Abstract
In this paper we propose a simple and effective way to improve the classical Shape from Shading (SFS) problem exploiting light projection information contained in the image data. Edges of concave regions can be split in projecting and the projected points. The geometrical relation between these points allows us to introduce a constraint on the SFS solution. To show the potentialities of our model, we present an application to a Cultural Heritage problem such as the extraction of the boundaries of the degradation zones. (C) 2004 IMACS.
