1. In a hand print character recognition system comprising,(a) means for creating an electrical binary black/white "image" of one or more hand printed characters,(b) means for selecting a plurality of centers of recognition (CORs) within said binary black/white image as reference points and measuring the characteristic enclave of the black/white image immediately surrounding the CORs,(c) means for storing a library of templates of said measurements around the CORs for a plurality of known exemplary character images,(d) means for comparing said library of templates to 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 known image to the enclaves measured by templates,(e) means for expressing the generic shape of a character as being a "character equation" involving template scores developed on an unknown image, and(f) means for evaluating each character equation, including comparing the values of such equations, and selecting the best value to determine the generic name of the unknown character.
