RetinaCAD - retinal computer-aided diagnosis system

Abstract

This paper presents an automatic application that provides several retinalimage analysis functionalities, namely vessel segmentation, vesselwidth estimation, artery/vein classification and optic disc segmentation. Apipeline of these methods allows the computation of important vessel relatedindexes, namely the Central Retinal Arteriolar Equivalent (CRAE),Central Retinal Venular Equivalent (CRVE) and Arteriolar-to-Venular Ratio(AVR), as well as various geometrical features associated with vesselbifurcations
