The photometric stereo technique (PS) has been used for shape recovery for quite some time now. Using a modification of the method, we can recover local surface normals and surface colour from multiple images for surfaces with unspecified reflectance function. However, for adequate recovery one should be able to detect and appropriately deal with shadows and highlights in the input images. We propose here a methodology that allows us to do that
