Ap. Petrov et Ll. Kontsevich, PROPERTIES OF COLOR IMAGES OF SURFACES UNDER MULTIPLE ILLUMINANTS, Journal of the Optical Society of America. A, Optics, image science,and vision., 11(10), 1994, pp. 2745-2749
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.
