Abstract
A method and system for determining the extent of deterioration of a bill includes generating transmitted and reflected light images. The reflected and transmitted light intensities of the transmission and reflection light intensity images are used to determine one or more disorder curve lengths for each image of the bill. Each disorder curve length is compared with a corresponding predetermined disorder curve length for a corresponding image of a reference bill to generate an evaluation factor. The positions of the evaluation factors on an evaluation map indicate the extent of deterioration of the bill.
