. Install google-drive-ocamlfuse:

    sudo add-apt-repository ppa:alessandro-strada/ppa
    sudo apt-get update
    sudo apt-get install google-drive-ocamlfuse
    
  2. Run google-drive-ocamlfuse without parameters:

    google-drive-ocamlfuse
    

    This command will create the default application directory (~/.gdfuse/default), containing the configuration file config (see the wiki page for more details about configuration). And it will start a web browser to obtain authorization to access your Google Drive. This will let you modify default configuration before mounting the filesystem.

    Then you can choose a local directory to mount your Google Drive (e.g.: ~/GoogleDrive).

  3. Create the mount point, if it doesn’t exist(replace mount_point):

    mountpoint="<mount_point>"
    mkdir -p $mountpoint
    
  4. Uncomment user_allow_other in the /etc/fuse.conf file: sudo nano /etc/fuse.conf

  5. Mount the filesystem:

    google-drive-ocamlfuse -o allow_other $mountpoint
    

Automatically mount

Follow the first 4 mounting steps above.

Using fstab
  1. Create a bash script named gdfuse(e.g in /usr/bin, as root) with this content (replace user_name on whose behalf the disk will be mounted, label, mount_point):

    #!/bin/bash
    sudo -u <user_name> google-drive-ocamlfuse -o allow_other -label <label> <mount_point>
    exit 0
    
  2. Give it the execution permission:

    sudo chmod +x /usr/bin/gdfuse
    
  3. Edit /etc/fstab adding a line like this, replace mount_point):

    /absolute/path/to/gdfuse  <mount_point>     fuse    allow_other,user,_netdev     0       0
    

    For more details see here

Using systemd
  1. Create unit file sudo nano /etc/systemd/system/google-drive-ocamlfuse.service. (replace user_name, label(default label=default), mount_point):

    [Unit]
    Description=FUSE filesystem over Google Drive
    After=network.target
    
    [Service]
    Environment="MOUNT_POINT=<mount_point>"
    User=<user_name>
    Group=<user_name>
    ExecStart=google-drive-ocamlfuse -label <label> ${MOUNT_POINT}
    ExecStop=fusermount -u ${MOUNT_POINT}
    Restart=always
    Type=forking
    
    [Install]
    WantedBy=multi-user.target
    
  2. Update the system configurations, enable unit autorun when the system boots, mount the drive:

    sudo systemctl daemon-reload
    sudo systemctl enable google-drive-ocamlfuse.service
    sudo systemctl start google-drive-ocamlfuse.service
    

    For more details see here

Check

A file /etc/mtab contains records of currently mounted filesystems.

cat /etc/mtab | grep 'google-drive-ocamlfuse'

Unmount filesystem

fusermount -u <mount_point>

If you used systemd to mount a drive:

sudo systemctl stop google-drive-ocamlfuse.service
sudo systemctl disable google-drive-ocamlfuse.service

3.2.5 - Backup guide

Instructions on how to backup CVAT data with Docker.

About CVAT data volumes

Docker volumes are used to store all CVAT data:

  • cvat_db: PostgreSQL database files, used to store information about users, tasks, projects, annotations, etc. Mounted into cvat_db container by /var/lib/postgresql/data path.

  • cvat_data: used to store uploaded and prepared media data. Mounted into cvat container by /home/django/data path.

  • cvat_keys: used to store user ssh keys needed for synchronization with a remote Git repository. Mounted into cvat container by /home/django/keys path.

  • cvat_logs: used to store logs of CVAT backend processes managed by supevisord. Mounted into cvat container by /home/django/logs path.

  • cvat_events: this is an optional volume that is used only when Analytics component is enabled and is used to store Elasticsearch database files. Mounted into cvat_elasticsearch container by /usr/share/elasticsearch/data path.

How to backup all CVAT data

All CVAT containers should be stopped before backup:

docker-compose stop

Please don’t forget to include all the compose config files that were used in the docker-compose command using the -f parameter.

