在小波域中实现的奇异谱分析音频隐藏算法.

This paper proposed a new speech concealment algorithm for many speech concealment algorithms with small hidden capacity and bad transparency. Firstly, it compressed and encoded the concealed information by G. 729A, and then applied the lifting wavelet transform and singular spectrum analysis to the audio information hiding. Experiments show that the audio file embedded in the hidden information by the algorithm not only has a significant improvement in the hidden information capacity, but also has good transparency, and can also resist certain attacks. The algorithm in concealed capacity, transparency and robustness reaches a better balance. [ABSTRACT FROM AUTHOR]
