Toward accurate recovery of shape from shading under diffuse lighting
A. James Stewart, M.S. Langer · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1997
A new surface radiance model for diffuse lighting is presented which incorporates shadows, interreflections, and surface orientation. An algorithm is presented that uses this model to compute shape-from-shading under diffuse lighting. The algorithm is tested on both synthetic and real images, and is found to perform more accurately than the only previous algorithm for this problem.
