Device, method and program for paper discrimination

摘要

The image manipulation unit ( 17 ) corrects the tilt and color shade of the paper-piece image data obtained by the optical sensor unit ( 13 ). The template comparison unit ( 18 ) makes the for-comparison banknote image data of each denomination from the paper-piece image data made by the image manipulation unit ( 17 ) and the reference data of each denomination stored in the reference data unit ( 19 ). And the process of pattern matching of the for-comparison banknote image data with the template with the corresponding denomination stored in the template unit ( 20 ) is performed for all denominations, and the denomination with the closest distance between patterns is discriminated as the denomination of the piece of paper. The result of the discrimination is stored in the memory unit ( 21 ).
