Face2Face: Real-Time Face Capture and Reenactment of RGB Videos
Face2Face is an approach for real-time facial reenactment of a monocular target video sequence. Our goal is to animate the facial expressions of the target video by a source actor and re-render the manipulated output video in…

Technical Perspective: Photorealistic Facial Digitization and Manipulation
If facial performance capture is possible for conventional RGB videos in real time, then believable facial expressions can be transferred effortlessly from one person to another in a live-action scenario. This capability is demonstrated…
