STUDY OF EXEMPLAR BASED IMAGE INPAINTING TECHNIQUES

Image Inpainting refers to filling up the missing area (hole) of an image by using the information from surrounding’s (known area) such that the resultant image is logically accepted. OR it is a technique of altering the given image in such a way that the resultant image is undetectable by the ordinary observer. Image In-painting is very important and emerging field of research in image processing. It is the technique of repairing the disrupted /missing part of an image plus elimination of unwanted objects. It has wide range of applications-used in restoring the ancient paintings, removal of superimposed text like dates, subtitles, logos or publicity, repairing the damaged parts of photographs and films. In this paper we have discussed various inpainting techniques such as Texture synthesis, PDE based image inpainting, Examplar based image inpainting, Semi automatic image inpainting, Hybrid inpainting.
