| 摘 要： | 主要提出了基于混沌细胞自动机的小波域数字音频水印算法.首先由Logistic混沌序列模型产生序列,其次产生的序列通过细胞自动机产生要嵌入的数字水印.同时将原始音频信号通过小波表变换,提取出其低频系数,并将水印信号嵌入其中.实验证明:由混沌细胞自动机产生的数字水印具有很好的掩蔽性和鲁棒性,在各种攻击下(包括白噪声、低通滤波、重量化、有色噪声等)仍然能够很好的检测出来.

| Abstract: | WT5"BZ]This paper introduces digital audio watermarking algorithm based on chaos and cellular automata using DWT.At first chaos sequences are engendered by Logistic chaos model, and then was input into cellular automata which engenders digital watermarking. At the same time original audio signal is transformed into DWT field, and extracting low frequency coefficients into which watermark are embedded. Experiments results illustrate that the watermark, which is engendered by chaos and cellular automata, has good imperceptions and robustness. In addition, the mark can be detected perfectly against some signal processings, including white noise, low-pass filtering, re-quantzation and colored noise etc. WT5"HZ] |
