Psychoacoustics of the human hearing is explicitly included into the algorithm through modifying the MP metric by the time-varying maskingthreshold of the input signal.
通过计算时变输入信号的心理声学参数,用信号的掩蔽值对匹配跟踪矩阵进行加权。

Watermarking embedding algorithm based on auditory masking is proposed in this paper, which embeds watermarking based on maskingthreshold in low-band coefficients of DCT transformation.
