摘要
This article presents a method for shape recovery from color image in the case of a non-Lambertian surface illuminated by only a single light source. In the first step, we use the dichromatic reflection model and obtain the directions of spectral power distributions of the light due to surface reflection and body reflection by using eigenvectors of the moment matrix of the color signals. In the second step, the parameters determining the reflectance map are identified by using the dichromatic reflection model and information of the maximum intensity point. Subsequently. the surface normal of the object is estimated and the 3-D shape is recovered.
