A ROBUST DISCRETE APPROACH FOR SHAPE FROM SHADING AND PHOTOMETRIC STEREO
Bertrand Kerautret · Kluwer Academic Publishers eBooks · 2006
We present a discrete approach for solving the Shape From Shading problem. This approach allows us to recover directly the depth of the surface and is based on the propagation of equal height regions. The reconstruction can use more than one light source direction and can resolve the concave/convex ambiguity when only one source image is available. Moreover the robustness to noise is demonstrated on both synthetic and real images.