Backup data:

mkdir backup
docker run --rm --name temp_backup --volumes-from cvat_db -v $(pwd)/backup:/backup ubuntu tar -czvf /backup/cvat_db.tar.gz /var/lib/postgresql/data
docker run --rm --name temp_backup --volumes-from cvat_server -v $(pwd)/backup:/backup ubuntu tar -czvf /backup/cvat_data.tar.gz /home/django/data
# [optional]
docker run --rm --name temp_backup --volumes-from cvat_elasticsearch -v $(pwd)/backup:/backup ubuntu tar -czvf /backup/cvat_events.tar.gz /usr/share/elasticsearch/data

Make sure the backup archives have been created, the output of ls backup command should look like this:

ls backup
cvat_data.tar.gz  cvat_db.tar.gz  cvat_events.tar.gz

How to restore CVAT from backup

Warning: use exactly the same CVAT version to restore DB. Otherwise it will not work because between CVAT releases the layout of DB can be changed. You always can upgrade CVAT later. It will take care to migrate your data properly internally.

Note: CVAT containers must exist (if no, please follow the installation guide). Stop all CVAT containers:

docker-compose stop

Restore data:

cd <path_to_backup_folder>
docker run --rm --name temp_backup --volumes-from cvat_db -v $(pwd):/backup ubuntu bash -c "cd /var/lib/postgresql/data && tar -xvf /backup/cvat_db.tar.gz --strip 4"
docker run --rm --name temp_backup --volumes-from cvat_server -v $(pwd):/backup ubuntu bash -c "cd /home/django/data && tar -xvf /backup/cvat_data.tar.gz --strip 3"
# [optional]
docker run --rm --name temp_backup --volumes-from cvat_elasticsearch -v $(pwd):/backup ubuntu bash -c "cd /usr/share/elasticsearch/data && tar -xvf /backup/cvat_events.tar.gz --strip 4"

After that run CVAT as usual:

docker-compose up -d

3.2.6 - Upgrade guide

Instructions for upgrading CVAT deployed with docker compose

Upgrade guide

To upgrade CVAT, follow these steps:

  • It is highly recommended backup all CVAT data before updating, follow the backup guide and backup all CVAT volumes.

  • Go to the previously cloned CVAT directory and stop all CVAT containers with:

    docker-compose down
    

    If you have included additional components, include all compose configuration files that are used, e.g.:

    docker-compose -f docker-compose.yml -f components/analytics/docker-compose.analytics.yml down
    
  • Update CVAT source code by any preferable way: clone with git or download zip file from GitHub. Note that you need to download the entire source code, not just the docker-compose configuration file. Check the installation guide for details.

  • Verify settings: The installation process is changed/modified from version to version and you may need to export some environment variables, for example CVAT_HOST.

  • Update local CVAT images. Pull or build new CVAT images, see How to pull/build/update CVAT images section for details.

  • Start CVAT with:

    docker-compose up -d
    

    When CVAT starts, it will upgrade its DB in accordance with the latest schema. It can take time especially if you have a lot of data. Please do not terminate the migration and wait till the process is complete. You can monitor the startup process with the following command:

    docker logs cvat_server -f
    

How to udgrade CVAT from v1.7.0 to v2.1.0.

Step by step commands how to udgrade CVAT from v1.7.0 to v2.1.0. Let’s assume that you have CVAT v1.7.0 working.

