A.I. can now create fake videos of people from a single picture

Researchers advance machine learning to create videos of people from single stills and paintings.

Samsung
  • Samsung researchers improve AI modeling to quickly create realistic (but fake) videos.
  • The model uses "single-shot learning" to create videos from a single picture.
  • The application of the tech could be in telepresence, video conferencing and gaming.

An AI can now take a single picture of a person's face and animate it convincingly. This can lead to animating paintings and photos but also add to the mistrust of images and deepfakes online.

The new method from researchers at the Samsung AI Center in Moscow incorporates facial landmarks from a source face into the facial data from the target face to animate it. The target face will do anything done by the source face, which can be any talking head.

What is different here from previous technology that has been developed to achieve this is the fact that rather than needing a lot of data (like video) to analyze, this approach called "single-shot learning" needs just one image of a person's face. The video that is generated from that can show the face making a range of expressions and speaking with reasonable credibility.

The new tech front loads the process of facial landmark recognition with a large amount of data from a bank of talking head videos. It then trains the model to be very efficient in connecting parts of the target face with the source.

The new AI also uses the Generative Adversarial Network, having two models compete against each other in creating a more "real" result.

Here’s how adversarial learning works:

Where can you use this technology, other than contributing to the epidemic of fake news that is sure to eventually affect personal relationships as much as the national conversations? "Such ability has practical applications for telepresence, including videoconferencing and multi-player games, as well as [the] special effects industry," Samsung said.

Leonardo da Vinci could visually flip between dimensions, neuroscientist claims

A neuroscientist argues that da Vinci shared a disorder with Picasso and Rembrandt.

  • A neuroscientist at the City University of London proposes that Leonardo da Vinci may have had exotropia, allowing him to see the world with impaired depth perception.
  • If true, it means that Da Vinci would have been able to see the images he wanted to paint as they would have appeared on a flat surface.
  • The finding reminds us that sometimes looking at the world in a different way can have fantastic results.

Culture & Religion
  • Religious people tend to have more children than secular people, but why remains unknown.
  • A new study suggests that the social circles provided by regular church going make raising kids easier.
  • Conversely, having a large secular social group made women less likely to have children.
