The extraction of facial contours from a facial image is a challenging problem in computer vision. We propose a new active contour model for extracting facial outline contours. Our model has three characteristics: axis symmetry constraint, dual scale edge filtering and iterative initialization. We implemented this method in our Automatical Facial Contour Extraction System, and tested it on 60 facial images. We show the advantage of this method for detecting facial outline contours by a psychological experiment.
