Everybody Dance Now - Deepfakes for Dancing

6 years 2 months 3 weeks ago

via https://www.theverge.com/2018/8/26/17778792/deepfakes-video-dancing-ai-synthesis :

Artificial intelligence is proving to be a very capable tool when it comes to manipulating videos of people. Face-swapping deepfakes have been the most visible example, but new applications are being found every day. The latest? Call it deepfakes for dancing. It uses AI to read someone’s dance moves and copy them on to a target body.

The actual science here was done by a quartet of researchers from UC Berkley. As they describe in a paper posted on arXiV, their system is comprised of a number of discrete steps. First, a video of the target is recorded, and a sub-program turns their movements into a stick figure. (Quite of a lot of video is needed to get a good-quality transfer: around 20 minutes of footage at 120 frames per second.) Then, a source video is found and a stick figure made of their movements. Then, the swap happens, with a neural network synthesizing video of the target individual based on the stick figure movements of source.
