MATLAB建模数字下变频的滤波器组设计，和幅频特性分析（cic级联补偿滤波器，和cic级联补偿滤波器和半带滤波器）-Digital down conversion filter bank design, analysis and amplitude-frequency characteristics of the the cic cascade compensation filter and the cic cascade compensation filter and half-band f

本文主要基于退化-恢复模型进行研究，首先对Lena图像加入了Gauss 噪声，并选用中值滤波方法恢复；随后基于运动模糊模型进行退化建模，分别采用几种维纳滤波方法对源图像进行还原。 doc文档中推导了维纳滤波过程，并用matlab实现了了多种维纳滤波器，代码都附在文中。-This article is mainly based on the degradation- the recovery model to study, first joined the Gauss Lena image n
