Abstract: The restoration can be viewed as a process that attempts to reconstruct or recover an image that has been degraded by using some a priori knowledge about the degradation phenomenon. The multiresolution support provides a suitable framework for noise filtering and image restoration by noise suppression. We present the algorithms GMNR, a generalization of the MNR algorithm based on the multiresolution support set for noise removal in case of arbitrary mean, and NFPCA. A comparative analysis of the performance of the algorithms GNMR and NFPCA is experimentally performed against the standard AMVR and MMSE.
