Paper Abstract

A noel approach to reconstruct shape from shading information is presented, which considers both the global and local shading. Firstly, a 2D gray-level image is divided into several simple patches with snake model. Secondly, the shape of the patches is reconstructed respectively. Thirdly, the different patches are jointed into a whole one. And at last, the mosaic surface is smoothed. According to this method, not only the distortion caused by image discontinuity but also the effects of local noises is eliminated. Results of experiments are given to illustrate the usefulness of the approach.
