Abstract

Un sistema y método de codificación inter en donde se emplea la coincidencia de plantillas de tamaño variable. Una plantilla superior, una plantilla izquierda y una plantilla superior-izquierda pueden definirse en donde el ancho de la plantilla superior es igual al ancho del bloque de codificación, la altura de la plantilla izquierda es igual a la altura del bloque de codificación, pero las segundas dimensiones (altura y ancho) de las plantillas son variables. Luego se identifica una mejor coincidencia entre el bloque de codificación actual y el bloque de codificación luego se codifica mediante el uso de FRUC.
