Abstract

To enhance the segmentation accuracy of the optic disc and optic cup and assist in the early diagnosis of glaucoma, an improved deep separable multi-scale aggregation network based on the U-Net architecture (Depthwise Separable Multi-scale Aggregation Network, DSMA-Net) is proposed. First, an adaptive separable multi-scale attention module is introduced to enhance feature representation and effectively capture the complex structures of the optic disc and cup, thereby reducing boundary blurring. Second, some traditional convolutions in the network are replaced with depthwise separable convolutions to reduce computational complexity and improve model efficiency. Additionally, an improved adaptive weighted Tversky loss function is used to focus the network on optic disc and cup pixels, alleviating the dominance of background pixels and further improving segmentation accuracy. Experimental results show that DSMA-Net has significant advantages in optic disc and cup segmentation tasks on the DRISHTI-GS, RIM-ONE-R3, and ORIGA datasets, providing strong technical support for early glaucoma diagnosis.
