发明名称 Förfarande för att filtrera digitaliska bilder och filtreringsanordning
摘要 <p>The invention relates to a method for reducing visual artefacts in a digital image, which is coded by blocks (B 1 , B 2 , B 3 , B 4 ) and then decoded. In the method filtering is performed to reduce visual artefacts due to a boundary (R 12 , R 13 , R 24 , R 34 ) between a current block and an adjacent block (B 1 , B 2 , B 3 , B 4 ). The filtering is performed after the current block (B 1 , B 2 , B 3 , B 4 ) is decoded and there is a boundary available for filtering between the current block and a previously decoded block.</p>
