Researchers at Stanford University, working with colleagues at the Technical University of Munich in Germany, the University of Bath in the U.K., France-based Technicolor, and other institutions have developed an artificial intelligence-based system that uses input video to create photorealistic reanimations of portrait videos.

The data from the source videos, which are created by a source actor, is used to manipulate the portrait video of a target actor.

In addition, the new Deep Video Portraits systems enables a range of movements, including full three-dimensional head positions, head rotation, eye gaze, and eye blinking.

Deep Video Portraits uses generative neural networks to take data from the signal models and calculate the photorealistic frames for a given target actor; secondary algorithms are used to correct glitches, giving the videos a highly realistic appearance.

The research will be presented in August at the ACM Special Interest Group on Computer Graphics and Interactive Techniques Conference (SIGGRAPH 2018) in Vancouver, Canada.
