Abstract
L’invention concerne une séquence vidéo codée comprenant une pluralité d'images pouvant être décodée. L’invention peut comprendre des premier et second blocs adjacents d'une image d'une séquence vidéo codée. Une ligne de pixels comprenant des pixels des premier et second blocs peut être définie comme s'étendant au-delà d’une limite entre les premier et second blocs. Une première valeur de référence peut être calculée sur la base d'un premier pixel des pixels provenant du premier bloc. Une seconde valeur de référence peut être calculée sur la base d'un second pixel des pixels provenant du second bloc. Des valeurs de pixel filtrées pour chaque pixel de la ligne de pixels entre le premier pixel et le second pixel peuvent être calculées à l'aide d'une interpolation sur la base des première et/ou seconde valeurs de référence. Des blocs filtrés peuvent être générés à l'aide des valeurs de pixel filtrées, et une séquence vidéo décodée peut être générée sur la base des blocs filtrés.
