Abstract

La presente invención se refiere a un método y aparato de codificación/decodificación de imagen. Un método de decodificación de imagen realizado por un aparato de decodificación de imagen puede comprender derivar un bloque reconstruido para un bloque actual, derivar un límite objetivo para el bloque reconstruido, determinar una longitud de filtro de un filtro de desbloqueo que será aplicado para el límite objetivo, y aplicar el filtro de desbloqueo para el límite objetivo basado en la longitud de filtro determinada. La longitud de filtro puede ser determinada basada en al menos una de una anchura o altura de un bloque de transformación adyacente al límite objetivo.
