Abstract
A simple method for segmenting eyes and extracting parameters enables further processing of the image to enable a person to appear to be making eye contact with another via a video conferencing system. This method is a first step for eye synthesis and gaze detection because it can automatically extract select eye parameters useful to these processes. Its advantage is that no a priori information is necessary to segment eyes, unlike modeling and neural network methods. The method of the present invention first blurs the image to make it easier to determine the location of the two eye regions in the image. The eyebrows are then eliminated based on the located eye regions. The eyes are then segmented and the eye parameters are extracted from the resulting image According to the present invention, the process applies a Gaussian filter, h(x, y), where g(x, y) is the resulting image and ƒ(x, y) is the original image.
