METHOD AND APPARATUS FOR CURRENCY DISCRIMINATION

摘要

An improved method of and device for generating a master pattern correspondi ng to a given denomination for use in a discrimination system capable of discriminating among currency bills of different denominations. The method comprises the steps of generating a plurality of component patterns for a given denomination by scanning at least one genuine bill of the given denomination and generating a master pattern for t he given denomination. The master pattern is derived from an average of the component patterns. The component patterns represent analog variations in characterist ic information detected from a genuine bill during scanning. The master pattern represents an average of analog variations of the characteristic information for the given denomination.
