ABSTRACT

A child upon seeing a cat for the first time, and being told by her parents what it is called, creates an image with the prime features of fur, four legs, a long tail, pointy ears, big round eyes, whiskers, and a small pink triangular nose, all arranged in an appealing configuration. In computer vision, light reflected from object is picked up by a camera's lens and transmitted through an optic nerve-like relay to retina-like photodetectors that convert light to proportional electrical signals. The array of pixels is represented in a computer as a two-dimensional matrix of pixels of different light intensity with a third dimension holding the primary colors typically red, green, blue in proportions that can together generate any color, much like a television camera does in reproducing images on a liquid crystal display screen. Depth perception is gained by two separated cameras for stereographic imaging, but this requires correlation of the corresponding points of each detector's image.
