Researchers have developed a novel wavelet-guided segmentation network called WaveSDG to address challenges in fundus image segmentation across different acquisition conditions. This method decouples anatomical structures from domain-specific appearances by decomposing images into wavelet sub-bands. A key component, the Wavelet-based Invariant Structure Extraction and Refinement (WISER) module, refines features to anchor global anatomy while enhancing edges and reducing noise. Evaluations on optic cup and disc segmentation demonstrated WaveSDG's superior performance and robustness compared to existing state-of-the-art methods. AI
