WHY COLOR CONSTANCY IMPROVES FOR MOVING OBJECTS

Marc Ebner

Abstract

Light which is measured by retinal receptors varies with the illuminant. However, a human observer is able to discount the illuminant and to accurately determine the color of objects. The human brain computes a color constant descriptor which is approximately independent of the illuminant. This ability is called color constancy. Recently, it has been shown that color constancy improves for a moving stimulus. It has been argued that high level motion areas may have an influence on the computation of a color constant descriptor. We have developed a computational model for color perception which can be mapped to the different stages of the human visual system. We test our model with two types of stimuli: stationary and moving. In our model, color constancy is computed purely bottom up. Our model also shows better color constancy for a moving stimulus. This indicates that an influence from high level motion areas is not required.
