ABSTRACT:
An optical character recognition method and system adjusts positional, rotational and scaling differences between an input form image and a standard form image based upon selected corresponding portions of the two images prior to optically recognizing characters in predetermined areas of the input form. The corresponding portions include a predetermined mark such as a cross-line portions and or predetermined characters, and a selection process of these corresponding portions eliminates unlikely pairs of the corresponding portions based upon a distribution histogram analysis.
