Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings.

[0022] Such as figure 1 As shown, it is the process flow of the bill anti-counterfeiting identification method based on the global characteristics of the bill, including the following steps:

[0023] Step 10 collects the images of the checked bills under different spectral irradiations, and performs preprocessing operations on the collected bill images, so that the bill image parameters conform to the standard bill image template;

[0024] Step 20 converts the checked bill image to the HSI color space, and obtains the bill hue H, saturation S and brightness I component feature images;

[0025] Step 30 correlates the component pixel matrix of the tone H, saturation S and brightness I components of the bill global feature image with the standard i...

Abstract

The invention discloses a bill anti-counterfeiting identification method based on bill global characteristics. The method comprises steps that images of a bill under different spectrum irradiation conditions are acquired, the acquired bill images are pre-processed, and bill image parameters are made to be consistent with standard bill image templates; the bill images are transferred to an HSI color space, and bill tone, saturation and brightness component characteristic images are acquired; a tone, saturation and brightness component matrix of a bill global characteristic image and a standard image are detected to acquire tone, saturation and brightness correlation coefficients; a total correlation coefficient of global characteristics of the detected bill image and the standard bill image is calculated, the bill characteristic matching result is determined according to the correlation coefficient, and authenticity of the bill is determined on the basis. The method is advantaged in that intelligent global bill characteristic extraction can be realized, correlation evaluation of the HIS images of the global characteristics of a detected bill and a standard bill is automatically carried out, comparison with a preset threshold is carried out, authenticity of the bill is determined, and intelligent bill anti-counterfeiting identification is realized.

Description

technical field [0001] The invention relates to the technical field of bill anti-counterfeiting identification, in particular to a bill anti-counterfeiting identification method based on the global characteristics of bills. Background technique [0002] The bill is made according to a certain form, and it is a certificate stating the obligation to pay a certain amount of currency, and it is a certificate for cashier or delivery of goods. With the rapid development of national economy and science and technology, bills are widely used in daily life, and the diversity and complexity of bill layouts also increase accordingly. Lawbreakers seek huge profits by making fake bills. Falsified bills and technologies emerge in endlessly. While endangering the order of the social market economy, it also brings great difficulties to financial management. The prevalence of counterfeit and counterfeit bills has caused serious economic losses to the country. [0003] In order to ensure the...
