Research On The Digital Watermark

The paper researched the watermark's creation and embedding algorithms and brought forward my own solution and means. This paper was made up of five chapters: the first chapter introduced the watermark's basic situation and knowledge; the second chapter introduced an embedding algorithms based on the combining of SVD and DWT and adopted a new means of using HVS .To improve the vision characters and enhance the solidity, the disputed square error means was displayed by the edge detection with the massage of veins to ascertain the watermark's embeding area. The calculation and effect had been enhanced greatly, then the selection of embedding intensity was expounded with substantial theory; the third chapter advanced two innovation applyings in embed watermark's creation; the fourth chapter researched the p-value m-sequence's pseudorandom property and gave its proving course .Its pseudorandom property can be used in the encrypting of multivalue watermark; the forth chapter was the summarization and prospect to the future.
