WebbIn computer vision, shape recovery is a classic problem. It aims to reconstruct a 3D shape from one or more intensity images. Such techniques are collectively known as Shape-from-X, where X includes shading, stereo, motion, texture, etc. Shape from shading (SfS) uses the pattern of lights and shades in a single image to infer the shape of the surface in view.
