ABSTRACT:
Character recognition method and apparatus according to the present invention comprises the partial pattern dictionary which classifies and registers partial patterns of characters to be recognized in accordance with direction data of strokes and the partial pattern composition dictionary which classifies and registers dictionary characters in accordance with the partial patterns. When a character image to be recognized is inputted, each stroke is converted into direction data. The partial pattern dictionary is searched by using the attained direction data and divides the character image to be recognized into a single or plurality of partial patterns. The partial pattern composition dictionary is searched by using the partial patterns attained in the above-described way. A dictionary character is thus attained as the result of recognition.
