|Abstract:||A new class of image information-restoration algorithms virtually different from traditional techniques are proposed. In comparison with other approaches, our methods not only use the information in local areas, but also that in the remote regions in the image. The methods originate from the idea that there exists abundant long-range correlation within natural images and the human vision systems composed of our eyes and brains can sufficiently utilize such types of information redundancy to implement the functions of image interpretation, representation, restoration, enhancement, and error concealment. Our general approach can be summarized as five basic steps: fetching, searching, matching, competing, and recovering. The experimental results on several practical applications show that our methods perform substantially better than many other state-of-the-art methods.|
