Image inpainting under local coordinate system

Abstract

This chapter focus on the regular texture inpainting problem under local coordinate system. General variational image inpainting models perform well for cartoon images, but poor for textures. In this paper, a novel local inpainting model is proposed by combining the total variation and OABE algorithm. Firstly, the local direction of texture is obtained according to the neighborhood of damaged region, the local coordinate is set up via the local texture direction and its normal direction; then the local variational inpainting model is proposed in this coordinate. We give the discrete Gauss-Seidel algorithm for this model and numerical experiments. The results show that our algorithm perform well for the regular texture images, even for textures like "Y". © 2012 Springer Science+Business Media B.V.
