UCTransNet: Rethinking the Skip Connections in U-Net from a Channel-wise Perspective with Transformer. (arXiv:2109.04335v3 [cs.CV] UPDATED)

Web: http://arxiv.org/abs/2109.04335

Most recent semantic segmentation methods adopt a U-Net framework with an
encoder-decoder architecture. It is still challenging for U-Net with a simple
skip connection scheme to model the global multi-scale context: 1) Not each
skip connection setting is effective due to the issue of incompatible feature
sets of encoder and decoder stage, even some skip connection negatively
influence the segmentation performance; 2) The original U-Net is worse than the
one without any skip connection on some datasets. Based on our …
