Localization of Optic Cup-Disc in Retinal Images Using Morphological Filters for Glaucoma Detection

Glaucoma is one of the main diseases causing permanent blindness. It is marked by an increase in Intraocular Pressure (IOP) which results in changing the shape of Optic disc and Optic cup. Segmentation and Localization of Optic Disc and Optic Cup for the automated detection and diagnosis of Glaucoma is necessary. Morphological Filters with the method of thresholding of the retinal fundus images have been adapted for segmentation of Region of Interest (ROI). The quality measurement of the segmentation of the ROI can be determined by the use of Similarity Coefficients. The resultant segmented binary images have been obtained with the value of Dice and Jaccard representing overlapping and similarity check between the segmented image and the ground truth. Cup to Disc Ratio has been calculated for the temporary analysis of Glaucoma.
