Deepfake your dance moves with an AI body

A goal dancer gets some nice skills thanks to AI.

You do not have features like Beyonce. You have two left feet. People are checking if you feel OK when you are on the dance floor.

It's ok to dance at the beat of another drum, but an AI system developed by researchers at the University of California, Berkeley, can give you treats worthy of Michael Jackson or even a nice ballerina.

It's reminiscent of AI-generated "deepfake" videos that put the face of someone else's body, but this time it's about boogie.

Berkeley Caroline Chan uploaded a video last week showing AI in action. The system is subject to a paper called Everybody Dance Now (PDF). The team describes it as "a simple method of" doing as I do "movement transfer."

AI analyzes videos of both a target dancer coming down and a source video of someone who can really burn up the dance floor. It transfers the dancers to removable stick figures and then puts the smooth movements on the target's body and generates a video that makes it seem that someone can cut a carpet in style.

"With our framework we make a number of videos that allow unskilled amateurs to spin and spin like ballerinas, perform martial arts kicking or dancing as alive as pop stars," the researchers wrote.

One of the demonstrations uses the pop star Bruno Mars's feature from his. It's what I like music video and gives his skills to two different target dancers.

The illusion is not perfect. You can see some waviness in the dancer's body in the generated videos, but it's still a slim demonstration of what AI can do.

The word "deepfake" does not appear anywhere in the paper. Deepfake videos that involve face-swapping or changing a person's mouth to make it seem as if he says something he is not a growing cause of concern.

Social Disclosure Reddit exploded in deep-science earlier this year, and the political world is concerned about the possibilities of spreading disinformation through fake videos.

The Berkeley team's dance project is extremely fun, but also illustrates the rapid progress in AI systems. It is a good reminder to ask questions about the validity of what you see in online videos. It may turn out that your cousin is not the other, Ginger Rogers comes after all.
