概要

Computer vision first emerged as a sub-area of artificial intelligence, of which goal is building artificial life-forms with computers. Computer vision, for building input systems of such artificial life-forms, aims to establish computational models that allow machines to perceive the external 3D world in ways similar to human visual systems. Because humans utilize their eyes as sensors for this purpose, computer-vision researchers initially developed solutions that used passive sensors similar to human eyes (ie, television cameras) as input devices. Although the external world surrounding us is 3D, the images projected on each retina or a mechanical imaging device is 2D. In either system, one-dimensional reduction occurs. People learn to perceive 3D by augmenting this reduction using the so-called “common sense,” developed through the evolution and learning process. During the development of computer-vision …
