Abstract

From the visual stimuli of disparity given for occluded objects only partially along the contour of an occluding object which is not physically depicted, the human visual system can perceive an entire 3-D illusory occluding object. There are several new findings concerning this illusion: an interaction between several illusory objects; an edge line perceived as an intersection of two illusory surfaces; an occlusion between illusory objects; and a transparency which is unique for binocular fusion. Two types of occlusion cues for 3-D perception are postulated and investigated. In further investigations of these illusions with motion, the author found new types of visual effects, which are named as `dynamic illusion' and could not be expected from the stational case. These newly found illusory phenomena have close relations with the visual functions of the 3-D space perception and can propose new subjects not only in the field of psychophysics and neuro-physiology but also artificial neural networks and computer vision.