    If you have any problems with installing dependencies from cvat/requirements/*.txt, you may need to reinstall your system python In some cases after system update it can be configured incorrectly and cannot compile some native modules

    Make sure Homebrew lib path is in DYLD_LIBRARY_PATH. For Apple Silicon: export DYLD_LIBRARY_PATH=/opt/homebrew/lib:$DYLD_LIBRARY_PATH

    Homebrew will install FFMpeg 5.0 by default, which does not work, so you should install 4.X. You can install older 4.X FFMpeg using Homebrew like that:

     cd "$(brew --repo homebrew/core)"
     git checkout addd616edc9134f057e33694c420f4900be59db8
     brew unlink ffmpeg
     HOMEBREW_NO_AUTO_UPDATE=1 brew install ffmpeg
     git checkout master
    

    if you are still facing error Running setup.py install for av ... error, you may try more radical variant

     cd "$(brew --repo homebrew/core)"
     git checkout addd616edc9134f057e33694c420f4900be59db8
     brew uninstall ffmpeg --force
     HOMEBREW_NO_AUTO_UPDATE=1 brew install ffmpeg
     git checkout master
    

    If you faced with error Failed building wheel for h5py, you may need install hdf5

    brew install hdf5
    export HDF5_DIR="$(brew --prefix hdf5)"
    pip install --no-binary=h5py h5py
    

    If you faced with error OSError: Could not find library geos_c or load any of its variants ['libgeos_c.so.1', 'libgeos_c.so']. You may fix this using

    sudo ln -s /opt/homebrew/lib/libgeos_c.dylib /usr/local/lib
    

    On Mac with Apple Silicon (M1) in order to install TensorFlow you will have to edit cvat/requirements/base.txt. Change tensorflow to tensorflow-macos May need to downgrade version Python to 3.9.* or upgrade version tensorflow-macos

  • Create a super user for CVAT:

    python manage.py createsuperuser
    
  • Install npm packages for UI (run the following command from CVAT root directory):

    yarn --frozen-lockfile
    

    Note for Mac users

    If you faced with error

    Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (57)

  • Install Docker Engine and Docker-Compose

  • Pull OpenPolicyAgent Docker-image (run from CVAT root dir):

    sudo docker-compose -f docker-compose.yml -f docker-compose.dev.yml up cvat_opa
    

Run CVAT

  • Start npm UI debug server (run the following command from CVAT root directory):

    • If you want to run CVAT in localhost:
      yarn run start:cvat-ui
      
    • If you want to access CVAT from outside of your host:
      CVAT_UI_HOST='<YOUR_HOST_IP>' yarn run start:cvat-ui
      
  • Open a new terminal window.

  • Run VScode from the virtual environment (run the following command from CVAT root directory):

    source .env/bin/activate && code
    
  • Inside VScode, Open CVAT root dir

  • Select server: debug configuration and run it (F5) to run REST server and its workers

  • Make sure that Uncaught Exceptions option under breakpoints section is unchecked

  • If you choose to run CVAT in localhost: Select server: chrome configuration and run it (F5) to open CVAT in Chrome

  • Alternative: If you changed CVAT_UI_HOST just enter <YOUR_HOST_IP>:3000 in your browser.

You have done! Now it is possible to insert breakpoints and debug server and client of the tool. Instructions for running tests locally are available here.

Note for Windows users

You develop CVAT under WSL (Windows subsystem for Linux) following next steps.

  • Install WSL using this guide.

  • Following this guide install Ubuntu 18.04 Linux distribution for WSL.

  • Run Ubuntu using start menu link or execute next command

    wsl -d Ubuntu-18.04
    
  • Run all commands from this installation guide in WSL Ubuntu shell.

  • You might have to manually start the redis server in wsl before you can start the configuration inside Visual Studio Code. You can do this with sudo service redis-server start. Alternatively you can also use a redis docker image instead of using the redis-server locally.

Note for Mac users

  • You might have to manually start the redis server. You can do this with redis-server. Alternatively you can also use a redis docker image instead of using the redis-server locally.

4.2 - Setup additional components in development environment

Deploying a DL model as a serverless function and Cypress tests.

DL models as serverless functions

Follow this guide to install Nuclio:

  • You have to install nuctl command line tool to build and deploy serverless functions.
  • The simplest way to explore Nuclio is to run its graphical user interface (GUI) of the Nuclio dashboard. All you need in order to run the dashboard is Docker. See nuclio documentation for more details.
  • Create cvat project inside nuclio dashboard where you will deploy new serverless functions and deploy a couple of DL models.
nuctl create project cvat

4.3 - JavaScript/Typescript coding style

Information about JavaScript/Typescript coding style that is used in CVAT development.

