To detect the face and facial features
1.) Importing the required Libraries 2.) Loading the pre-trained Classifier for each feature 3.) Defining a function which does the detections of facial features 4.) Face detection through webcam 5.) Calling the funtion for detection 6.) Previewing the live face detected video
I've used pretrained Classifiers, i.e haarcascade_frontalface_default (for detecting the face), haarcascade_righteye_2splits (for detecting the right eye), haarcascade_lefteye_2splits (for detecting the left eye), haarcascade_nose2 (for detecting the nose) and haarcascade_mouth (for detcting the mouth)
