Abstract
Esta solicitud se refiere a la codificación de datos de video que incluyen una pluralidad de muestras de imágenes de un fotograma de video. Cada muestra de imagen corresponde a una de una muestra de luminancia y una muestra de crominancia. Cada muestra de imagen se filtra con el uso de un filtro en bucle adaptativo que tiene una longitud de filtro y un conjunto de coeficientes de filtro. Un conjunto de muestras de imágenes relacionadas se identifica en la longitud de filtro de cada muestra de imagen. Para cada muestra de imagen relacionada se identifica un índice de valor de recorte respectivo y un coeficiente de filtro correspondiente. Una diferencia de cada muestra de imagen relacionada y la muestra de imagen respectiva se recorta con base en el índice de valor de recorte respectivo que corresponde con un valor límite de recorte respectivo igual a 2 a una potencia de un número de recorte respectivo. La muestra de imagen respectiva se modifica con la diferencia recortada de cada una de las muestras de imágenes relacionadas con base en el coeficiente de filtro respectivo.
