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.)...
