ABSTRACT:
A code sequence matching method adapted to pattern recognition of characters compares one code selected from an unknown code sequence which is extracted from an input pattern with one code selected from a reference code sequence. The reference code sequence comprises one or more special codes for controlling an order of comparison between the codes of the unknown and reference code sequences. Then, selecting of the codes from the unknown and reference code sequences is carried out in accordance with the special codes.
