Abstract
ESTE PROCEDIMIENTO ITERATIVO DE ESTIMACION DE MOVIMIENTO CONSISTE EN REALIZAR UN NUMERO FIJO DE ITERACIONES, CONSISTIENDO CADA ITERACION EN: MUESTREAR (8,9) LAS DOS IMAGENES CON UNA RESOLUCION CRECIENTE EN CADA ITERACION; AS CARACTERISTICAS EN LA IMAGEN DE REFERENCIA (11''); UN VECTOR DE MOVIMIENTO LOCAL (14'') PARA CADA MUESTRA CARACTERISTICA DE LA IMAGEN DE REFERENCIA, INICIALIZANDO ESTA ESTIMACION CON UN VECTOR DE DESPLAZAMIENTO DEDUCIDO DE UNA ESTIMACION DE MOVIMIENTO GLOBAL, REALIZADA DURANTE LA ITERACION PRECEDENTE A LA ITERACION EN CURSO; ENTO GLOBAL DE LA IMAGEN ACTIAL, CALCULANDO LOS VALORES DE LOS PARAMETROS DE UN MODELO (13''), A PARTIR DE VECTORES DE MOVIMIENTO LOCAL ESTIMADOS DURANTE LA ULTIMA ITERACION.
