The filter is intended for recovering an old film by removing vertical scratches, noise, tapes defects and other artifacts that can be met in an old cinema. Now we are working on the processing speed acceleration and improvement of "detail-garbage" choice criteria.

Besides providing cardinally better visual quality, the filter greatly facilitates compression. By our measurements the compression ratio of DivX compressed movie pre-processed by this filter increases by up to 3 times with better visual quality.

Examples

Let's consider job of the filter on the test sequences "4msu".
