....In this section we review, briefly, previous work on face image interpretation and coding. Comprehensive reviews for these topics can be found elsewhere [17,20] 2.1: Locating Facial Features Methods based on deformable templates have proved useful for locating facial features. Kass et al. [12] describe the use of active contour models snakes for tracking lips in image sequences. They initialise a snake on the lips in a face image and show that it is able to accurately track lip movements. Because snakes do not incorporate prior knowledge about expected shapes, this approach is ....
