一种基于Fibonacci 系的数字水印新方法
A Novel Digital Watermarking Approach Based on Fibonacci Sequence
摘要
Abstract
Based on Fibonacci sequence, the article discusses a method of digital watermarking about anti-JPEG compression.The algorithm constructs the Fibonacci quantification table Q of quantified DCT coefficients and the coefficient modification table M of embedded in the watermark by means of the Fibonacci sequence,Fibonacci integer sequences, as well as the rabbit sequence S. It can be used to solve the conflict between image compression quality and the robustness of watermarking by changing the threshold value N of constructed M table. As the Fibonacci number increases progressively in the form of the golden section and the main principle of the JPEG compression is DCT transform, this algorithm has a very good robustness for anti-JPEG compression through constructed quantification table and the coefficient modified table to modify the DCT of DC component embed the watermark. The experimental results showed that when the threshold value of structured M table N = 7,the image compression quality IQ = 40%, and the correct rate of the watermark extraction using the algorithm can reach more than 90%.关键词
