Publicación Acceso abierto Implementación y aplicación de algoritmos Retinex al preprocesamiento de imágenes de retinografía color(2014-04-24) Durango-Londoño, N. (Natalia); Bizai, G. (Gustavo); Drozdowicz, B. (Bartolomé)Diabetic retinopathy is a disease caused by complications of the retina, with progressive evolution. This pathology is detected on the fundus eye images, which in most cases have non-uniform illumination. In this paper four type of algorithms, based on the Retinex theory, were implemented and applied to fundus images in order to provide better illumination for later visualization or processing. The purpose was to find more accuracy to detect the presence or not of the disease and thus to get a more accurate approach of diagnosis.
