We’ve had face-tracking software for a while now, with the Kinect, which has led to some cool real-time animation…
…but now researchers have built a face detection system that lets you impose your facial expressions on real people. The software uses a webcam to create a 3D model of your face in real time, then distorts it to fit the facial details in the target footage (of someone else’s face):
It’s not anywhere near the market yet, but it’s scarily good. I’m sure there’s already high-powered software out there for creating fake videos, but this looks like it could lower the barrier to entry significantly. Prepare to never believe anything you see again!
