WebA.1 More details on boundary IoU loss Intersection over Union (IoU) is the standard evaluation metric for segmentation (e.g., image segmentation) and detection tasks (e.g., object detection and temporal action detection). Given a number of predictions it measures what are true positives and false positives against the ground-truth. WebAug 12, 2024 · In this case, the IoU score is 1 and optimal. On the other hand, if the predicted mask is shifted or changed in size compared to the original mask, then the union gets bigger than the intersection. The IoU score decreases. Regarding the street sign example again, with 10% of an image showing a street sign and the residual area is just …
