摘要：In the framework of completely computer assisted diagnosis of glaucoma, an advanced algorithm thatidentifies the optic cup and optic disk, determines the radius by segmenting out the optic cup and disk and calculatesthe ratio of the optic cup to disk radius in fundus images of the macula is presented and discussed in this paper. Theparameters of thecup to disk ratio in the optic disk region of retina are hallmark of glaucoma detection and allowitsdetection with a high sensitivity. Since detection of the ratio of optic cup to disk radius is asignificant diagnostic task,a major role is being handled by the computer assistance. The optic disk has been found by using red color space imageas the optic disk is brighter considering to the other macula region and the contours are identified by means ofmorphological reconstruction techniques. The detection of optic cup has been done by using the green color spaceimage. The optic disc and the optic cup have been detected by means of thresholding and morphological reconstructiontechnique.
