Examples
- In the first step the wavelet coefficients were quantized by using a psycho - acoustic model
在步骤1中，通过心理音响学模型对小波系数进行量化。 - At last , the encoding hardware structure of mpeg - 1 layer ii is put forward . second , in the paper , we have analyzed every module of the structure and estimated it ' s complexity . then the sub - band filter bank and psycho - acoustic modules are more investigated
其次，分析了硬件结构中各个模块并估计了它们的运算复杂性，然后对子带滤波器组和心理声学模型作了进一步的探讨，提出了基于fft的高效实现算法及其硬件结构。 - Theoretical expatiate on general concepts and fundamental principles of information hiding and steganography , also point out possible directions for further research , also analysis the probability of speech as the host carry signal and efficient masking characteristics of psycho - acoustic model , it is shown that : there is an improvement on imperceptibility according to human auditory masking effect
阐述了信息隐藏技术和隐写技术的重要概念、基本理论以及广阔的应用前景。分析了将语音信号作为宿主载体信号的可行性,参考心理声学模型的特性,得出结论:基于人耳听觉掩蔽效应的隐写算法,在隐蔽性上有很大的提高。
