Abstract
This paper presents a novel technique to estimate illumination color in a scene. The key principle is that the blurred inter-reflection of a camera mounted “nose” represents the illumination color directly under weak scene assumptions. The nose surface profile is designed to reflect a blurred scene version into a small image area. The nose image is then spatially mapped to the scene image to correct its colors. Experiments showed that a nose surface represents illumination color robustly and as effective as a scene white patch with the merit of detecting smooth spatial changes of illumination color. The color constancy performance on real images is presented and compared with the retinex method [1].
