Now you can just print the identity to the console, or use it for wherever your imagination takes you! Remember that this face recognition method and this face verification method are only reliable in the certain conditions that you train it for. So to obtain good recognition accuracy, you will need to ensure that the training set of each person covers the full range of lighting conditions, facial expressions, and angles that you expect to test with. The face preprocessing stage helped reduce some differences with lighting conditions and in-plane rotation (if the person tilts their head towards their left or right shoulder), but for other differences such as out-of-plane rotation (if the person turns their head towards the left-hand side or right-hand
side), it will only work if it is covered well in your training set.
