Abstract
In this paper, we analyze the problem of recovering the shape of a smooth Lambertian surface from two images obtained by consecutive illumination of the surface by distant point light-sources from two different directions. We discuss the issues of existence and uniqueness of solutions to the corresponding system of two first-order non-linear partial differential equations. We show that generically this system has, up to a constant, a unique solution. We also examine exceptional cases for which there is no such uniqueness.
