Affinity Feature Strengthening for Accurate, Complete and Robust Vessel Segmentation

1 code implementation12 Nov 2022 Tianyi Shi, Xiaohuan Ding, Wei Zhou, Feng Pan, Zengqiang Yan, Xiang Bai, Xin Yang

Vessel segmentation is crucial in many medical image applications, such as detecting coronary stenoses, retinal vessel diseases and brain aneurysms.

BATFormer: Towards Boundary-Aware Lightweight Transformer for Efficient Medical Image Segmentation

2 code implementations29 Jun 2022 Xian lin, Li Yu, Kwang-Ting Cheng, Zengqiang Yan

Specifically, to fully explore the benefits of transformers in long-range dependency establishment, a cross-scale global transformer (CGT) module is introduced to jointly utilize multiple small-scale feature maps for richer global features with lower computational complexity.
