Abstract

Se describen dispositivos, sistemas y métodos para el procesamiento de video. En un aspecto ejemplar, un método para el procesamiento de video incluye codificar una unidad de video de un video como una unidad de video codificada; generar muestras de reconstrucción a partir de la unidad de video codificada; realizar una operación de recorte en las muestras de reconstrucción, en donde un parámetro de recorte utilizado en la operación de recorte es una función de un índice de recorte y una profundidad de bits de las muestras de reconstrucción o una profundidad de bits de las muestras de la unidad de video; aplicar un filtro de bucle adaptativo no lineal a una salida de la operación de recorte; y generar una representación codificada del video usando la unidad de video codificada.
