Evaluating Object Detection Models: Guide to Performance Metrics

WebIn object detection, an intersection over union (IoU) threshold is required to define positives and negatives. An object detector, trained with low IoU threshold, e.g. 0.5, usually produces noisy detections. However, detection performance tends to … Web11 jul. 2024 · Left: RetinaNet employs a ﬁxed IoU threshold of 0.5 to select the positive anchors. If the IoU between the anchor (red box) and the ground truth (green box) is larger than 0.5, the anchor is denoted as positive to the ground truth. Middle: ATSS calculates the adaptive IoU thresholds based on the distribution of the anchors for each ground truth.
