Deepfake your dance moves with an AI body twice



A target dancer gets ingenious thanks to AI

You do not have trains like Beyonce. You have two left feet. People check that you're okay when you're on the dance floor.

It's okay to dance to the beat of another drum, but an AI system developed by University of California researchers, Berkeley, could give you moves worthy of Michael Jackson or even a prima ballerina.

It's reminiscent of AI-generated "Deepfake" videos that put one person's face on another's body, but this time it's all about the boogie.

Caroline Chan from Berkeley uploaded a video last week showing the AI ​​in action. The system is the subject of an article titled Everybody Dance Now (PDF). The team describes it as "a simple method for how I do" motion transfer. "

The AI ​​analyzes videos of a target dancer coming down and a video of someone who can really burn the dance floor. She translates the dancers into moving stick figures and then applies the gentle movements to the body of the target and creates a video that makes it look as if everyone could stylishly cut a rug.

"With our frame, we create a variety of videos, untrained amateurs can spin and spin like ballerinas, perform martial arts kicks or dance as dynamically as pop stars," the researchers write.

One of the demonstrations uses the movements of pop star Bruno Mars from his music video "That's What I Like" and lends his skills to two different target dancers.

The illusion is not perfect. You can see some ripple in the bodies of the dancers in the generated videos, but it's still a straightforward demonstration of what KI can do.

The word "Deepfake" does not appear anywhere in the paper. Deepfake videos that involve exchanging faces or changing a person's mouth to make it look like he's saying something he is not are a growing cause for concern.

Community Discussion Page Reddit has fought hard against the pornography of Deepfake earlier this year and the political world is concerned about the potential of disseminating disinformation through fake videos.

The Berkeley team's dance project is a lot of fun, but also illustrates the rapid progress in AI systems. It's a good reminder to question the validity of what you see online in videos. It may turn out that your cousin is not the second coming of Ginger Rogers.
