摘要

为了改善运动模糊图像复原的效果

构造了基于l

高阶全变差的盲复原数学模型。该模型在l

稀疏先验的基础上

引入了可降低振铃效应的高阶全变差正则化约束项

用以解决低阶全变差造成的虚假边缘问题。盲复原算法首先用半二次分裂对数学模型求解

然后根据先验信息对模型解约束

多次迭代得到中间潜像、模糊核

最后采用非盲从复原算法恢复图像。实验结果表明:提出的方法可突出边缘结构特征

有效改善盲复原图像的效果。

Abstract

In order to improve the restoration effect of motion fuzzy images

a blind restoration mathematical model based on high-order total variation is constructed. Based on sparse priori

the regularization constraint term of high-order total variation which can reduce the ringing effect is introduced to solve the false edge problem caused by low-order total variation. The blind restoration algorithm first solves the mathematical model by semi-quadratic splitting

then constrains the solution of the model according to prior information

and obtains the intermediate latent image and fuzzy kernel through multiple iterations. Finally

the non-blind restoration algorithm is used to restore the image. Experimental results show that the proposed method can highlight the edge structure features and improve the blind restoration image effect effectively.
