A survey on inpainting techniques

Image inpainting is one of the image restoration technique used for reconstruction of lost or damaged region in an image. Images may contain distorted and undesired regions which are to be removed. The main objective of the inpainting algorithm is to replace these regions and fill up the holes in a natural way. The methods used for inpainting includes diffusion based, exemplar-based, hierarchical super-resolution-based and spatial patch blending methods. This paper aims at comparing the various techniques used for inpainting. These methods aim at hole filling and removing the artefacts such as texture garbage, blur effects and unconnected edges.
