| 摘 要： | 该文提出了一种新的音频水印算法。它充分利用了离散小波变换的多分辨率特性,在小波变换的细节部分搜索局部极值点,通过修改局部极值及其相邻点的幅度值,实现水印信息的嵌入。水印检测不需要参考原始音频。实验结果证明了该算法的鲁棒性和不可感知性。

| Abstract: | This paper presents a new audio watermarking algorithm.This algorithm makes use of good characteristic of multi-resolution.The watermark is embedded by using the method of searching local extremums in the low-frequency coefficients of DWT domain of an audio signal and modifying the local extremums and its neighboring coefficients.The watermark can be extracted without the original audio signal.Experimental results demonstrate the audio watermarking algorithm is robust and imperceptible. |
