Abstract (en)
In a paper sheet recognition apparatus, a block setting unit (12a) divides a captured image of a paper sheet into pixel blocks of a predetermined number of pixels, a pixel statistics unit (12b) calculates statistics of a block value for each pixel block of a plurality of paper sheets, a valid area learning unit (12c) learns the pixel blocks valid for fitness determination as a valid area, a threshold value learning unit (12d) learns threshold values of the valid area, and a fitness determining unit (12e) performs fitness determination of the paper sheet based on threshold value information output by the threshold value learning unit (12d).
