Embodiment 1

[0031] Figure 1a It is a schematic flow chart of a banknote authenticity identification method provided in Embodiment 1 of the present invention. This method is applicable to the situation of banknote authenticity identification and can be executed by a banknote authenticity identification device, wherein the device can be realized by software and / or hardware. Generally, it can be integrated in the equipment with banknote verification function. Such as Figure 1a As shown, the method may include:

[0032] Step 101 , cut out the characteristic area containing the denomination number from the banknote grayscale image obtained by infrared light scanning.

[0033] Exemplarily, the banknote authenticity identification method provided in this embodiment is suitable for banknotes, especially for Thai baht, and the grayscale image of banknotes obtained by infrared scanning may be an infrared reflection image, Figure 1b The schematic diagram of the infrared reflection image of the T...

Embodiment 2

[0042] figure 2 It is a schematic flowchart of a banknote authenticity identification method provided by Embodiment 2 of the present invention. On the basis of Embodiment 1 above, this embodiment optimizes "determining the boundary information of denomination numbers contained in the characteristic area", Such as figure 2 As shown, the method may include:

[0043] Step 201 , cut out the characteristic area containing the denomination number in the grayscale image of the banknote obtained by scanning the infrared light.

[0044] Step 202: Determine the boundary information of the denomination numbers included in the feature area according to the wavelet transform modulus maximum algorithm and the second preset threshold.

[0045] Exemplarily, the grayscale matrix refers to a matrix that stores the grayscale value of each pixel in the image. For example Figure 1bAs shown in the image, a grayscale matrix corresponding to the pixels in the feature area is constructed. In th...

Embodiment 3

[0074] Figure 3a It is a schematic flow chart of a banknote authenticity identification method provided by Embodiment 3 of the present invention. On the basis of the above-mentioned embodiments, the method optimizes "according to the boundary information to obtain the projection information of the characteristic region". Such as Figure 3a As shown, the method may include:

[0075] Step 301 , cut out the characteristic area containing the denomination number in the grayscale image of the banknote obtained by scanning the infrared light.

[0076] Step 302. Determine the boundary information of the denomination numbers contained in the feature area.

[0077] Step 303. Adjust the gray value of the pixels contained in the feature area according to the boundary information to obtain a boundary image.

[0078] Exemplarily, according to the boundary information, determine all the pixels contained in the above-identified boundary, adjust the gray value of all the pixels contained ...

Abstract

The embodiment of the invention provides a banknote authenticity identification method and device. The method comprises the steps that the characteristic area including the denomination number is cutfrom the banknote grayscale image obtained through infrared scanning; the boundary information of the included denomination number in the characteristic area is determined; the projection informationof the characteristic area is obtained according to the boundary information; and the banknote authenticity is determined according to the projection information. With application of the technical scheme, characteristic extraction of the characteristic area can be accurately performed through the determined boundary information and then the banknote authenticity can be determined according to theprojection information of the boundary information so that the accuracy of banknote authenticity identification can be greatly enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information processing, and in particular to a method and device for authenticating banknotes. Background technique [0002] With the development of the economy, the circulation of banknotes is increasing, and intelligent unmanned toll collection systems based on banknote recognition technology have appeared in many industries. For example, banknote recognition technology can be applied not only to automatic vending and ticket sales, but also to systems such as bank ATMs or automatic payment machines in business halls. At the same time, the invention of the banknote counter also provides convenience for various industries. The application of banknote recognition devices saves a lot of human resources and greatly improves work efficiency. [0003] Counterfeit currency includes counterfeit currency, which refers to counterfeit currency made by various methods that imitate the patt...
