Novel approach for temporal filtering of MPEG distortions

Standard DCT -based video coding techniques perform good results in terms of data compaction, making feasible the use of digital video in several application frameworks. The price to pay is the introduction of annoying visual distortions/artefacts in the reconstructed video. The lower the encoding bit-rate, the larger the number of artefacts. Post-processing is a practical solution that achieves a visual enhancement of the compressed images after decoding. Some of the artefacts, such as blocking (tiled-effect aspect) and ringing (ghost effect) have already been widely studied.
