Optical illusion seems to be the phenomena which are purely reflecting the mechanism of.human visual system and are expected as the effective cues to elucidating human visual mechanism. The author found the new types of 3-D visual illusion with binocular viewing. From the visual stimuli of binocular disparity given only along the contour of an object, human visual system can perceive entire 3-D illusory object where there are no physical visual stimuli giving depth information. They have close relation with the 3-D space perceiving functions in the human visual system. A study on these newly found optical illusions are introduced and the considerations are made for their applications and the exploitations including the contributions of information processing techniques such as computer graphics, computer vision and so on.

Human Visual Mechanism

Human beings obtain big amount of information from the external world through their visual system. Automated system such as robot must provide the visual functions for their flexible operations in 3-D circumstances. In order to realize the visual function artificially, we would be better to learn from the human visual mechanism. Optical illusions would be a pure reflection of the human visual mechanism; they can be used for investigating human visual mechanism. New types of optical illusion with binocular viewing are introduced and investigated.

New Paradigm

The human visual system can perceive 3-D information of an object by using disparity between two eyes, gradient of illumination (shading), occlusion, textures and their perspective and so on. Consequently, the disparity and the occlusion observed with binocular viewing seems to be the most important cues to get 3-D information. For the artificial realization of the visual function such as in computer vision or robot vision system, it seems to be a clever way to learn from the human visual mechanism. Recently, the author found a new type of illusion. When the visual stimuli of disparity are given only partially along the contour of an object, human visual system can perceive the 3-D surface (not only plane but also curved) of the object where there are no physical visual stimuli to get depth information. The interactions between the perceived illusory surface (occlusion, intersection and transparency) can be recognized. These newly found illusory phenomena have close relations with the visual function of 3-D space perception and can provide a new paradigm in the field of computer vision and human interface.

The article adduces the various aspects of the impact of a computer monitor on the functioning of the human visual system. A significant flow of information which daily receives visual apparatus person with computer screens accompanied not only asthenopia but also objective changes of the visual system. There was analysed the visual features and the factors that determined the occurrence of changes in the refractive computer users.

AbstractThe human visual system was shaped through natural evolution. We have used artificial evolution to investigate whether depth information and optical flow are helpful for visual control. Our experiments were carried out in simulation. The task was controlling a simulated racing car. We have used The Open Racing Car Simulator for our experiments. Genetic programming was used to evolve visual algorithms that transform input images (color, optical flow, or depth information) to control commands for a simulated racing car. We found that significantly better solutions were found when color, depth, and optical flow were available as input together compared with color, depth, or optical flow alone.
