Boundary loss for highly unbalanced segmentation

Webboundary loss can mitigate the issues related to regional losses in highly un-balanced segmentation problems. Rather than using unbalanced integrals over the regions, a boundary loss uses integrals over the boundary (interface) be-tween the regions. Furthermore, it provides information that is complementary to regional losses. WebMay 20, 2024 · CNNs for semantic segmentation typically use such loss functions as cross-entropy, dice score and direct I o U optimization while training the network, but they are not sensitive enough to some misalignment of boundaries. Even being deviated from the ground truth by 5-10 pixels, predicted boundary does not significantly contribute to the value of … WebAug 22, 2024 · Boundary-based loss, a recent new type of loss function, aims to minimize the distance between ground truth and predicted segmentation. ...