We use the Airbnb JavaScript Style Guide for JavaScript code with a little exception - we prefer 4 spaces for indentation of nested blocks and statements.

4.4 - Branching model

Information about the branching model that is used in the project.

The project uses a successful Git branching model. Thus it has a couple of branches. Some of them are described below:

  • origin/master to be the main branch where the source code of HEAD always reflects a production-ready state

  • origin/develop to be the main branch where the source code of HEAD always reflects a state with the latest delivered development changes for the next release. Some would call this the “integration branch”.

4.5 - Using the issue tracker

Information and rules for using the issue tracker.

The issue tracker is the preferred channel for bug reports, features requests and submitting pull requests, but please respect the following restrictions:

  • Please do not use the issue tracker for personal support requests (use Stack Overflow).

  • Please do not derail or troll issues. Keep the discussion on topic and respect the opinions of others.

4.6 - Bug reports

Guidelines and an example of how to report a bug.

A bug is a demonstrable problem that is caused by the code in the repository. Good bug reports are extremely helpful - thank you!

Guidelines for bug reports:

  1. Use the GitHub issue search — check if the issue has already been reported.

  2. Check if the issue has been fixed — try to reproduce it using the latest develop branch in the repository.

  3. Isolate the problem — ideally create a reduced test case.

A good bug report shouldn’t leave others needing to chase you up for more information. Please try to be as detailed as possible in your report. What is your environment? What steps will reproduce the issue? What browser(s) and OS experience the problem? What would you expect to be the outcome? All these details will help people to fix any potential bugs.

Example:

Short and descriptive example bug report title

A summary of the issue and the browser/OS environment in which it occurs. If suitable, include the steps required to reproduce the bug.

  1. This is the first step
  2. This is the second step
  3. Further steps, etc.

Any other information you want to share that is relevant to the issue being reported. This might include the lines of code that you have identified as causing the bug, and potential solutions (and your opinions on their merits).

4.7 - Feature requests

Information on requesting new features.

Feature requests are welcome. But take a moment to find out whether your idea fits with the scope and aims of the project. It’s up to you to make a strong case to convince the project’s developers of the merits of this feature. Please provide as much detail and context as possible.

4.8 - Pull requests

Instructions on how to create a pull request.

Good pull requests - patches, improvements, new features - are a fantastic help. They should remain focused in scope and avoid containing unrelated commits.

Please ask first before embarking on any significant pull request (e.g. implementing features, refactoring code, porting to a different language), otherwise you risk spending a lot of time working on something that the project’s developers might not want to merge into the project.

Please adhere to the coding conventions used throughout a project (indentation, accurate comments, etc.) and any other requirements (such as test coverage).

Follow this process if you’d like your work considered for inclusion in the project:

  1. Fork the project, clone your fork, and configure the remotes:

    # Clone your fork of the repo into the current directory
    git clone https://github.com/<your-username>/<repo-name>
    # Navigate to the newly cloned directory
    cd <repo-name>
    # Assign the original repo to a remote called "upstream"
    git remote add upstream https://github.com/<upstream-owner>/<repo-name>
    
  2. If you cloned a while ago, get the latest changes from upstream:

    git checkout <dev-branch>
    git pull upstream <dev-branch>
    
  3. Create a new topic branch (off the main project development branch) to contain your feature, change, or fix:

    git checkout -b <topic-branch-name>
    
  4. Commit your changes in logical chunks. Please adhere to these git commit message guidelines or your code is unlikely be merged into the main project. Use Git’s interactive rebase feature to tidy up your commits before making them public.

  5. Locally merge (or rebase) the upstream development branch into your topic branch:

    git pull [--rebase] upstream <dev-branch>
    
  6. Push your topic branch up to your fork:

    git push origin <topic-branch-name>
    
  7. Open a Pull Request with a clear title and description.

IMPORTANT: By submitting a patch, you agree to allow the project owner to license your work under the same license as that used by the project.

