一种新的基于倒谱法和Richardson-Lucy算法的运动图像盲复原方法

运动图像的盲复原,一直是图像处理领域的难点,本文根据运动模糊图像特点,提出了一种鲁棒、高效保留图像细节和纹理特征的图像盲复原算法.在图像的复原过程中运用了基于最大似然函数的Richardson-Lucy滤波方法只需知道模糊类型,不需要其它任何先验知识,就能做到有效复原,适用范围广,能对线性匀速运动类型的模糊、振动模糊、旋转模糊都有效,鲁棒性好,抗噪能力强.

A New Method of Blind Restoration of Motion Image Based on Cepstrum Method and Algorithm of Richardson-Lucy

Blind restoration of motion image always is a challenging problem in image processing.the paper,in view of the characteristic of motion image,puts forward a algorithm of blind restoration of motion image with good robustness and preserving image details and texture characteristic efficiently.The algorithm applys Richardson-Lucy filter based on the maximum-likelihood function during image restoration.It can restore efficiently a motion blurred image without any prior knowledge as long as the type of blur is known,its applicability for processing motion blurred images has a more wide range including the uniform linear motion images,vibration blurred images and rotation blurred images and it has a good robustness,strong anti-noise ability.
