ABSTRACT:
A character recognition apparatus and method for recognizing an unknown character by comparing strokes of the input character with stroke information stored in a dictionary. Each stroke of the input character is classified into one of plural categories according to stroke direction. The classified input strokes are rearranged into groups of strokes having the same classification. The degree of analogy between rearranged input strokes and stroke information stored in the dictionary for each group of similarly classified stroke group is calculated based on stroke length, and a maximum analogous element for each input stroke according to the calculated degree of analogy is detected. The detected maximum analogous elements are summed together, and the character whose sum is maximum is output as the identity of the unknown input character.
