Abstract

Un decodificador de video configurado para obtener un primer bloque reconstruido de datos de video que incluye una primera muestra con un primer valor; aplicar filtrado de desbloqueo al primer bloque reconstruido para crear un bloque filtrado de desbloqueo; determinar un primer valor de recorte para la primera muestra con base en una ubicación de la primera muestra en relación con un límite del bloque reconstruido y con base en un tamaño del bloque reconstruido; comparar el primer valor de recorte a una cantidad de modificación con la primera muestra causada por el filtrado de desbloqueo; en respuesta a la cantidad de modificación con la primera muestra causada por el filtrado de desbloqueo siendo mayor que el primer valor de recorte, modificar el primer valor por el primer valor de recorte para determinar un primer valor filtrado para la primera muestra; y producir un bloque filtrado de desbloqueo de datos de video con la primera muestra que tiene el primer valor filtrado.
