摘要
研究了一种基于小波变换的音频数字水印算法,水印为一幅二值图像。仿真实验表明该算法具有较强的稳健性,可用于数字音频产品的版权保护。
In this paper,a audio digital watermarking algorithm which is based on the dis-crete wavelet transform(DWT )is discussed.A seal image is used as a watermark here.Emula-tional experiment results show that the method is robust to some signal manipulations.It can be used for copyright protection.
