Improve Face Recognition

Try to implement different algorithms to make the system more efficient

The face recognition was improved by, every time an authentication is done successfully, the user model is retrained using the captured frame. However some limitations still stand, namely:

• the light conditions of the environment affect the success rate of the authentication;
• users using glasses have a lower success rate due to light reflection in the lenses;
• high quality videos can sometimes be used to bypass the liveliness detection implemented;