4.9 - How to add a new annotation format support

Instructions on adding support for new annotation formats. This section on GitHub.
  1. Add a python script to dataset_manager/formats
  2. Add an import statement to registry.py.
  3. Implement some importers and exporters as the format requires.

Each format is supported by an importer and exporter.

It can be a function or a class decorated with importer or exporter from registry.py. Examples:

@importer(name="MyFormat", version="1.0", ext="ZIP")
def my_importer(file_object, task_data, **options):
  ...

@importer(name="MyFormat", version="2.0", ext="XML")
class my_importer(file_object, task_data, **options):
  def __call__(self, file_object, task_data, **options):
    ...

@exporter(name="MyFormat", version="1.0", ext="ZIP"):
def my_exporter(file_object, task_data, **options):
  ...

Each decorator defines format parameters such as:

  • name

  • version

  • file extension. For the importer it can be a comma-separated list. These parameters are combined to produce a visible name. It can be set explicitly by the display_name argument.

Importer arguments:

  • file_object - a file with annotations or dataset
  • task_data - an instance of TaskData class.

Exporter arguments:

  • file_object - a file for annotations or dataset

  • task_data - an instance of TaskData class.

  • options - format-specific options. save_images is the option to distinguish if dataset or just annotations are requested.

TaskData provides many task properties and interfaces to add and read task annotations.

Public members:

  • TaskData. Attribute - class, namedtuple('Attribute', 'name, value')

  • TaskData. LabeledShape - class, namedtuple('LabeledShape', 'type, frame, label, points, occluded, attributes, group, z_order')

  • TrackedShape - namedtuple('TrackedShape', 'type, points, occluded, frame, attributes, outside, keyframe, z_order')

  • Track - class, namedtuple('Track', 'label, group, shapes')

  • Tag - class, namedtuple('Tag', 'frame, label, attributes, group')

  • Frame - class, namedtuple('Frame', 'frame, name, width, height, labeled_shapes, tags')

  • TaskData. shapes - property, an iterator over LabeledShape objects

  • TaskData. tracks - property, an iterator over Track objects

  • TaskData. tags - property, an iterator over Tag objects

  • TaskData. meta - property, a dictionary with task information

  • TaskData. group_by_frame() - method, returns an iterator over Frame objects, which groups annotation objects by frame. Note that TrackedShape s will be represented as LabeledShape s.

  • TaskData. add_tag(tag) - method, tag should be an instance of the Tag class

4.10 - Running tests

Instructions on how to run all existence tests.

E2E tests

Initial steps:

  1. Run CVAT instance:
    docker-compose \
              -f docker-compose.yml \
              -f docker-compose.dev.yml \
              -f components/serverless/docker-compose.serverless.yml \
              -f tests/docker-compose.file_share.yml up -d
    
  2. Add test user in CVAT:
    docker exec -i cvat_server \
              /bin/bash -c \
              "echo \"from django.contrib.auth.models import User; User.objects.create_superuser('admin', 'admin@localhost.company', '12qwaszx')\" | python3 ~/manage.py shell"
    
  3. Install npm dependencies:
    cd tests
    yarn --frozen-lockfile
    

Running tests

yarn run cypress:run:chrome
yarn run cypress:run:chrome:canvas3d

REST API, SDK and CLI tests

Initial steps

  1. Install all necessary requirements before running REST API tests:
    pip install -r ./tests/python/requirements.txt
    

Running tests

Run all REST API tests:

pytest ./tests/python

This command will automatically start all necessary docker containers.

