matlab source code for optic disc segmentation

Abstract

Glaucoma is the second leading cause of loss of vision in the world. Examining the head of optic nerve (cup-to-disc ratio) is very important for diagnosing glaucoma and for patient monitoring after diagnosis. Images of optic disc and optic cup are acquired by fundus camera as well as Optical Coherence Tomography. The optic disc and optic cup segmentation techniques are used to isolate the relevant parts of the retinal image and to calculate the cup-to-disc ratio. The main objective of th ....etc

matlab code for retinal image optic disc extraction

Abstract

In this article, we propose a new method for localizing optic disc in retinal images. Localizing the optic disc and its center is the first step of most vessel segmentation, disease diagnostic, and retinal recognition algorithms. We use optic disc of the first four retinal images in DRIVE dataset to extract the histograms of each color component. Then, we calculate the average of histograms for each color as template for localizing the center of optic disc. The DRIVE, STARE, and a l ....etc

matlab code for optic disc localization

ABSTRACT

This paper presents a novel approach to the fast localization and extraction of optic disc from fundus images of the human retina. Optic disc continues to be a major landmark for fundus image registration and is indispensible for the understanding of retinal fundus images. For the detection of optic disc, we first decompose the image into its bit planes. The lower order bit planes are found to carry important information of the location of optic disc. Then we find the exact location by means of ....etc

ABSTRACT

Retinal vessel segmentation is an essential step for the diagnoses of various eye diseases. An

automated tool for blood vessel segmentation is useful to eye specialists for purpose of patient screening and clinical study. Vascular

Biometrics are automated methods of recognizing a person based on a physiological or behavioral characteristics (fingerprint, iris, voice recognition etc.) Among them one of the most
effective biometric technology is the blood vessel recognition of ocular fundus, especially the retina. Personal identification using retinal scans is composed of three principal modules: blood
vessel segmentation, feature extraction, and feature matching. Due to the technological limitations in manufacturing low-cost retinal scanners, there were few works publis ....etc
