Bill anti-counterfeiting identification method based on bill watermark distribution characteristics

Abstract

The invention discloses a bill anti-counterfeiting identification method based on bill watermark distribution characteristics. The bill anti-counterfeiting identification method comprises the following steps of: selecting an initial watermark type, and constructing elements in a combined template according to the initial watermark type so as to construct the combined template; processing bill images acquired by a camera to acquire standardized bill images; realizing binarization of the bill images by utilizing a local threshold method; searching a target object same as or similar to the combined template in the bill images and performing the matching of the combined template by taking a correlation coefficient as a measurement standard; extracting watermark distribution characteristics of the bill images; performing characteristic matching based on the watermark distribution characteristics and identifying true and false of bills. According to the bill anti-counterfeiting identification method based on the bill watermark distribution characteristics, disclosed by the invention, combined detection of each watermark target is realized, and true and false of financial bills can be effectively identified.
