一种结合全局一致性与局部连续性的壁画修复方法

提出了一种全局一致性和局部连续性结合的壁画修复算法.主要利用线性系统和图像修复间所蕴含的关系，构建具有全局过完备特性的相似块集合字典，同时构造弹性网正则化下的稀疏修复模型，并用同伦-最小角回归法求解出过完备字典下的稀疏系数；通过字典与系数的线性组合，得到待修复区域的全局特征；之后提出一种基于领域相似特性的局部特征估计方...

A Global Uniform and Local Continuity RepairMethod for Murals Inpainting

This paper proposes a global uniform and local continuity repair method for mural image inpainting.It uses the relationship between linear system and image repair to construct the similarity-preserving overcompletedictionary with global weighted feature. Meanwhile, a novel sparse repair model with elastic net regularization basedon similarity-preserving overcomplete dictionary is formulated to enhance the global feature consistency, and then anestimated method of neighborhood similarity is presented to guarantee local feature consistency, finally, a global fea?ture patch and local feature patch weighted method are applied to obtain the target patch. Experimental results ondamaged murals demonstrate the proposed method outperforms state-of-the-art inpainting methods.
