Imagine looking into a mirror, but not to see your own face. Instead, you are looking in the eyes of Barack Obama or Angela Merkel. Your facial expressions are seamlessly transferred to that other person's face in real time.
The TNG Hardware Hacking Team has managed to create a prototype that transfers faces from one person to another in real time based on Deepfakes. Neural networks detect faces within a video input, then translate them and integrate them back to the video output. Through this technique it is possible to project deceptively real imitations onto other people.
