High speed detection of fundus optical disc

In this paper a fast method has been proposed for the detection of optical disc in retinal fundus image using mean intensity values, to be used in retinal image based person authentication system. The proposed method uses pixel intensity in green channel of RGB image and candidate based approach to detect optical disc location. Proposed system has been successfully tested on DRIVE, MESSIDOR, VARIA, VICAVR and DIARETDB_01 publicly available standard databases and produced 97.5%, 97.8%, 94%, 93.1% and 86.5% accuracy respectively.
