Abstract: Visual completion is constantly used by the visual system to deal with image data that is missing, ambiguous or corrupted. In recent years, there have been a large number of researches on visual completion. Although many researches reported that visual completion is based on Gestalt law in a common depth surface, little is known about the visual completion process among different depth surfaces. In this study fragments of Chinese characters were used to investigate the effects of binocular disparity, color and occlusion in visual completion. The results indicated that binocular disparity and color hinder the visual completion process. Occlusion facilitates global visual integration, and that global visual integration may inhibit those separation effects when high-level perceptual processing is involved under such occlusion conditions.

Key words: visual completion, binocular disparity, occlusion, perceptual filling-in
