Abstract

Exemplar-based inpainting techniques demonstrate some advantages in filling both textural and structural images, based upon the simple process of patch sampling and copying. An implicit assumption of such methods is that an exemplar patch could be found for copying. But the assumption might be false for images with complex structures, resulting in inpainting artefact. To inpaint structure and texture more efficiently, this paper adopts a weak assumption that affine transformed patches could be found for filling unknown regions. The algorithm based on this assumption firstly establishes the affine relation between the unknown region and a source patch, then transform the source pixels to fill the unknowns. This algorithm generates more satisfying inpainting results, as illustrated by the provided experiments.
