摘要
对模糊的成像结果进行图像复原,采用高斯函数作为点扩展函数,应用于三维逆滤波和维纳滤波算法中,改进了这两种算法。实验结果证明,改进后的维纳滤波算法复原三维序列的结果比改进后逆滤波算法得到的结果更好。此外,提出三维维纳增量滤波算法以及加快其收敛速度的方法。
Image restoration was applied in these result. This paper used Gaussian function as point spread function, applying in inverse filtering algorithm and Wiener filtering algorithm and improving them. It proves the effect of the improved Wiener filtering algorithms is better than inverse filtering improved algorithm. In addition, it proposed improved Wiener incremental filtering algorithm through theory.
