What is the set of images of an object under all possible illumination conditions ? by BELHUMEUR, P. N, KRIEGMAN, D. J

“…The appearance of an object depends on both the viewpoint from which it is observed and the light sources by which it is illuminated. If the appearance of two…”

Efficient region tracking with parametric models of geometry and illumination by Hager, G.D., Belhumeur, P.N.

“…As an object moves through the field of view of a camera, the images of the object may change dramatically. This is not simply due to the translation of the…”

The Bas-Relief Ambiguity by Belhumeur, Peter N, Kriegman, David J, Yuille, Alan L

“…When an unknown object with Lambertian reflectance is viewed orthographically, there is an implicit ambiguity in determining its 3-d structure: we show that…”
