Enhancement of glossiness perception by retinal-image motion: additional effect of head-yoked motion parallax.

It has been argued that when an observer moves, a contingent retinal-image motion of a stimulus would strengthen the perceived glossiness. This would be attributed to the veridical perception of three-dimensional structure by motion parallax. However, it has not been investigated whether the effect...
