In this paper we analyze a speci c problem within the context of recovering the geometric shape of an unknown surface frommultiple noisy shading patterns generated by consecutive parallel illuminations by di erent light-sources. Shading-based single-view shape recovery in computer vision often leads to vector elds (i.e. estimated surface normals) which have to be integrated for calculations of height or depth maps. We present an algorithm for enforcing the integrability condition of a given non… CONTINUE READING
