Abstract

Artefactos de bloqueo en un límite de bloque (1) entre un bloque (10) y un bloque vecino (20) en una trama de video se reducen al calcular un desplazamiento basado en valores de píxeles de pixeles (11, 13) en una línea (12) de píxeles (11, 13, 15, 17) en el bloque (10) y basándose en valores de píxeles de píxeles (21, 23) en una línea correspondiente (22) de píxeles (21, 23, 25, 27) en el bloque vecino (20). El desplazamiento se agrega al valor de píxel del píxel (11) más cercano al límite de bloque (1) en la línea (12) de píxeles (11, 13, 15, 17) y se resta del valor de píxel del píxel (21) más cercano al límite de bloque (1) en la línea correspondiente (22) de píxeles (21, 23, 25, 27). El filtro de desbloqueo resultante tiene buenas características de paso bajo y es eficiente para reducir el artefacto de bloqueo.
