Block Attention and Switchable Normalization Based Deep Learning Framework for Segmentation of Retinal Vessels

open access: yesIEEE Access, 2023
The presence of high blood sugar levels damages blood vessels and causes an eye condition called diabetic retinopathy. The ophthalmologist can detect this disease by looking at the variations in retinal blood vasculature.
