Abstract
Un codificador de video y decodificador de video pueden determinar un conjunto de filtros de bucle adaptativo, de entre una pluralidad de conjuntos de filtros de bucle adaptativo, de una forma por bloque. Cada conjunto de filtros de bucle adaptativo puede incluir filtros de una imagen anterior, filtros señalizados para la imagen actual y/o filtro pre-entrenado. Al variar el conjunto de filtros de bucle adaptativo de una forma por bloque, los filtros de bucle adaptativo disponibles para cada bloque de datos de video se pueden adaptar más a las estadísticas locales de los datos de video.
