Abstract

Un codificador de video está configurado para codificar un índice de recorte del filtro de bucle adaptativo (ALF) como un entero sin signo de longitud fija. El codificador de video puede aplicar, con base en el índice de recorte del ALF, un ALF a un bloque de imagen de los datos de video.
