An optic disk and vessel Segmentation, location is a very essential task for retinal image analysis. This research gives automated method for segmentation of the optic disc in retinal images using otsu’s thresholding and boundary extraction. First, the true colour Retinal images are converted to gray image and then image is enhanced using histogram equalization. This improves the efficiency of the conventional otsu’s thresholding method. The proposed method of segmentation utilizes gray level thresholding for segmentation and then morphological operators and thresholding are used for extracting the optical disk and blood vessel. The method is tested on the different optical disc images. The method is less complex and efficiently recognizes the boundary of the optic disc and also evaluates the blood vessel. The optical canters are tabulated for original and fudus images.
