Shape From Shading

A classic problem in computer vision is to compute the shape of an object from its grey-scale image. We're treating the interesting and relatively unexplored case of a terrain under diffuse lighting, as might occur on an overcast day. The input consists of a greyscale image I(x,y) and the output consists of a depth map z(x,y).

This is joint work with Michael Langer of NEC Research.

We make the following assumptions:
