Character recognition method, character recognition device, document image processing system and recording medium

摘要

PROBLEM TO BE SOLVED: To actualize a high-speed and high-precision character recognition module with high independency which uses a cache process. ;SOLUTION: A cache process part 108 of a character recognition module 102 basically saves the character coordinates and recognition result of a character image in a cache storage part 112 so as to reduce the storage capacity for caching, but stores some character image itself. When one recognition object area is specified and the character recognition module 102 is actuated, a document identity decision part 103 judges that a document image is not identical and discards the contents of the cache storage part 112 prior to the character recognizing process if the same image as a character image stored in the cache storage part 112 is not at the same position with the document image in a document image storage part 114.;COPYRIGHT: (C)2001,JPO
