Abstract
A method and image processing system are disclosed that extract facial feature information from an image using biometrics information of a face. Regions of interests such as a face, eyes, nose and mouth are defined in the image. A combination of disparity mapping, edge detection and filtering are then used to extract coordinates/positions of the facial features in the regions of interest.
