Research On Limited Motion-Blurred Image Processing

We often meet this difficult type in the process of image acquiring.Such as the subject move a little distance when we shoot it.Then the image we acquired will be blurred.It is so-called motion-blurred images.How to restore the blurred image plays an important part in the image restoration and digital image processing.The main task of the motion-blurred image restoration is to alleviate the degradation of image quality,so that the image can be rich in detail.This thesis discusses the degradation model of motion-blurred image based on the imaging principle.And then it summarizes the basic ideas to deal with this problem through the motion-blurred image's formation.The thesis focuses on the classic motion-blurred image restoration method,the corresponding algorithm and motion-blurred image restoration applications.Firstly,the thesis analyzes the relevant factors of the motion-blurred image including the image noise,frequency image processing techniques,Fourier transform and Radon transform.The gray-scale image projection is another part of the thesis. Secondly the thesis analyzes the restoration processing from three aspects including estimating the correct motion-blurred parameters,selecting the appropriate image restoration algorithm and assessing the quality of image restoration.The thesis estimates the degradation parameters and then restores the motion-blurred image with the help of these parameters.Finally it evaluates the quality of restoration image according to the image blurring factors and the results of image restoration.The restoration of motion-blurred image is very difficult.This thesis only discusses the uniform motion-blurred image.There are still a lot of problems in this domain and the research will go on and on.
