Abstract
We present a theoretical framework for object-based segmentation of co lor images that extracts the uniformly colored regions on an arbitrary surface all the points of which are exposed to the same set of light sources. This segmentation is a necessary stage before shape-from-shad ing processing. We introduce a consistent definition of rank and provi de a complete classification of interactions among shape, surface colo r, and illumination. The proposed theory is an extension of known appr oaches.
