Iou-balanced loss

WebBelow is the definition of IOU-balanced loss. IOU = TP/(TP+FP+FN) Boundary loss Boundary loss is that of a form of distance metrics on a space of contours, not regions. It, therefore, solved the issue of highly imbalanced segmentations because it uses integrals over the interface between regions instead of unbalanced integrals over the regions. Webinstability of IoU loss function. In addition, the experimental results on the PASCAL VOC2012 dataset reveal that our method effectively improves the segmentation accuracy of the network and attains significant improvements beyond state-of-the-art IoU loss function methods.
