Abstract
Un codificador o decodificador de imagen incluye circuitería y una memoria. La circuitería, en operación, predice un primer conjunto de muestras para una primera división con uno o más vectores de movimiento que incluye un primer vector de movimiento y predice un segundo conjunto muestras para una primera porción de la primera división con uno o más vectores de movimiento de una segunda división. Las muestras del primer conjunto de muestras de la primera porción de la primera división y del segundo conjunto de muestras de la primera porción de la primera división son ponderadas. Un vector de movimiento para la primera porción de la primera división se almacena, que se basa en uno o ambos del primer vector de movimiento y el segundo vector de movimiento. La primera división se codifica o decodifica al usar al menos las muestras ponderadas de la primera porción de la primera división.
