Abstract

This paper describes a new approach to the shape from shading problem, using loopy belief propagation which is simple and intuitive. The algorithm is called Loopy Belief Propagation Shape-From-Shading (LBP-SFS). It produces reasonable results on real and synthetic data, and surface information from sources other than the image (eg range or stereo data) can be readily incorporated as prior information about the surface elevation at any point, using this framework. In addition, this algorithm proves the use of linear interpolation at the message passing level within a loopy Bayesian network, which to the authors’ knowledge has not been previously explored.
