A document watermark detection and recognition system comprises a document uploading module, a document format conversion module, a document watermark extraction module, a document watermark encodingmodule, a document watermark comparison module and a result display module, the document uploading module is used for uploading a document to be detected, and the document format comprises a word format and a pdf format; the document format conversion module is used for converting the uploaded document into an image format so as to facilitate subsequent detection; the document watermark extractionmodule is used for extracting and storing a watermark image in a document image; the document watermark encoding module is used for encoding a watermark image into text information for subsequent comparison; the document watermark comparison module is used for comparing the watermark image text with a watermark image text in a database; and the result display module is used for displaying whetherthe document is repeated with the document in the database or not.
Description
technical field [0001] The invention relates to the technical field of image retrieval, in particular to a document watermark detection and recognition system. Background technique [0002] At present, the University of Illinois, a well-known foreign university that has done a good job in image retrieval technology in the field of scientific research, proposed the Multimedia Analysis and Retrieval System (MARS for short) to provide direction for the development of image retrieval. In China, there are color image-based navigation and retrieval systems from Tsinghua University, color-based Photo Navigator and shape-based Photo Engine retrieval systems from the Computer Department of Zhejiang University, etc. These researches have guiding significance for the development of image retrieval technology. In the commercial field, there are commercial companies such as Google, Tineye, and Picitup that research image retrieval technology abroad, and domestic famous companies such as ...
