Abstract :
Traditional ENG technology got the recording from the eye movement displacement parameters through contacting with skin indirectly. Modern nystagmus gets the eye movement image through video camera, then calculates the eye movement displacement parameters. Difficulties of this technology in so big noise image environment, are how to judge the accurate location of the pupil and how to measure the eye rotational angle. In this paper,we use the template matching method to solve how to judge the accurate positioning pupil in case of large noise image environment, followed by the use of mutual information in image registration to solve the problem of measuration of the eye rotational angle.We test these two methods in the simulated test images ,and the results are content.
