Abstract

Métodos y aparatos de codificación incluyen aplicar un procesamiento de filtro de bucle adaptable de componente cruzado (CCALF) en una imagen actual con base en coeficientes de CCALF señalizados en uno o más Conjuntos de Parámetros de Adaptación (APSs) de Filtro de Bucle Adaptable (ALF) para refinar uno o más componentes de croma de acuerdo con un componente luma, señalizando dos indicadores de señal ALF y dos indicadores de señal CCALF en cada APS ALF o analizando dos indicadores de señal ALF y dos indicadores de señal CCALF de cada APS ALF, y codificando o decodificando la imagen actual. Valores de los dos indicadores de señal ALF y los dos indicadores de señal CCALF en cada APS ALF no son todos iguales a 0 para garantizar que ninguno del APS ALF sea un APS vacío.
