Abstract

La presente invención se refiere al rendimiento del refinamiento de vectores de movimiento en un espacio de búsqueda para inter-predicción de multi-referencia. Se seleccionan dos o más imágenes de referencia, una de las utilizadas para el refinamiento de vectores de movimiento. Basándose en una estimación inicial de un vector de movimiento a la imagen de referencia para el refinamiento de vectores de movimiento, se construye un espacio de búsqueda en esta imagen de referencia. Al utilizar la coincidencia de plantillas, se refina el primer vector de movimiento. El segundo vector de movimiento para otra imagen de referencia se calcula utilizando su estimación inicial, la estimación inicial del primer vector de movimiento y el primer vector de movimiento refinado.