If you want to start/stop these containers without running tests use special options for it:

pytest ./tests/python --start-services
pytest ./tests/python --stop-services

If you need to rebuild your CVAT images add --rebuild option:

pytest ./tests/python --rebuild

Unit tests

Initial steps

  1. Install necessary Python dependencies:
    pip install -r cvat/requirements/testing.txt
    
  2. Install npm dependencies:
    yarn --frozen-lockfile
    
  3. Run CVAT instance
    docker-compose -f docker-compose.yml -f docker-compose.dev.yml up -d
    

Running tests

  1. Python tests
    python manage.py test --settings cvat.settings.testing cvat/apps utils/cli
    
  2. JS tests
    cd cvat-core
    yarn run test
    

4.11 - REST API design principles

Information on using the REST API scheme and principles of its design.

REST API scheme

Common scheme for our REST API is <VERB> [namespace] <objects> <id> <action>.

  • VERB can be POST, GET, PATCH, PUT, DELETE.
  • namespace should scope some specific functionality like auth, lambda. It is optional in the scheme.
  • Typical objects are tasks, projects, jobs.
  • When you want to extract a specific object from a collection, just specify its id.
  • An action can be used to simplify REST API or provide an endpoint for entities without objects endpoint like annotations, data, data/meta. Note: action should not duplicate other endpoints without a reason.

Design principles

  • Use nouns instead of verbs in endpoint paths. For example, POST /api/tasks instead of POST /api/tasks/create.
  • Accept and respond with JSON whenever it is possible
  • Name collections with plural nouns (e.g. /tasks, /projects)
  • Try to keep the API structure flat. Prefer two separate endpoints for /projects and /tasks instead of /projects/:id1/tasks/:id2. Use filters to extract necessary information like /tasks/:id2?project=:id1. In some cases it is useful to get all tasks. If the structure is hierarchical, it cannot be done easily. Also you have to know both :id1 and :id2 to get information about the task. Note: for now we accept GET /tasks/:id2/jobs but it should be replaced by /jobs?task=:id2 in the future.
  • Handle errors gracefully and return standard error codes (e.g. 201, 400)
  • Allow filtering, sorting, and pagination
  • Maintain good security practices
  • Cache data to improve performance
  • Versioning our APIs. It should be done when you delete an endpoint or modify its behaviors. Versioning uses a schema with Accept header with vendor media type.

target_metric bool, date, datetime, dict, float, int, list, str, none_type The primary metric used for quality estimation * accuracy - ACCURACY * precision - PRECISION * recall - RECALL [optional]
target_metric_threshold float Defines the minimal quality requirements in terms of the selected target metric. [optional]
max_validations_per_job int The maximum number of job validation attempts for the job assignee. The job can be automatically accepted if the job quality is above the required threshold, defined by the target threshold parameter. [optional]
iou_threshold float Used for distinction between matched / unmatched shapes [optional]
oks_sigma float Like IoU threshold, but for points. The percent of the bbox side, used as the radius of the circle around the GT point, where the checked point is expected to be. For boxes with different width and height, the "side" is computed as a geometric mean of the width and height. Read more: https://cocodataset.org/#keypoints-eval [optional]
point_size_base bool, date, datetime, dict, float, int, list, str, none_type When comparing point annotations (including both separate points and point groups), the OKS sigma parameter defines matching area for each GT point based to the object size. The point size base parameter allows to configure how to determine the object size. If image_size, the image size is used. Useful if each point annotation represents a separate object or boxes grouped with points do not represent object boundaries. If group_bbox_size, the object size is based on the point group bbox size. Useful if each point group represents an object or there is a bbox grouped with points, representing the object size. * image_size - IMAGE_SIZE * group_bbox_size - GROUP_BBOX_SIZE [optional]
line_thickness float Thickness of polylines, relatively to the (image area) ^ 0.5. The distance to the boundary around the GT line, inside of which the checked line points should be [optional]

