Abstract
Se proporciona un método de predicción de movimiento. Primero, se determina una pluralidad de unidades candidato que corresponden a una trama actual. Luego se obtiene una pluralidad de vectores de movimiento de las unidades candidato. Luego se calcula una pluralidad de factores de escala temporal de las unidades candidato de acuerdo con una pluralidad de distancias temporales entre tramas de referencia de los vectores de movimiento y la trama actual. Luego se escalan los vectores de movimiento de las unidades candidato de acuerdo con los factores de escala temporal para obtener una pluralidad de vectores de movimiento escalado. Finalmente, se selecciona un predictor de vector de movimiento para la predicción de movimiento de la unidad actual de las unidades candidato de acuerdo con los vectores de movimiento escalado.
