摘要
振动退化图像的恢复算法面临的主要问题是在比较宽松的约束条件下对模糊图像的快速恢复.在对国内外的振动模糊图像恢复算法进行充分研究的前提下,提出一种快速有效的算法.首先应用伪白化叠加的方法得到与点扩展函数对应的调制传递函数,然后根据最小相位的理论,解线性方程组得到点扩展函数.在较少的约束条件下避免了传统算法循环迭代计算复杂、费时等缺点,实验结果表明,恢复效果较好,抗噪声能力强.
Abstract
The main problem of vibration blurred image restoration is how the restoration can be done under loose constraints. An effective and fast algorithm is proposed after algorithms of this field are investigated. Pseudo whitening method is applied to obtain Modulation Transfer Function(MTF) corresponding to Point Spread Function(PSF). Then PSF is obtained by solving equation set based on minimum phase theory. Under few constraints, the algorithm avoids the complexity and time-consuming of traditional iteration method. Experiments show this algorithm has high the efficiency and the ability of anti-noise.
