Filed: 1988-11-12
Abstract: PURPOSE:To quickly recognize a rotated character by converting an extracted feature quantity in accordance with a rule corresponding to the angle of rotation of the character and collating the feature quantity after conversion with a dictionary. CONSTITUTION:The feature quantity is extracted from an input character by a feature extracting part 312 and converted in accordance with the angle of rotation of the character by a rotation histogram generating part, and the feature quantity after conversion is compared and collated with a dictionary 317. When the angle of rotation of the character is not preliminarily known in this case, the input character is recognized as characters rotated at two or more angles, and the angle of rotation of the character is determined in accordance with character recognition results. Thus, the rotating operation is not performed in the stage of a character image where the processing quantity for the rotated character is bulky, and only the dictionary corresponding to non-rotated characters is used to easily and quickly recognize the character, and this method can be used through the direction of rotation of the input character is not known.
