It is generally accepted that the process of figure/ground separation, which distinguishes spatially frontal regions and backward regions spreading behind the frontal regions in 3D space from the 2D retinal image, can be regarded as centered on the visual information processing. This study performed some psychophysical experiments and modeling researches aiming to reveal the mechanism of information processing of form channel laying the basis on the figure/ground separation. We found the relations between figure/ground separation and some visual functions such as contour integration, perceptual position of visible/invisible contour, and pattern recognition. In addition, we investigated the method generating models of the form channel automatically.
