METHOD AND DEVICE FOR RECOGNIZING CHARACTER

摘要

PROBLEM TO BE SOLVED: To detect a character having the possibility of erroneous recognition by finding the reliability of the recognized result while using the relation of character form feature amounts between the concerned character and the other character. SOLUTION: The same character type block extracting part 6 classifies inputted character images into the groups of characters with the same character types and for each block, a character type feature amount extracting part 7 extracts the character type feature amount. Concerning the combination of all the characters in the same character type block, a similarity calculating part 8 calculates the similarity of character type feature amounts and a similarity discriminating part 9 compares the similarity found by the similarity calculating part 8 with a predetermined threshold value and stores the result in a similarity information recording part 10. Concerning each character in the group of characters judged as the same character type, an erroneous recognition detecting part 11 calculates the score while using specified information provided from the relation between the similarity of character types of characters and the recognized result. Thus, the high-reliability score can be defined while considering the relation with the other character and a reject character can be determined.
