-#### Face detection on the video stream
-
-###### Does the preprocessing pipeline take as input the webcam video stream of minimum 20 sec and save in a separate folder at least 20 preprocessed\* images?
-
-###### Do all images contain a face?
-
-###### Are all images reshaped and centered on the face?
-
-###### Is the algorithm that detects the face imported via cv2?

-#### Hack the CNN - guidelines:
-
-The neural network trains by updating its weights given the training error. If an image is misclassified the neural network changes its weight to classify it correctly. The trick is to keep the neural network's weights unchanged and to modify the input pixels in order to force the neural network to predict the wanted class.
-This part is validated if:
-
-##### Choose an image from the database that gives more than 90% probability of `Happy`
-
-###### Does the neural network modify the input pixels to predict Sad?
-
-###### Can you recognize easily the chosen image? The modified image is SLIGHTLY changed. It means that you recognize very easily the original image.
-
-Here are three resources that detail similar approaches:
