The Quantificational Relation of Imperceptibility,Robustness and Hiding Rate in Digital Watermarking

摘要：

Imperceptibility, robustness and hiding rate are the three most important indexes of digital watermarking. They restrict each other. In this paper, we firstly give a digital watermarking model and the definitions of the three indexes. Based on them, the quantificational relation of the three indexes is gained. Then we point out that the embedding intensity is the key to reach their tradeoffs and propose the method to calculate the embedding intensity. Finally the experimental results show two points: 1) The relation of the three indexes and the method to calculate the embedding intensity have important action in designing watermarking algorithms; 2) The relation and the method is correct.
