This paper shows an extraction method of a symmetric object for eyeglass face analysis using an active contour model. A contour of eyeglasses hinders a face analysis and synthesis which treats contours of facial parts or partial regions of the face such as eyes, mouth, cheek, eyelid and so on. Methods of active contours extract object contour well. We show an active contour model which is adapted to extract a contour of symmetric object, especially we focus on extracting eyeglass frame using snakes. We study to obtain parameters of snakes by genetic algorithm. We show the good results of applying the snakes in an actual facial image, and synthesize an expressive face with eyeglasses as an application.
