Novel Technique Based on Pixel Level Snakes for Automated Retinal Vessel Segmentation and Vascular Feature Analysis for Detecting Retinal Abnormalities

Abstract

Recent studies suggest that changes or abnormalities found in human retinal vasculature have a strong correlation with various disorders such as cardiovascular diseases, hypertension, diabetes, stroke, and arteriosclerosis. So, the accurate extraction of retinal vasculature map is an important task for getting the information about these diseases. This retinal vasculature map is further used for the assessment of various retinal vascular attributes like length, diameter, width, tortuosity, and branching angle. Small changes in these vascular attributes may produce different pathological disorders which may further cause blindness. newline
