Attention points and 3-D surface perception with binocular viewing

With the binocular viewing, human visual system can perceive the 3-D features of an object from the disparity between two eyes and so on. Concerning some 3-D illusions, fuzziness phenomena in form perception for the same object with binocular viewing were found. One of them is the fuzziness of a surface depth perception from its boundary. The other is the bistable shape switching of an object from its contour. When the attention depth or attention points were changed in binocular viewing, surface depth or the object shape can be perceived as various form for entirely the same surface boundary or object contour, These fuzziness are concern the surface perception, surface interpolation and the object shape reconstruction. Probably, the attention point plays one of the important clues for these perception
