Facial feature detection with OpenCV with eyes and mouth corners points

edit

I'm working on a face feature detection project and I do detect the eyes, nose and mouth using OpenCv withHaarcascade xml files. But, I want to have the eyes and mouth corners points and the nose center. The goal is using it to predict emotions. I found this link that shows how it works, and I need to get to this result using JAVA. Could any one help me?

Thanks in advance.

in this part we receve the face image and we drawRect on the face:

 public void drawFaces(BufferedImage image) {  
    final List<PotentialFace> faces = FacialRecognition.run(image, db);  
    if (faces.isEmpty()) {  
      return;  
    }  
    Graphics2D g2 = image.createGraphics();  
    g2.setStroke(new BasicStroke(2));  
    currentFaces.clear();  
    for (PotentialFace face : faces) {  
      final Rectangle r = face.box;  
      final Color c1, c2;  
      final String msg;  
      if (face.name == null) {  
        c1 = c2 = new Color(scale(r.x, getWidth(), 255d), scale(r.y, getHeight(), 255d), 0).brighter();  
        msg = "Click to tag";  
      } else {  
        c1 = new Color(face.name.hashCode()).brighter();  
        c2 = new Color((int) (c1.getRGB() - 10*face.confidence));  
        msg = String.format("%s: %f", face.name, face.confidence);  
      }  
      g2.setColor(c1);  
      g2.drawRect(r.x, r.y, r.width, r.height); 
      g2.setColor(c2);  
      g2.drawString(msg, r.x + 5, r.y - 5);  
      currentFaces.add(r);  
    }
