WebbThe Shape-From-Shading (SFS) problem is a fundamental and classical problem in computer vision. It is the process of computing three dimensional shape of a surface using its shading information from single image. In this paper, a new method for interactive shape from shading for reconstruction of a 3D shape is presented.
