倒谱域数字音频水印嵌入和提取,matlab基于倒谱域的数字变换-Cepstrum domain digital audio watermark embedding and extraction

针对散焦模糊图像，用matlab实现了先基于倒谱相关性对PSF的参数估计，再用维纳滤波实现复原的算法。-Defocus blurred image using matlab first estimated based on the parameters of the cepstrum on PSF, and then the Wiener filter recovery algorithm.

Including the generalized cross-correlation function GCC time delay estimation, University of numerical analysis algorithms, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc.
