A SYSTEMATIC METHOD FOR CHARACTER RECOGNITION

Abstract

A technique for character recognition is described which possesses several characteristics necessary for satisfactory recognition. The desirable characteristics are: (1) each character is representable by a unique mathematical expression; (2) the recognition technique is independent of character size; (3) the technique is independent of character orientation; and (4) the gross features of a character are identified by using only a limited number of terms of the mathematical expression. The principal disadvantage of the technique is that it is sensitive to irregularities or distortions of standard figures. The technique is considered feasible for the recognition of typed letters or numbers, where the figures are distinct and are identical for each appearance. Hand written letters and words are not adaptive to this technique because of the immense number of standard characteristics which would be necessary.
