[Special Effects] Wiener-filtering

Description: 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 noise and median filtering method chosen recovery subsequent model-based motion blur degradation modeling, Wiener filtering respectively, using several methods to restore the source image . doc document derived in the course of the Wiener filter, and use a variety of matlab realize the Wiener filter, the code attached to the article.
