摘要
由于TV（总体变分）修复模型不能满足“连接性准则”。针对这个问题，Chan和Shen提出了基于曲率驱动扩散（CDD）修复模型，该模型通过在TV模型的基础上引入曲率项，从而使得“连接性准则”得以满足，本文将对此模型以及离散实现方法进行分析，并用实验得出结论：CDD模型具备了修复较大的破损区域及细小边缘的能力。
The TV （Total Variational） inpainting model fails to realize the connectivity principle ,when the broken scale is larger than the width of the objective of the inpainting, the inpainting task will not be achieved. This has encouraged Chan and Shen to develop a new inpainting model which is founded on Curvature-Driven Diffusions（CDD）. The CDD model imports a curvature based on the TV model, thus, the model realizes the connectivity principle, This paper analysis the CDD model and its numerical implementation, moreover, demonstrates the applications of inpainting the large demain and minute edges.
