Volume perception in motion parallax

Volume Perception is considered as an important function in the human visual system. By now, the volume perception has been induced by binocular stereopsis and several monocular depth cues; it was confirmed that binocularly unpaired regions play an important role for the volume perception. In the present research, the volume perception could be obtained in the observation of moving objects with curved surface; appearing and disappearing parts (SDAD: successive disparity of appearing and disappearing) are considered as an indispensable factor for the volume perception in the motion parallax, which is compatible with binocular unpaired parts in stereposis.
