Abstract
A method of identifying the denominations of pieces of paper, for example, bills or securities. The method defines a separating hyperplane for each of all combinations of two denominations taken from the N denominations which divides the space so that the distribution ranges of the image data of the two denominations are completely separated into the different regions and storing the data defining the separating hyperplanes as template data in a memory; selects two denominations from the N denominations and retrieves the template data corresponding to the combination of denominations from the memory when the image data of a piece of paper of an unknown denomination is read in with a sensor for reading patterns; determines which one of the regions divided by the separating hyperplane the image data of the piece of paper is in; discards the denomination in the region in which the image data of the piece of paper is not present; repeats the same procedures by selecting two denominations from the remaining candidate denominations to reduce the number of the candidate denominations until only one denomination is left; and determines that the denomination remaining as the last is the denomination of the piece of paper.
