| Abstract | Shape from Shading is one of the methods used for shape recovery which exploits the fact that surface patches, having different inclination relative to a light source are imaged with different brightness. In order to solve the DTM reconstruction problem by SFS the image formation process has to be modeled and eventually inverted with respect to the parameters describing the object surface. Surface reflectance can be exactly described by its bi-directional distribution function (BDRF). In this paper we show that there exist images that could not have arisen from shading on the smooth surface with uniform reflecting properties. This means that the gray shade values are also significantly influenced by the other factors, which have not been included into SFS functional model. |
