Abstract :
This paper presents segmentation of retinal features such as Optic Disc (OD) and blood vessels for screening the eye diseases. An optic disc is only the brightest region in retina through which blood vessels are entering and leaving from the eye. So that analyzing these features aids to diagnose various retinal diseases. First, the blood vessel features are segmented and it is classified using an ensemble classifier then the performance of the classifier is evaluated.Second, the fully automated segmentation algorithm localizes the Optic Disc (OD) using template matching. Then it is segmented using level set segmentation method and morphological filter is used to remove the artifacts other than the OD.
