WebApr 23, 2024 · (with a few caveats. First off, it is normally done separately per class so you get an mAP value for each class, and secondly, mAP is done using bounding boxes with a set threshold of overlap to be considered a match, though theoretically could be done with pixel-wise IoU for a finer analysis). Reasons to use mAP: WebAug 10, 2024 · Simply put, the IoU is the area of overlap between the predicted segmentation and the ground truth divided by the area of union between the predicted segmentation and the ground truth, as shown on …

WebApr 13, 2024 · In general, the higher the number, the more accurate the segmentation is considered. Each image segmentation model has distinct characteristics, and the accuracy may vary for a specific class. Therefore, even if the average IoU is high, certain classes may have a lower IoU than other models. WebOct 25, 2024 · This is the precision-recall curve. In COCO they change the IoU values from 50% to 95%, at a step of 5%. So we end up with 10 precision-recall pairs. If we take the average of those 10 values, we get AP@[0.5:0.95]. Sometimes the IoU threshold is fixed, for example, at 50% or 75%, which are called AP50 and AP75, respectively.
