Facial features extraction is one of the essential techniques in automated visual interpretation and recognition of human faces. According to the basic theory

methods and techniques of active contour/snake model

a series of algorithms are presented. In this paper

facial features are described accurately about contour but not express simpllely with datas. In the experiments

the contours of eye are captured by deformable template model

the shapes of the eyebrow are extracted by active contour/snake model and the results show that using the algorithms for facial feature extraction can get good adaptability and robustness.
