CHARACTER RECOGNITION DEVICE, CHARACTER RECOGNITION PROGRAM AND CHARACTER RECOGNITION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a character recognition device and the like for correctly performing character recognition. SOLUTION: The character recognition device 100 calculates a certainty factor as a classifying part 162 performs character recognition of an input image, and specifies a character region and a character region with noise on the basis of the calculated certainty. A temporary line candidate position estimating part 163 and a line rectangle correcting part 164 specify a temporary line candidate rectangle on the basis of the character region and the frequency of histograms, and a character rectangle determining part 165 specifies a region where the temporary line candidate rectangle overlaps as a character region. A character recognition processing part 166 performs character recognition of the character region specified by the character rectangle specifying part 165. COPYRIGHT: (C)2011,JPO&INPIT
