Cup-To-Disc Ratio Of The Optic Disc By Image Analysis To Assist Diagnosis Of Glaucoma Risk And Evolution

摘要

This work builds an image analysis algorithm to give assistance in the cup to disc ratio estimation of glaucomatous eyes. Often the contours of both the optic cup and disc are faint and intersected by entangled veins that make it difficult to draw their silhouettes. The algorithm, which takes into account the viewing conditions of the specialist, is based on the information of color, the color differences between neighbor pixels and the geometry of the areas involved.
