Abstract:
An image recognition system for recognizing a target having a color and a pattern, comprising:(a) a display screen formed with a plurality of pixels for displaying an image including a target and its background, using a CCD camera;(b) an active eye system comprising:(i) a plurality of cursor-like movable sections, denoted as active eyes, indicated on the display screen using a portion of the pixels, each active eye being a closed frame defined on the display screen and being programmed to obtain color data from the area enclosed within the frame, said active eyes being movable on the display screen under predetermined rules to move each active eye to a boundary of a region, denoted as a colony, where a color within the closed frame of the active eye matches the color of the target pre-stored in a memory;(ii) a pattern recognition unit for recognizing a shape of the colony which is formed when connecting plural active eyes located along the boundary of the colony, wherein if the recognized shape does not match the pattern of the target pre-stored in a memory, each active eye moves until the pattern of the target in the memory is recognized; and(iii) a location calculation unit programmed to calculate the coordinates of the recognized pattern of the target based on coordinates of the active eyes; and(c) a pretreatment unit, which transfers a RGB system of a color from the CCD camera into a combination of hue, saturation, and brightness, and which compares the combination of hue, saturation, and brightness with the color data of the target in the memory, thereby outputting a value indicating the likelihood of color image in each active eye matching the target.
