Blind Restoration of Blurred Image Based on Precise Extraction of 2-D GCD
-
摘要: 利用2-D公共因子(GCD)提取是实现图像盲复原最有效的方法之一。该文发展了一种2-D公共因子精确提取算法，该算法不需要构建原算法中高阶病态方程，其复杂度大大降低，且提高了对噪声的鲁棒性。仿真实验证实了该文提出的方法优于传统图像复原算法。

Abstract: In this paper, the issue of blind image restoration is considered by using 2-D Great Common Divisor (GCD) extraction approach. A precise extraction algorithm of 2-D GCD is proposed. Since no high order ill-posed equation is needed, calculation complexity and noise robustness for the algorithm are improved. Simulation result shows that the proposed algorithm is able to provide a better performance than traditional algorithm. -
