Basic UML of program is as below,

• Functions to capture images from Laptop or external video Camera.
• Use Other OpenCv methods like cv2.face.EigenFaceRecognizer_create(),cv2.face.FisherFaceRecognizer_create()
• Rather tha using facial Haar Caascade we can use cascade for nose,eyes,mouth etc.(Less efficient)

• "FaceReco" file contains normal LBPH classifier which takes input from traningfiles and test to testimg
• "Facerecoadv" file contains abstract of how videocapture,timer,eigen-fisher algo can be used.
