  • Method and system for identifying characters on a valuable medium
    Patent number: 9977957
    Abstract: A character recognition method for recognizing a character printed over a background pattern on a valuable medium includes acquiring a character image captured by capturing the character printed on the valuable medium; evaluating a degree of similarity between the character image and each template image, the template image having been obtained beforehand by capturing each character that had a possibility of having been printed on the valuable medium and of which background area is evenly filled; and determining that the character corresponding to the template image showing the highest degree of similarity at the evaluating is the character included in the character image.
    Type: Grant

  • Character string extraction method and character string extraction device
    Patent number: 9008431
    Abstract: In a character string extraction method, a character portion, a rim portion, a character frame, and a character string frame are set, a feature value of each image in the character portion and the rim portion is calculated for each character frame, a character string frame evaluation value is calculated based on the feature value for the character string frame, a position of the character string frame is moved on the paper sheet image, and the image in the character portion is extracted by using the character string frame at a position at which the character string frame evaluation value reaches a maximum.
