Abstract

The embodiments of the present invention relate to the field of banknote identification, and in particular to a banknote defacement identification method, device, storage medium and financial equipment. The banknote defacement identification method includes the following steps: Step S1: divide the image of the banknote to be tested into grids, and determine the brightness of each grid; Step S2: calculate the difference between the brightness of each grid of the banknote to be tested and a preset first average brightness value, to obtain the brightness fluctuation value of each grid; step S3: compare the brightness fluctuation value with the preset brightness fluctuation threshold; step S4: if the brightness fluctuation value is greater than the preset brightness fluctuation threshold, determine that the banknote to be tested is a defaced banknote . The banknote defacement identification method, device, storage medium and financial equipment have the advantage of unlimited identification of defacement in the banknote area.

Description

technical field [0001] The invention relates to the field of banknote identification, in particular to a banknote defacement identification method, device, storage medium and financial equipment. Background technique [0002] In areas with few banknote patterns or relatively simple patterns, it is easy to be artificially written or stained, and the handwriting or oil stains will be more conspicuous. When banknotes are defaced, it is easy to fail the banknote verification. The existing method or device for identifying defacement of banknotes can only detect and identify defacement in a specific area. When the fouling is not within a specific area, the fouling cannot be detected. [0003] Therefore, how to provide a method or device capable of identifying whether all positions of banknotes are stained has become a demand in the prior art. Contents of the invention [0004] The invention provides a banknote defacement identification method, device, storage medium and finan...
