| 摘 要： | 提出了一种基于离散余弦变换及奇异值分解的音频水印算法。首先对二值水印图像进行奇异值分解求出奇异值,然后对所得奇异值进行基于音频信号变换域性质的调制,并对音频信号进行离散余弦变换并计算水印嵌入点,最后将经过调制的水印信号嵌入。仿真试验证明这种自适应音频数字水印算法具有稳健性和不可觉察性。

| Abstract: | In this paper,present an audio digital watermarking method based on DCT(Discrete Cosine Transfer) and SVD(Singular Value Decomposition). First, the singular value decomposition of the binary watermarking image is computed to obtain the decomposed values. Second, modulated the values based on the audio signal's transform domain character. The audio signal was performed by DCT. The points that will embedded watermark signal were computed based on it. Finally the modulated watermark was embedded into the points. Experimental results demonstrate that the adaptive method is robust and imperceptible. |
