Abstract

La présente invention se rapporte à un procédé de réduction des artéfacts de blocage associés à des pixels consécutifs d'une limite de bloc d'une image, telle qu'une trame vidéo. Les valeurs de pixels des pixels sélectionnés dans un premier bloc et dans au moins un bloc voisin, situé sur les côtés opposés d'une limite de bloc, sont évaluées. Un premier décalage pour les deux pixels de chaque bloc situé près de la limite de bloc est calculé, après quoi le premier décalage est comparé à une première valeur seuil. Si abs[premier décalage]
