Face2Face: Real-time Face Capture and Reenactment of RGB Videos
We present a novel approach for real-time facial reenactment of a monocular target video sequence (e.g., Youtube video). The source sequence is also a monocular video stream, captured live with a commodity webcam. Our goal is to animate the facial expressions of the target video by a source actor and re-render the manipulated output video in a photo-realistic fashion. To this end, we first address the under-constrained problem of facial identity recovery from monocular video by non-rigid model-based bundling. At run time, we track facial expressions of both source and target video using a dense photometric consistency measure. Reenactment is then achieved by fast and efficient deformation transfer between source and target. The mouth interior that best matches the re-targeted expression is retrieved from the target sequence and warped to produce an accurate fit. Finally, we convincingly re-render the synthesized target face on top of the corresponding video stream such that it seamlessly blends with the real-world illumination. We demonstrate our method in a live setup, where Youtube videos are reenacted in real time. [video] [more]
The Chair for Computer Science 9 (Computer Graphics) works on the generation and manipulation of synthetic images, virtual worlds and computer animations with the help of computers.
This comprises methods for generating suitable models of the scene (geometric modeling), methods for displaying such scenes (image synthesis, rendering) as well as the processing of large data sets with aim to visualize the information content (scientific visualization). Our focus is on applications of computer graphics in medicine and engineering.
The Department was founded 1992 and currently employs 21 scientific assistants.
