Highlight disparity contributes to the authenticity and strength of perceived glossiness.

摘要: The disparity of highlights on specular reflecting surfaces usually differs from the surface points. A. Kirschmann (1895) proposed that this fact may be used as a binocular cue for gloss perception. This was confirmed by Blake and H. Bulthoff (1990) who found subjects judged glossiness convex ellipsoidal most realistic if close to physical correct one. Extending finding, we investigate more closely whether effect highlight depends sharpness relative amount diffuse reflection. We measured both perceived strength authenticity gloss. complex, three-dimensional curved were stereoscopically presented CRT. reflection characteristics varied using Phong lighting model. Highlights either with or without disparity. In rating experiment, asked judge glossiness. presence lead an enhancement latter finding in additional matching experiment.
