摘要
提出了一种基于小波变换的自适应音频水印算法,把一幅二值图像作为水印信息自适应地嵌入音频信号中。仿真实验表明嵌入的水印具有良好的鲁棒性和透明性。
This paper presents an adaptive audio watermark algorithm based on wavelet transform,which embeds a sheet of binary image into the audio signal adaptively as the watermark.Simulation experiment shows that the embedded watermark has good robustness and transparency.
