ABSTRACT:
A character recognition method which accurately recognizes characters contacting or adjacent to a ruled line. Black runs each having a length greater than a predetermined length are extracted from the original binary image. A ruled line rectangle defined by adjacent black runs is extracted from among the extracted black runs so that the ruled line rectangle completely encircles the adjacent black runs which are within a predetermined short distance from each other. Black pixels contained in the ruled line rectangle are deleted from the original binary image. Then, a recognition is performed for characters contained in the original binary image.
