Abstract: "We propose an improved shape from shading (SFS) algorithm which is an extension of the recently published algorithm by Zheng and Chellappa [13]. A markedly more accurate estimate of the azimuth of the illumination source is presented. Depth reconstruction has been improved upon by using a new set of boundary conditions and adapting a more sophisticated technique for hierarchical implementation of the SFS algorithm. Errors at the boundaries of images and in rotation of the reconstructed images have been corrected. Typical results on synthetic and real images are presented."
