Abstract: This paper presents an algorithm of shape from shading with variable albedo.The algorithm cancels the effect brought by the assumption that object surface only has single albedo in SFS traditional algorithms.First this paper makes use of a local albedo estimation method to compute the albedo for each pixel of an image and gains an albedo image.Next the paper segments the albedo image into several regions with uniform albedo values.And it writes up the algorithm of shape from shading with variable albedo.Finally,this paper presents two sets of experiments based on aforementioned theory.The experiments show that the method is modified and compared with traditional method,it extends the application range of SFS.
