摘要： CHARACTER AND PATTERN RECOGNITION MACHINE AND METHOD A pattern recognition system, particularly a handprint character recognition system in which electrical binary black/white "image" of one or more handprinted characters is formed and a plurality of centers of recognition (CORs) within said binary black/white images are selected as reference points for measuring the characteristic enclave of the black/white image immediately surrounding the CORs. A library of templates of said measurements around the CORs for a plurality of know exemplary character images is stored in a memory for comparison with corresponding measurements made around the CORs of images whose class is unknown to produce "template scores" proportional to the similarity of the enclaves of the know image to the enclaves measure by templates. The generic shape of a character in expressed as a "character equation" involving template scores developed on an unknown image, and each character equation is evaluated including comparing the values of such equations, and selecting the best value to determine the generic name of the unknown character.

摘要： CHARACTER AND PATTERN RECOGNITION MACHINE AND METHOD of The Disclosure Banking apparatus for reading numeric information on bank checks, drafts and like documents. An electronic black/white pixel image of the numeric information is analyzed by a system capable of reading unconstrained, constrained, printed and typed numeric characters, locating the division between dollar and cents amounts. The invention also reads overlapping, touching and not touching characters. A check is .fed (330) to a scanner (331) and converted to a black and white image. A courtesy amount field (CAF) on the check is located by a CAF locator (332) and is provided to a recognition system (333).
