Transformers, equipped with self-attention mechanisms, aim to address this problem. However, in medical image segmentation it is beneficial to merge both local and global features to effectively integrate feature maps across various scales, capturing both detailed features and broader semantic elements ...
As an advanced non-U-shaped architecture model, Swin Transformer leverages a hierarchical Transformer architecture and a shifted window self-attention mechanism, which offers advantages in capturing multi-scale information. However, in our experiments, the performance of Swin Transformer did not surpass ...
In this work, a multi-scale global attention network is proposed, the structure of the MGA-Net is shown in Fig. 2, which includes three parts: backbone network, GCA block and AG block. To enhance the feature representation ability, an effective backbone network is designed for feature extract...
