Intersection over Union (IoU) for object detection

Webto determine positive samples is to use Intersection-over-Union (IoU) between an anchor and a ground truth (GT) bounding box. For each GT box, one or more anchors are assigned as positive samples if its IoU with the GT box exceeds a certain threshold. Target values for both classi cation and localization (i.e. WebJun 1, 2024 · Firstly, when IoU is used to assign targets, only one anchor can be assigned to the truth box for the majority of slender objects. RetinaNet uses an IoU threshold (0.4, 0.5) to classify examples as positive or negative. When the IoU between an anchor and the closest truth box is less than 0.4, the anchor is considered a negative example.
