Abstract

Se describe un sistema para la localizacion rápida de ojo con base en un filtro que utiliza la densidad de contraste horizontal relativamente alta de la region del ojo para determinar las posiciones del ojo en una imagen de escala de gris de una cara humana. El sistema comprende una cámara para explorar a un individuo y un procesador para realizar la filtracion requerida. La filtracion incluye un filtro de computacion de contraste horizontal, un filtro de determinacion de densidad de contraste horizontal, un razonamiento de geometría facial, y una determinacion de posicion del ojo y trabaja con varias formas de ojo, orientaciones de cara y otros factores tales como lentes o aun cuando los ojos están cerrados.
