Abstract

Procedimiento para la detección de un movimiento dentro de una zona gráfica determinada de dos imágenes digitalizadas, presentando las siguientes fases: - división de las imágenes digitalizadas en segmentos con un tamaño determinado, - transformación (4) de los segmentos en el campo de frecuencia, transformándose cada segmento en una propia representación del campo de frecuencia, - comparación (9) de la cantidad de un porcentaje de frecuencia determinado de una representación del campo de frecuencia de los segmentos correspondientes de las dos imágenes y - detección de la existencia de un movimiento (10) si la diferencia de las cantidades de los porcentajes de frecuencia rebasa un valor determinado y - determinación de la posición del movimiento por medio de la posición del segmento, en la que se ha rebasado el valor, dentro de la imagen.
