A faster MRF optimization based method for Shape from Shading using Gibbs sampling with quadruplet cliques

Abstract

This paper extends the MRF formulation approach developed in [7] and [6] for solving the shape from shading problem. Our method extends the Gibbs sampling approach to solve an MRF formulation which characterizes the Shape from Shading (SFS) problem under Lambertian reflectance conditions (the algorithm is extensible to other lighting models). Our method… (More)
