    Applying a Set of Gabor Filter to 2D-Retinal Fundus Image to Detect the Optic Nerve Head (ONH)
    Author(s): Rached Belgacem*, Hédi Trabelsi, Ines Malek and Imed Jabri

    Background: The detection of edge of the cup (excavation), disc, and the optic nerves head which converges into the center of the excavation in the papilla of the retina is a crucial procedure in computer vision object detection processing and analysis. Purpose: We propose a method and approach for cup and disc detection based on 2-D Gabor filter with the addition of some constraints. This paper approves that edge magnitude and edge phase are useful for extracting the disc and the cup and to overcome the lack contrast between the cup-disc in order to discriminate one from the other and to extract the different optical vessels along several directions theta. These methods are based on space image and phase image after searching the favorable parameters (Scale, sigma, a & b, r ...) to properly adjust the results of the a.. Read More»
