Abstract
Se proporciona un método de desbloqueo, para desbloquear un límite de subparticiones dentro de un bloque de codificación en una codificación de imagen y/o decodificación de imagen, en donde el bloque de codificación actual se codifica en un modo de intrapredicción y el bloque de codificación actual se particiona en subparticiones que comprenden una primera subpartición y una segunda subpartición la cual está adyacente a la primera subpartición; en donde el método comprende: determinar una longitud máxima de filtro a ser 1 para una primera/segunda subpartición cuando un ancho de la primera o segunda subpartición son 4 muestras, o cuando una altura de la primera o segunda subpartición son 4 muestras; modificar un valor de hasta una muestra de la primera o segunda subpartición, en donde la hasta una muestra se obtiene de una fila o columna de la primera o segunda subpartición que es perpendicular y adyacente al límite de subparticiones entre la primera subpartición y la segunda subpartición. La presente divulgación permite modificar un número menor de valores de muestra en el límite de subparticiones y, por tanto, el método puede reducir los artefactos de bloque que pueden ser causados por los límites de subparticiones en el bloque de codificación actual que se aplica con una herramienta de intrasubpartición (Intra sub-partition, ISP).
