Embodiment 1
[0037] Figure 1a It is a flow chart of a bill detection method provided by Embodiment 1 of the present invention. This embodiment is applicable to the detection of abnormal bills. The method can be executed by a bill detection device, which can be implemented by software and / or hardware It can be realized in a way, and generally can be integrated in computer equipment (such as various financial equipment, equipment, terminals, etc.). Correspondingly, such as Figure 1a As shown, the method includes the following operations:
[0038] S110. Obtain a fluorescence image of the bill to be tested.
[0039] Among them, the bill to be tested can be a bill that needs to detect abnormalities, and the bill can include but not limited to securities, deposit certificates, bills of lading, waybills, invoices, movie tickets, shopping receipts, train tickets or tickets, etc. Any bill with a fluorescent mark can be As the bill to be tested, the embodiment of the present invention does not li...
Embodiment 2
[0057] Figure 2a It is a flow chart of a bill detection method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. The fluorescent area image is binarized to obtain a binarized fluorescent image and a specific implementation manner of detecting the abnormality of the bill to be tested according to the expanded fluorescent image. Correspondingly, such as Figure 2a As shown, the method of this embodiment may include:
[0058] S210. Acquire a fluorescent image of the bill to be tested, and intercept a fluorescent area image according to the fluorescent image.
[0059] In an optional embodiment of the present invention, the intercepting the fluorescence region image according to the fluorescence image may include: intercepting a rectangular region in the fluorescence image where the fluorescence marker is located to obtain the fluorescence region image.
[0060] In the embodiment of the present invent...
