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 generar un bloque reconstruido para un bloque actual, determinar un límite objetivo para el bloque reconstruido, determinar un primer bloque objetivo y un segundo bloque objetivo basado en una muestra adyacente al límite objetivo, y realizar filtración de desbloqueo en la muestra adyacente al límite objetivo, basado en un modo de predicción de al menos uno del primer bloque objetivo o el segundo bloque objetivo. En este caso, un valor de la muestra adyacente al límite objetivo puede no ser cambiado basado en el modo de predicción de al menos uno del primer bloque objetivo o el segundo bloque objetivo siendo un modo de paletas.
