摘要： 提出了一种基于整型提升小波变换与人类听觉系统(HAS)的自适应数字音频水印嵌入算法。该算法具有4个特点。实验结果表明,该自适应数字音频水印嵌入算法不仅具有较好的透明性,而且对诸如叠加噪声、有损压缩、低通滤波、重新采样、重新量化等攻击均具有较好的鲁棒性。

Abstract: A new adaptive digital audio watermarking based on integer lifting wavelet transform and human auditory system is presented. There are four features in the proposed algorithm. Experimental results show that the proposed watermarking scheme is inaudible and robust against various signal processing such as noising adding, lossy compression, low pass filtering, re-sampling, and re-quantifying.
