摘要: 该文提出了一种新的盲音频水印算法。它充分利用离散小波变换的多分辨率特性和离散余弦变换的能量压缩能力,通过量化处理把降维后的二值图像水印嵌入到原始的音频信号中,在水印的提取过程中不需要原始音频信号的参与。仿真实验证明了算法的鲁棒性和不可感知性。Abstract: This paper presents a novel blind audio digital watermark algorithm. It makes full use of the multi-resolution of DWT and the energy compression of DCT and embeds binary image watermark in the audio by quantification process. The watermark can be extracted without the original audio signal. Experimental results demonstrate the algorithm is robust and imperceptible.
