Physically-based edge labeling
Terrance E. Boult, Lawrence B. Wolff · 2002
The authors present a physically based approach, using polarization, to distinguish three types of image edges; limb edges, specular edges, and albedo/physical edges. Assuming general imaging conditions and smooth dielectric surfaces, a labeling scheme which enables one to distinguish among these edge types has been developed. The method is demonstrated on laboratory images.>
