Image inpainting based on pyramids

Image inpainting is a technique used to automatically recover the damaged or missing regions in digital images or used to remove the unwanted objects from images. This paper presents a novel approach for recovering the damaged regions of digital images based on pyramids. The idea is to generate the pyramids of the image to the level where all the damaged pixels are fully eliminated. Then the damaged pixels are filled in from the bottom pyramid to the top. In pyramid image at level i, the damaged pixels are filled in from the EXPANDED pyramid image at level i -1, and so on up to the level 0 pyramid. The proposed technique has been tested over a large verity of images and shown excellent results to restore small damaged regions and satisfactory results for large damaged regions.
