In binocular vision, interocularly unpaired points are often generated as a result of occlusions. These points can only produce false matches, and have no information about binocular disparities. However, recent psychophysical experiments have suggested that interocularly unpaired points play an important role in human stereo perception. This article introduces a stereo algorithm that can extract depth cues from not only interocularly paired but also unpaired points. Computer simulation demonstrates that our algorithm can correctly process the da Vinci stereogram as well as natural stereo pairs.
