摘 要 图像在获取、传输和存储过程中会受到如模糊、失真、噪声等原因的影响，这些原因会使图像的质量下降。因此，我们需要采取一定的方法尽可能地减少或消除图像质量的下降，恢复图像的本来面目，这称为图像复原。通过阅读图像复原技术相关资料，本文主要探讨了维纳(Wiener)滤波、约束最小二乘滤波算法、Lucy-Richardson算法和盲解卷积算法，并使用相关的工具箱函数deconvwnr函数、deconvreg函数、deconvlucy函数、deconvblind函数进行仿真。另外本文对上述算法进行了仿真实现，并分析了四种算法的实验结果。

Based on the MATLAB of defocus blurred image restoration
Abstract Image in the acquisition, transmission and storage process will be subject to such as blurring, distortion, noise and other reasons, these reasons will make the image quality degradation.Therefore, we needed to take a certain amount of ways to reduce or eliminate image quality to fall, to restore the image of self, this is known as image restoration. By reading the image restoration technology related data. 千只眼This paper mainly discusses the Wiener filter, constrained least squares filtering algorithm, Lucy-Richardson algorithm and blind deconvolution algorithm，and the deconvwnr function，the deconvreg function ，the deconvlucy function and the deconvblind function are used for emulation.
This article on the above algorithm to simulation and experimental result analysis of four kinds of algorithms.