compare_line_orientation bool Enables or disables polyline orientation comparison [optional]
line_orientation_threshold float The minimal gain in the GT IoU between the given and reversed line directions to consider the line inverted. Only used when the ‘compare_line_orientation’ parameter is true [optional]
compare_groups bool Enables or disables annotation group checks [optional]
group_match_threshold float Minimal IoU for groups to be considered matching. Only used when the ‘compare_groups’ parameter is true [optional]
check_covered_annotations bool Check for partially-covered annotations, useful in segmentation tasks [optional]
object_visibility_threshold float Minimal visible area percent of the spatial annotations (polygons, masks) for reporting covered annotations. Only used when the ‘object_visibility_threshold’ parameter is true [optional]
panoptic_comparison bool Use only the visible part of the masks and polygons in comparisons [optional]
compare_attributes bool Enables or disables annotation attribute comparison [optional]
match_empty_frames bool Count empty frames as matching. This affects target metrics like accuracy in cases there are no annotations. If disabled, frames without annotations are counted as not matching (accuracy is 0). If enabled, accuracy will be 1 instead. This will also add virtual annotations to empty frames in the comparison results. [optional] if omitted the server will use the default value of False

Name Type Description Notes
id int [optional] [readonly]
task_id int [optional] [readonly]
target_metric bool, date, datetime, dict, float, int, list, str, none_type The primary metric used for quality estimation * accuracy - ACCURACY * precision - PRECISION * recall - RECALL [optional]
target_metric_threshold float Defines the minimal quality requirements in terms of the selected target metric. [optional]
max_validations_per_job int The maximum number of job validation attempts for the job assignee. The job can be automatically accepted if the job quality is above the required threshold, defined by the target threshold parameter. [optional]
iou_threshold float Used for distinction between matched / unmatched shapes [optional]
oks_sigma float Like IoU threshold, but for points. The percent of the bbox side, used as the radius of the circle around the GT point, where the checked point is expected to be. For boxes with different width and height, the "side" is computed as a geometric mean of the width and height. Read more: https://cocodataset.org/#keypoints-eval [optional]
point_size_base bool, date, datetime, dict, float, int, list, str, none_type When comparing point annotations (including both separate points and point groups), the OKS sigma parameter defines matching area for each GT point based to the object size. The point size base parameter allows to configure how to determine the object size. If image_size, the image size is used. Useful if each point annotation represents a separate object or boxes grouped with points do not represent object boundaries. If group_bbox_size, the object size is based on the point group bbox size. Useful if each point group represents an object or there is a bbox grouped with points, representing the object size. * image_size - IMAGE_SIZE * group_bbox_size - GROUP_BBOX_SIZE [optional]
line_thickness float Thickness of polylines, relatively to the (image area) ^ 0.5. The distance to the boundary around the GT line, inside of which the checked line points should be [optional]
low_overlap_threshold float Used for distinction between strong / weak (low_overlap) matches [optional]
compare_line_orientation bool Enables or disables polyline orientation comparison [optional]
line_orientation_threshold float The minimal gain in the GT IoU between the given and reversed line directions to consider the line inverted. Only used when the ‘compare_line_orientation’ parameter is true [optional]
compare_groups bool Enables or disables annotation group checks [optional]
group_match_threshold float Minimal IoU for groups to be considered matching. Only used when the ‘compare_groups’ parameter is true [optional]
check_covered_annotations bool Check for partially-covered annotations, useful in segmentation tasks [optional]
object_visibility_threshold float Minimal visible area percent of the spatial annotations (polygons, masks) for reporting covered annotations. Only used when the ‘object_visibility_threshold’ parameter is true [optional]
panoptic_comparison bool Use only the visible part of the masks and polygons in comparisons [optional]
compare_attributes bool Enables or disables annotation attribute comparison [optional]
match_empty_frames bool Count empty frames as matching. This affects target metrics like accuracy in cases there are no annotations. If disabled, frames without annotations are counted as not matching (accuracy is 0). If enabled, accuracy will be 1 instead. This will also add virtual annotations to empty frames in the comparison results. [optional] if omitted the server will use the default value of False

Answers to frequently asked questions

How to migrate data from CVAT.org to CVAT.ai

Please follow the export tasks and projects guide to download an archive with data which corresponds to your task or project. The backup for a project will have all tasks which are inside the project. Thus you don’t need to export them separately.

