摘 要 运动模糊恢复就是利用运动模糊退化的某种先验知识来重建或恢复原有图像 在运动模糊的点扩散函数未知的情况下

估计运动模糊的点扩散函数是运动模糊恢复的前提和关键 从傅立叶变换的角度对匀速直线运动模糊图像的点扩散函数在频域

。

论证了点扩散函数在频域内的零点特性及模糊图像两次傅立叶同态变换后的方向特性 并提出了利用这中的特点做了理论分析,些特性进行运动模糊方向估计的方法及两种模糊距离的估计方法 实验结果证明了所提出方法的有效性-Abstract motion blur is to use motion blur to restore the degradation of some prior knowledge to rebuild or restore the original image in the motion blur point spread function of the unknown circumstances:. , It is estimated that the motion blur point spread function is a prerequisite for the restoration of motion-blurred and critical perspective from the Fourier transform of the uniform linear motion blurred image of the point spread function in the frequency domain. Demonstrated that the point spread function of the zero in the frequency domain characteristics and the two blurred images after Fourier transform with the direction of state properties and proposed use of the characteristics of this has done a theoretical analysis, some characteristics of the estimated direction of motion-blurred and the two kinds of fuzzy distance estimation results proved the effectiveness of the proposed method
