Um método para a detecção da fóvea em imagens de fundo do olho através da correlação de modelos

Abstract

We propose a novel method for finding the fovea in colored images of the eye fundus. Unlike the existing literature, our method find out the location of the fovea through the use of images of real foveae template and the calculation of a correlation coefficient. The developed method is able to identify the region of the fovea images with and without lesions of diabetic retinopathy. In the experiments, we used the DIARETDB1 image database. This database contains images of the back of the eye, of which 84 of the 89 have lesions caused by diabetic retinopathy. Our evaluation indicates that the method is able to detect the region of the fovea on 82,02% of the tested images.
