| 摘 要： | 数字图像复原旨在由降质图像重建清晰图像,运动模糊是最常见的降质模式,模糊参数的正确估计是去模糊的前提.文章提出了新的运动模糊角度估计方法,该方法基于Gabor滤波的角度估计,运动模糊尺度采用自相关函数算法求解,进而采用Wiener滤波进行图像复原.对一系列模糊图像进行测试,结果表明,该方法比现有的方法具有视觉上的优越性.

| Abstract: | Digital image restoration aims at constructing the original image from the degraded image.The motion blur is very common in various degradation patterns.The estimation of motion blur parameters can influence the result of deblur.In this paper,a new method to estimate the blur angle is proposed based on Gabor filter.The autocorrelation function is adopted to estimate the blur length,then the Wiener filter is used for the restoration.A series of images are taken for experiments,and the results show that the algorithm is superior to the existing methods visually. |
