Abstract

EL PROCEDIMIENTO CONSISTE EN ESTIMAR EL MOVIMIENTO POR EJECUCION DE UN ALGORITMO DE GRADIENTE (2,3) QUE HACE MINIMA LA SEPARACION CUADRATICA DE LAS VARIACIONES LOCALES DE LUMINANCIA DEL PUNTO ACTUAL DE LA IMAGEN CON EL PUNTO QUE SE LE HA HOMOLOGADO EN LA IMAGEN PRECEDENTE, EN INICIALIZAR (7) LA EJECUCION DEL ALGORITMO MEDIANTE UNOS VALORES DE DESPLAZAMIENTO ESTIMADOS SEGUN VARIAS DIRECCIONES EN EL INTERIOR DE LA PROXIMIDAD MAS CERCANA CAUSAL DEL PUNTO ACTUAL Y MEDIANTE UN VECTOR INICIAL DE PREDICCION TEMPORAL DEL DESPLAZAMIENTO ENTRE TRAMAS SUCESIVAS DE LA IMAGEN TRAS HABER PROPAGADO CADA ESTIMACION EN EL SENTIDO DEL BARRIDO DE LAS LINEAS DE IMAGEN. APLICACION EN TELEVISION NUMERICA DE ALTA DEFINICION.
