Abstract
Gloss-based material classification of an object fabricated from an unknown material, particularly where the unknown material is one from a limited set of predetermined materials. The object is illuminated with an area light source such that the object is illuminated from multiple angles. An image of the object is obtained, and specular reflections from the object are measured by analyzing the image. The object material is classified based on a number of high-intensity specular reflections.