Please follow the import tasks and projects guide to upload your backup with a task or project to a CVAT instance.

See a quick demo below. It is really a simple process. If your data is huge, it may take some time. Please be patient.

Export and import backup demo

How to upgrade CVAT

Before upgrading, please follow the backup guide and backup all CVAT volumes.

Follow the upgrade guide.

Kibana app works, but no logs are displayed

Make sure there aren’t error messages from Elasticsearch:

docker logs cvat_elasticsearch

If you see errors like this:

lood stage disk watermark [95%] exceeded on [uMg9WI30QIOJxxJNDiIPgQ][uMg9WI3][/usr/share/elasticsearch/data/nodes/0] free: 116.5gb[4%], all indices on this node will be marked read-only

You should free up disk space or change the threshold, to do so check: Elasticsearch documentation.

How to change default CVAT hostname or port

To change the hostname, simply set the CVAT_HOST environemnt variable

export CVAT_HOST=<YOUR_HOSTNAME_OR_IP>

NOTE, if you’re using docker-compose with sudo to run CVAT, then please add the -E (or --preserve-env) flag to preserve the user environment variable which set above to take effect in your docker containers:

sudo -E docker-compose up -d

If you want to change the default web application port, change the ports part of traefik service configuration in docker-compose.yml

services:
  traefik:
    ...
    ...
    ports:
      - <YOUR_WEB_PORTAL_PORT>:8080
      - 8090:8090

Note that changing the port does not make sense if you are using HTTPS - port 443 is conventionally used for HTTPS connections, and is needed for Let’s Encrypt TLS challenge.

How to configure connected share folder on Windows

Follow the Docker manual and configure the directory that you want to use as a shared directory:

After that, it should be possible to use this directory as a CVAT share:

version: '3.3'

services:
  cvat:
    volumes:
      - cvat_share:/home/django/share:ro

volumes:
  cvat_share:
    driver_opts:
      type: none
      device: /d/my_cvat_share
      o: bind

How to make unassigned tasks not visible to all users

Set reduce_task_visibility variable to True.

Where are uploaded images/videos stored

The uploaded data is stored in the cvat_data docker volume:

volumes:
  - cvat_data:/home/django/data

Where are annotations stored

Annotations are stored in the PostgreSQL database. The database files are stored in the cvat_db docker volume:

volumes:
  - cvat_db:/var/lib/postgresql/data

How to mark job/task as completed

The status is set by the user in the Info window of the job annotation view. There are three types of status: annotation, validation or completed. The status of the job changes the progress bar of the task.

How to install CVAT on Windows 10 Home

Follow this guide.

I do not have the Analytics tab on the header section. How can I add analytics

You should build CVAT images with ‘Analytics’ component.

How to upload annotations to an entire task from UI when there are multiple jobs in the task

You can upload annotation for a multi-job task from the Dasboard view or the Task view. Uploading of annotation from the Annotation view only affects the current job.

How to specify multiple hostnames

To do this, you will need to edit traefik.http.<router>.cvat.rule docker label for both the cvat and cvat_ui services, like so (see the documentation on Traefik rules for more details):

  cvat:
    labels:
      - traefik.http.routers.cvat.rule=(Host(`example1.com`) || Host(`example2.com`)) &&
          PathPrefix(`/api/`, `/git/`, `/opencv/`, `/analytics/`, `/static/`, `/admin`, `/documentation/`, `/django-rq`)

  cvat_ui:
    labels:
      - traefik.http.routers.cvat-ui.rule=Host(`example1.com`) || Host(`example2.com`)

How to create a task with multiple jobs

Set the segment size when you create a new task, this option is available in the Advanced configuration section.

How to transfer CVAT to another machine

Follow the backup/restore guide.

How to load your own DL model into CVAT

See the information here in the Serverless tutorial.
