Abstract

Se divulgan métodos y aparatos para el procesamiento de filtro de bucle de video reconstruido. De acuerdo con este método, si un filtro de bucle no se permite para un límite objetivo, el filtro de bucle objetivo se deshabilita en la parte superior, parte inferior, izquierda y derecha del límite objetivo. De acuerdo con otro método, la forma de CC-ALF (Filtro de bucle adaptativo de componentes cruzados) se cambia a través de un límite vertical. De acuerdo con aun otro método, CC-ALF y ALF de luma manejan muestras no disponibles de la misma manera.
