The data synthesis module 13 is configured to embed the anti-counterfeit information processed by the image processing module 12 into an electronic document to generate a printed document. The color of the anti-counterfeiting information in the paper file printed by the printed document is adapted according to the content of the electronic document, so that the anti-counterfeiting information in the paper file is not easy to perceive, the display effect of the file is not damaged, and the visual comfort and the attractiveness of the paper file are improved.
As a preferred embodiment, the HVS-based intelligent print document processing system 100 further comprises: an electronic document storage module 14, an anti-counterfeiting information storage module 15 and a printed document storage module 16. The electronic document storage module 14 is used to store electronic documents. The anti-counterfeiting information storage module 15 is used for storing anti-counterfeiting information. The print document storage module 16 is used to store a print document.
As a preferred embodiment, the HVS-based intelligent print document processing system 100 further comprises: an image acquisition module 17. The image obtaining module 17 is configured to obtain image information of a paper document to be processed. The pre-processing module 10 pre-processes the acquired image information, and the image processing module 12 extracts anti-counterfeiting information from the pre-processed image information.

Meanwhile, the electronic document and the anti-counterfeiting information are used as processing objects, and dynamic color values which are in accordance with HVS characteristics of the electronic document are comprehensively calculated.
As a preferred embodiment, the specific method for embedding the processed anti-counterfeiting information into the electronic document by the data synthesis module 13 is as follows: the data synthesis module 13 sets the number of the anti-counterfeit information and the embedding position according to the content of the electronic document and the anti-counterfeit information. By the operation mode, when the printed document is printed into a paper file, the anti-counterfeiting information is displayed on the paper file in a proper quantity and proper position, and the content of the read document is not influenced.
As a specific embodiment, the image information of the paper document to be processed is acquired by the image acquisition module 17. The image information is preprocessed by a preprocessing module 10. The anti-counterfeiting information is extracted from the preprocessed image information through the image processing module 12.
Further, the anti-counterfeiting information extracted by the image processing module 12 is enhanced by the image enhancement module 18, so that the dynamic color value of the anti-counterfeiting information is increased to the original state, and the image-text display of the anti-counterfeiting information is clearer. The enhanced anti-counterfeiting information is output through the image output module 19 to be used for verifying the paper document, so that the anti-counterfeiting tracing of the paper document is realized.
