Abstract

Un método de filtración de la invención es un método de filtración para realizar el desbloqueo/filtración de un límite entre un bloque de IPCM y un bloque que no es de IPCM que son adyacentes entre sí. El método de filtración comprende: un paso (S401) que consiste en determinar un primer parámetro de cuantificación para el bloque que no es de IPCM; un paso (S402) que consiste en determinar, mediante el uso del primer parámetro de cuantificación, un segundo parámetro de cuantificación que corresponde al bloque de IPCM; un paso (S403) que consiste en determinar una intensidad de filtro mediante el uso del primer parámetro de cuantificación y el segundo parámetro de cuantificación; y un paso (S404) que consiste en realizar el desbloqueo/filtración del límite mediante el uso de la intensidad de filtro determinada.
