A Dual-Stage Deep Lesion Segmentation Framework with Gradient and Boundary Optimization for Diabetic Retinopathy Retinal Images

Diabetic Retinopathy (DR) is a leading global cause of preventable blindness, and the early detection and precise segmentation of pathologies play a key role in clinical decisions in this disease. Conventional deep learning models, however, suffer from the problem of weak lesion boundaries, gradient inconsistency, and...
