The fast marching method has recently been applied to the shape from shading problem for orthographic projection [4]. Unlike many previous researches, the method is stable and monotone, and offer a well posed solution to the shape from shading problem. In this paper, the method is extended to perspective projection using a model that accounts for the foreshortening effect of perspective projection. Experimental results on synthetic images are also reported. A simple and practical method is also presented which generates realistic synthetic testing images under perspective projection.
