摘要： 在加权最小二乘的基础上,结合PDE正则化,提出了一种视频图像序列超分辨率重建的自适应滤波方法.详细讨论了运动补偿矩阵和权值矩阵的构成和性质,推导并给出了滤波器的递推公式.仿真试验表明该算法的重建结果相当有效,具有一定的自适应性和鲁棒性.

关键词: 超分辨率重建, 加权最小二乘, PDE正则化, 运动补偿, 图像处理, 各向异性演化

Abstract: An adaptive filter for video image sequence super resolution reconstruction is proposed on the basis of the weighted least square and PDE regularization in this paper.The motion compensation matrix and weighted matrix are thoroughly discussed and the recursive filter formula is deduced.Experimental results demonstrate the effectiveness of the proposed method which is both adaptive and robust.

Key words: WLS, super resolution reconstruction, PDE regularization, anisotropic diffusion, motion compensation, image processing
