    A texture synthesis approach to elastica inpainting



    We present a new, fully automatic technique for wire and scratch removal (inpainting) that works well in both textured and non-textured areas of an image. [Chan et al. 2002] introduced a technique for inpainting using an Euler’s elastica energy-based variational model that works well for repairing smooth areas of the image while maintaining edge detail. The technique is very slow (due to a stiff, 4th order PDE) and difficult to control. [Efros and Leung 1999] used texture synthesis techniques for inpainting and hole filling. This works well for areas of an image that contain repeating patterns.
