Face Recognition using Kinect

Question

Is there any algorithm face recognition using the points getting from the "Face Tracking Basics" given by Microsoft?  Now I am using the below code. But I am not getting a correct value for (int i = 0; i < this.facePoints.Count - 1; i++){ Total += ((facePoints[i].Y + facePoints[i+1].Y) / (facePoints[i].Y -facePoints [i+1].Y)); }
