ABSTRACT:
A character recognition system extracts character blocks to contain a minimum character unit therein. The character recognition system has the capability of re-combining and/or re-extracting character blocks during the character recognition process. Re-combination and re-extraction of the character blocks is controlled based on the history of the extraction process for each of the character blocks so that re-combination and re-extraction can be performed effectively.
