Face detection is the first step in our facial expression recognition
system, to localize the face in the image. This step allows
an automatical labeling for facial feature points in a face image.
We use a real-time face detector proposed in [17] available in
OpenCV library [5] which represents an adapted version of the
original Viola-Jones face detector(figure 1-a).
The next step in the automatic facial points detection is to
determine the coarse position for each point. To achieve this, we
develop a fully automatic method using an anthropometric model
