Abstract

Un método de decodificación de imágenes capaz de reducir la carga de procesamiento incluye: obtener un indicador de control de límite para controlar conjuntamente una operación de filtro de desbloqueo y una operación de compensación adaptable de muestra para un límite de corte de un corte actual que es decodificado que está incluido en una representación visual codificada (S11); decodificar el corte actual (S12); realizar la operación de filtro de desbloqueo basada en el indicador de control de límite únicamente sobre por lo menos uno de un límite de corte superior o un límite de corte izquierdo de entre todos los límites de corte del corte actual que ha sido decodificado (S13); y realizar la operación de compensación adaptable de muestra dependiente del indicador de control de límite únicamente sobre por lo menos uno del límite de corte superior o el límite de corte izquierdo de entre todos los límites de corte del corte actual que ha sido decodificado (S14).
