SimilarityThresholdPolicy class reference

An IoU threshold policy for rectangle, polygon, mask, and ellipse requirements. The `iou_threshold` field also accepts a finite number between 0 and 1, such as `0.7`. Existing numeric thresholds are returned as numbers. A constant policy uses one threshold for all shapes: ```json {"type": "iou", "mode": "constant", "value": 0.7} ``` A linear policy chooses a threshold from the GT shape area in px²: ```json { "type": "iou", "mode": "linear", "input": "gt.shape_area", "extrapolation": "clamp", "points": [{"x": 100, "y": 0.4}, {"x": 1000, "y": 0.9}] } ``` Linear policies require 2-200 points with unique positive areas sorted in ascending order and thresholds between 0 and 1. Outside the curve, the nearest endpoint applies. Policies without `type` are accepted as IoU for compatibility; responses include it. Other threshold types are not supported. Setting a child's threshold to `null` restores inheritance of the whole threshold. Root requirements cannot inherit their threshold.
