GSCA-UNet: a gated spatial-channel attention U-net for accurate skin lesion segmentation

This work proposes GSCA-UNet (Gated Spatial-Channel Attention UNet), a novel segmentation architecture for skin lesions that consistently outperforms competitive baselines across multiple metrics and exhibits superior robustness on challenging cases with blurry borders, irregular shapes, and severe artifacts.
