On the research work leading to automatic analysis of retinal images, the knowledge of the optic disc (OD) location is essential, and a new method to locate the optic disc automatically is proposed. We propose an algorithm for the detection of OD in the retina which takes advantage of the powerful preprocessing techniques such as the contrast enhancement, Gabor wavelet transform, mathematical morphology and Earth Mover’s distance as the matching process. Forty images of the retina from the DRIVE database were used to evaluate the performance of the method.engEarth mover’s distanceGabor wavelet transformOptic disc detectionRetinal imagesconference object10.5220/0003766103560359
