Abstract	In this paper the potential improvements by temporal coding artifact reduction are discussed. Whereas conventional spatial methods may suffer from flicker in the processed output due to variable intra frame processing or insufficient removal of coding artifacts, the temporal strategies are capable of flicker reduction and even re-establishment of details missing in the actual input frame. In addition to several temporal filter strategies a new concept for estimating the true motion over multiple input frames is proposed. As a result an image content adaptive spatio-temporal artifact reduction system is presented yielding an even higher output quality.
