Abstract

Se describe un método para procesamiento de video. El método incluye determinar, para una conversión entre una unidad de video de un video y una representación de flujo de bits del video, si se permite que un proceso de relleno especular rellene una muestra luma indisponible durante una aplicación de una herramienta de filtrado de circuito a la unidad de video; y realizar la conversión basada en la determinación.
