An effective 3D motion compensated extension of WienerChop model [Gha97a, Cho98a] for image sequences is presented. The proposed framework is based on a suitable combination of Wiener filter and wavelet transform and it can be shown to outperform the currently available techniques. Effectiveness combined with a low computational effort makes this approach very attractive and then it can be successfully employed in restoration of old movies
