DyGLNet: Hybrid Global-Local Feature Fusion with Dynamic Upsampling for Medical Image Segmentation
Summary
This paper proposes DyGLNet, a model that fuses global and local features using a hybrid feature extraction module and dynamic adaptive upsampling to improve medical image segmentation accuracy and efficiency. It addresses challenges like multi-scale lesion variability and ill-defined tissue boundaries while reducing computational overhead. Experiments on seven public datasets show superior boundary accuracy and small-object segmentation compared to existing methods.
