Abstract
The paper proposes an improved optic disc localisation method in color retinal images. First, the optic disc area in retinal images of any dimensions is identified. Then the method iteratively extracts the optic disc edges and obtains a circular optic disc boundary approximation by a Hough transform. However this is a first step of a retinal image analysis project which will be completed later with other tasks. The final goal is to detect in early stages signs of ophthalmic pathologies by successive analysis of ophthalmoscopy images.
