| 摘 要： | 通过对运动物体图像运动模糊的研究,分析了图像运动模糊的降质过程.针对运动参数未知的情况,提出一种新的运动模糊复原方法,该方法首先运用小波的多分辨分析特性进行图像的消噪处理,然后通过Hough变换与频域处理相结合估算点扩散函数(PSF)的方向,利用自相关的方法估算PSF的尺度,最后通过维纳滤波还原图像.实验证明,该方法在一定范围内,能够有效地消除运动模糊造成的图像质量下降.

| Abstract: | The degrading procedure of motion blur is analyzed with research of it.A new recovering method is proposed for the unknown motion parameter.The multi-resolution of wavelet is used for the image preprocessing.After that,Hough transform is made for the direction of the PSF and correlation is calculated for the length of the PSF.At the end,the blurred image is recovered by Wiener filter.It is proved that the degrading for the motion blur can be reduced effectively by this method. |
