PHTrans: Parallelly Aggregating Global and Local Representations for Medical Image Segmentation

1 code implementation9 Mar 2022 Wentao Liu, Tong Tian, Weijin Xu, Huihua Yang, Xipeng Pan

In this paper, we propose a novel hybrid architecture for medical image segmentation called PHTrans, which parallelly hybridizes Transformer and CNN in main building blocks to produce hierarchical representations from global and local features and adaptively aggregate them, aiming to fully exploit their strengths to obtain better segmentation performance.
