TL;DR: In this paper, a neural network model based on the anatomy and physiology of the visual projection from the retina to V4 was developed to determine the surface reflectance of an object independent of the illuminant.
Abstract: To determine the surface reflectance of an object independent of the illuminant, a system must use the spatiochromatic context of the image. The authors have developed a neural network model based on the anatomy and physiology of the visual projection from the retina to V4. The network combines color-opponent and contrast information to achieve a good degree of color constancy. This network has been tested on simulated images corresponding to the stimuli used in well established psychophysical experiments. Responses qualitatively matched human responses to a variety of center-surround and Mondrian test stimuli. >
