An automatic color correction method inspired by the retinex and opponent colors theories

Abstract

Color correction indicates the process of changing the colors of a digital image in order to reach given objectives. Usually the criteria under which color correction is performed match those of white-balancing and color constancy. In this work we present and automatic color correction method inspired by the Retinex and opponent colors theories with theoretical applicability on images with multiple illuminants. The method here presented has been tested in the field of skin tone color correction.
