Abstract
The utilization of color information to increase the accuracy of 3-D shapes derived from photometric stereo is described. Multicolored objects under white illumination are considered. Using color images rather than gray-scale makes it simple to separate the specular and diffuse reflection components. The diverse properties of diffusive and specular reflection yield supplementing constraints on the surface orientation, making the method less sensitive to noise
