A patch-based approach for random-valued impulse noise removal

Julie Delon, Agnès Desolneux

Abstract: In this paper, we show that a patch-based approach can successfully be applied for impulse noise removal. This requires careful choices for both the distance between patches and for the statistical estimator of the original patch. This method proves to be particularly powerful, especially for the restoration of textured areas, and compares favorably to recent restoration methods.
