摘要

模糊图像盲恢复的关键是点扩散函数的估计和非盲反卷积算法。针对相机抖动引起的图像模糊低信噪比、模糊长度小的问题，提出了一种快速鲁棒的模糊核函数参数估计算法。然后利用快速非盲反卷积方法对模糊图像进行复原。实验结果表明，对于相对线性运动模糊的运动，该算法具有更快的恢复速度和良好的恢复效果。

Motion blurred image blind restoration base on parameter estimation of PSF

The key of the blurred image blind restoration is the estimation of the point spread function and non-blind deconvolution algorithm.For the problem of the image blur which low SNR and small blur length caused by the camera shake,a fast robust algorithm is proposed to estimation the parameters of blur kernel function.Then the blurred images are restored by using a fast non-blind deconvolution method.Compared with R.Fergus' algorithm,the experiment results prove that the algorithm for motion blurred by the relative linear movement has faster speed and good recovery effect.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
