摘要： 提出了一种运动模糊图像恢复模型，运动模糊图像经傅立叶变换后在频域有频谱零点进行参数估计，通过霍夫变换初步求得运动模糊图像的点扩展函数，当估计出运动模糊图像的点扩展函数的参数后，用神经网络方法进行恢复。这种恢复模型可以对任意角度的匀速运动模糊图像的恢复取得恢复效果。该方法具有操作简单和全局搜索收敛的优点, 实验证明这是一种比较好的运动模糊图像恢复方法。

Abstract: This paper presents a method of motion blurred image restoration based on frequency spectrum and the Hopfield network. The parameter of PSF of the motion blurred image can be estimated from frequency spectrum according to spectral property of the motion blurred image. This method is characterized by convergence and simplicity. The experiment result shows that this method can effectively restore the motion blurred image.
