Abstract

Se divulgan métodos y aparatos para codificación de video utilizando procesamiento de Filtro de Bucle Adaptable (ALF); de acuerdo con un método el procesamiento de ALF con límite virtual siempre es aplicado a la fila de CTU inferior sin considerar si la fila de CTU inferior es para una imagen o una sub-imagen; en otro método, el proceso de relleno de ALF es unificado para diferentes tipos de límite pertenecientes al límite objetivo que pertenece a un grupo de tipo de límite comprendiendo dos o más de límite de segmento, límite de mosaico, límite de cara VR360, y límite de sub-imagen; en otro método todavía, el procesamiento de ALF VB tiene una prioridad fija para una región de esquina en que se pueden aplicar ambos límites virtuales horizontales y verticales.
