摘要
在图像拍摄记录的过程中，图像捕获系统因各种原因常常不能精确成像，故而极易产生模糊图像，离焦模糊是常见的模糊图像之一。本文重点介绍了一种倒谱分析方法，在倒谱域对离焦模糊图像的模糊参数进行分析。利用MATLAB软件编制倒谱分析程序进行实验，结果表明倒谱分析方法能更准确地评估模糊参数，将对图像检验起着指导作用。
When taking a photo, the image capture system usually fails to record the images precisely for various reasons, thus the photos are easy to be blurry.Defocused image is one of the common blurry images.This paper introduces a kind of cepstrum analysis method, which is used to analyze various blurry models of blurs.The cepstrum analyzing experiment using MATLAB shows that cepstrum analysis can estimate blurred parameters more cotrecdy.lt is clear that the cepsu＇um analysis will provide a guidance in the work of all image exanaination.
