Method and device for examining money

Abstract

The invention relates to a method and a device for examining money. The method for examining money comprises the following steps: training a single-class support vector model: according to a collected money image vector, carrying out algorithm training to obtain a single-class support vector and a vector model; scanning money images: scanning the images for preliminarily-examined money; extracting an image characteristic vector: processing a money image pixel characteristic into a standard matrix conforming to the input of the support vector machine, and extracting the money image characteristic vector; and identifying by a single-class classifier: calculating the extracted money image characteristic vector by the single-class support vector model, and judging the fact or fiction of the money according to a calculation result. According to the method and the device for examining money, the money is examined and identified by the single-class support vector model. Money examining technology with high precision and high reliability can be realized by the method and the device for examining money.

Description

technical field [0001] The invention relates to a banknote checking method and a banknote checking device, in particular to a banknote checking method and a banknote checking device which use a single-class support vector model to verify the authenticity of currency. Background technique [0002] The verification of the authenticity of currency has become one of the important functions in the existing deposit and withdrawal equipment, and there are many known methods for the verification of currency at present. For example, one or more sensors are used to collect the anti-counterfeiting features of currency, such as magnetism, fluorescent reaction, color-changing ink, etc., and the purpose of counterfeiting is achieved by detecting the presence or absence or distribution threshold of the anti-counterfeiting features. Another example is the method described in the patent No. CN 200420084129.7. This type of method assumes that the classification boundaries of genuine coins and...
