Abstract
An improved method of generating a master pattern corresponding 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 the given denomination. The master pattern is derived from an average of the component patterns. The component patterns represent analog variations in characteristic 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.
