Boundary Loss for Remote Sensing Imagery Semantic Segmentation

WebWidely used loss functions for convolutional neural network (CNN) segmentation, e.g., Dice or cross-entropy, are based on integrals (summations) over the segmentation regions. Unfortunately, it is quite common in medical image analysis to have highly unbalanced segmentations, where standard losses contain regional terms with values that differ … WebAug 2, 2024 · A tag already exists with the provided branch name.

The boundary loss, at its core, is a pixel-wise multiplication between the network predictions (the softmaxes), and a pre-computed distance map. Henceforth, a big chunk of the implementation happens at the data-loader level. The implementation has three key functions: 1. the boundary loss itself (BoundaryLoss … See more Core implementation (to integrate the boundary loss into your own code): 1. python3.5+ 2. pytorch 1.0+ 3. scipy (any version) To reproduce our experiments: 1. python3.9+ 2. … See more Extension to a 3D-CNN is trivial, one need only to pre-compute the 3D-distance map, and to sub-patch it in a traditionnal fashion. The code of the Boundary loss remains the same, … See more 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.
