WebI specifically want to get the AP/mAP values for object detection. All I know for sure is: Recall = TP/ (TP + FN), Precision = TP/ (TP + FP) For example, if I only have 1 class to evaluate, and say 500 test images. Each test image may have different number of predictions (bounding box proposals) but each image only has one ground-truth … WebNote that the IoU is 0.0 when there is a 0% overlap between the predicted and ground-truth boxes. The IoU is 1.0 when the 2 boxes fit each other 100%. To calculate the IoU for an image, here is a function named intersection_over_union(). It accepts the following 2 parameters: gt_box: Ground-truth bounding box. pred_box: Predicted bounding box.
