dc.description.abstract Main objective of segmenting image is to convert the representation of an image into another format that is useful for analysis of image features and properties. Retinal image segmentation is an essential stage for retinal disease analysis and identification. Retinal image segmentation helps the ophthalmologists in detection of glaucoma eye disease. Glaucoma eye disease is one of the important causes for permanent vision loss. Early detection of glaucoma is important in order to prevent further progression of vision loss. Vertical cup-to-disc ratio is the important clinical parameter used for glaucoma disease detection and accurate segmentation of optic disc from retinal images is of great significance. This work presents three methods based on Thresholding for segmentation of optic disc region from retinal fundus images. The proposed methods were evaluated using DRIONS-DB dataset containing 110 images and HRF dataset containing 45 images. The performance metric boundary localization error is calculated by comparing each proposed method with the ground truth values. Results from the proposed methods shows that methods are less complex and efficiently works on all images. en_US
