Abstract

Se divulgan métodos y aparatos para el procesamiento de filtro de bucle de video reconstruido. De acuerdo con un método, se utilizan múltiples filtros CC-ALF (filtro de bucle adaptativo de componentes cruzados). La selección de los múltiples filtros CC-ALF se puede señalizar en un APS (conjunto de parámetros de adaptación). De acuerdo con otro método, el CC-ALF se puede implementar de acuerdo con la diferencia entre una muestra que se va a procesar y su muestra vecina.
