Abstract
A technique is presented which utilizes the polarization
properties of reflected light to separate specular and diffuse
components of reflection. This technique works for both dielectric and
metal surfaces, regardless of the color of the illuminating light source
or the color detail on the object surface. In addition to separating out
diffuse and specular components of reflection, the technique can also
identify whether certain image regions correspond to a dielectric or
metal object surface. Extensive experimentation is presented for a
variety of dielectric and metal surfaces, both polished and rough, using
a point light source
