Abstract

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 known 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 known image to the enclaves measured by templates. The generic shape of a character is 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.
