摘要 提出了一种利用Kalman滤波对模糊图像进行恢复的方法。当降质函数已知时 ,首先对模糊图像在一个方向进行傅立叶变换 ,然后在另一方向进行快速的Kalman滤波 ,将两维的恢复问题转化为若干个一维问题。为克服边缘效应 ,构造了原图像的镜像 ,并给出了滤波结果。 On image restoration using Kalman filter is pnesented.Here the blur function is known.By applying fast Fourier transformation in a given direction (vertical or horizontal)and then Kalman fitering in the other direction ,the 2 D restoration problem is transformed in to a set of N 1 D restoration problems.To overcome the boundary problems,a mirror image is used.
