以TV模型为例的西藏壁画数字图像修复技术研究

Research of Tibet mural digital images inpainting using TV model

通过介绍图像修复技术中的一个主要修复模型,即基于偏微分方程的图像修复技术,具体分析了数字图像的的破损类型及对应方法,在偏微分方程的基础上,深入了解此模型中具有代表性的TV图像修复模型。分析TV模型在噪声影响下对修复方程的约束,实现对噪声图像的处理方法。分析和对比此类模型对不同破损图像的修复效果,得出了最佳修复方案。

By introducing a main image inpainting model that is image inpainting based on partial differential equations, particularly,Analyse the damage type and corresponding method of digital image , make an in-depth understanding of this model that is representative of the TV image inpainting model on the basis of partial differential equations. Analyse the TV models on the fix constraint equations under the influence of noise and achieve the processing methods for the noise of image. Analyse the repairing effect of the different types of outworn images and contrast through this model, conclude the best repair programme.
