Abstract :
This paper discusses the perceptual completion problem of 3-D scene within the framework of stereo vision. A model of perceptual completion based on electrostatic field, which referred to the laws of Gestalt psychology, the rules of visual organization and the properties of electrostatic field, was presented. In the model, stimuli were defined and arranged on the breakpoints of fragments to produce the field for completion. The field constructed by the model can match the breakpoints naturally and connect them with smooth curves. The completions of occluded boundaries and illusory contours agree with the perceptual results of human. The corresponding algorithm can be used for reconstructing 3-D information of a scene and segmenting the scene into a set of surfaces from stereo images.
