Graph-Segmenter: Graph Transformer with Boundary-aware Attention for Semantic Segmentation

no code implementations15 Aug 2023 Zizhang Wu, Yuanzhu Gan, Tianhao Xu, Fan Wang

To address this issue, we propose a Graph-Segmenter, including a Graph Transformer and a Boundary-aware Attention module, which is an effective network for simultaneously modeling the more profound relation between windows in a global view and various pixels inside each window as a local one, and for substantial low-cost boundary adjustment.
