Abstract

In the automatic analysis of retinal images for diagnosing various eye diseases such as diabetic retinopathy, glaucoma etc. the automatic detection of the optic disc is a crucial step. Before processing the fundus image for detecting any type of retinal disease it is necessary to mask out the anatomical features of eye so that they will not be mistaken as abnormality. Optic disc often considered as a bright lesion if not segmented out and results in false positives that affect the final results, therefore it is crucial to detect the optic disc. In this paper, a review of various methods for localizing and detecting optic disc along with their merits and demerits is presented.
