Abstract: The disclosure discloses a paper money identification method and device. The paper money identification method comprises: obtaining entire grayscale image data of the paper money to be tested; dividing the entire grayscale image of the paper money to be tested into a plurality of areas; comparing the feature value of each area with feature value of a corresponding area in a paper money template to judge whether the two compared areas are matched; counting the number of unmatched areas of the paper money to be tested; judging whether the number of the unmatched areas is greater than a second preset threshold; and determining that the paper money to be tested is the altered money when the number of the unmatched areas is judged to be greater than the second preset threshold. By the disclosure, the accuracy of identifying the altered money is improved.

Abstract: The disclosure discloses a method and device for controlling a composite scanning device, and a composite scanning system. The composite scanning system includes: a composite scanning device and a host which includes: an application module configured for performing a first capability setting on the composite scanning device, obtaining the scanned image data from the composite scanning device after the first capability setting, and processing the scanned image data in a first TWAIN session state; and a configuration module configured for performing a second capability setting on the composite scanning device according to the processing result of the application module in the first TWAIN session state. By the disclosure, the efficiency of capability setting in the composite scanning system which is compatible with TWAIN protocol can be improved.
