A method and system are presented for real time Super-Resolution image reconstruction. According to this technique, data indicative of a video frame sequence compressed by motion compensated compression technique is processed, and representations of one or more video objects (VOs) appearing in one or more frames of said video frame sequence are obtained. At least one of these representations is utilized as a reference representation and motion vectors, associating said representations with said at least one reference representation, are obtained from said data indicative of the video frame sequence. The representations and the motion vectors are processed, and pixel displacement maps are generated, each associating at least some pixels of one of the representations with locations on said at least one reference representation. The reference representation is re-sampled according to the sub-pixel accuracy of the displacement maps, and a re-sampled reference representation is obtained. Pixels of said representations are registered against the re-sampled reference representation according to the displacement maps, thereby providing super-resolved image of the reference representation of said one or more VOs.
