Abstract :
The authors discuss the interaction of reflectance and illumination components in digital images. A first-order model relating reflectance and illumination is considered. Previous attempts to separate reflectance and illumination components are discussed, and research approaches in this area are discussed with reference to one example: the illumination-independent estimation of motion. Results highlight the importance of using processing methods which incorporate a spatial model of illumination
