Researchers make Deepfake videos look even more realistic

  1. Researchers from Carnegie Mellon University and Facebook Reality Lab presented the Recycle-GAN system at the European Conference on Computer Vision (ECCV) in Germany. It builds on the generative adversarial network (GAN) AI algorithm that moves one style of image onto another. Recycle-GAN improves the system by lining up the frames from both videos using “not only spatial, but temporal information.” It also uses a discriminator that scores the consistency of the new video against the source material.

    “This additional information, accounting for changes over time, further constrains the process and produces better results,” wrote the researchers.

    In the YouTube clip, we can see how Stephen Colbert appears to repeat the same lines as John Oliver, with everything from head nodding, eyebrow raises, and the shape of his mouth being imitated. Another video shows the same process applied to a cartoon frog.

    The “unsupervised data-driven approach ” can also be used in ways that don’t involve faces, including blooming flowers, sunrises, sunsets, clouds, and wind. But it’s the transfer of human mannerisms that is most impressive, such as “John Oliver’s dimple while smiling, the shape of mouth characteristic of Donald Trump, and the facial mouth lines and smile of Stephen Colbert,” writes the researchers in a paper.

    In addition to Deep Fakes being used to spread fake news, it’s commonly used as a way of pasting celebrities’ faces onto adult movie stars’ bodies, thereby creating fake celeb pornography. Pornhub banned such clips earlier this year after Discord shut down a group that shared the videos.

    Last month, the Defense Department produced the first tools for catching deepfake videos.

    I wonder if this method could have been used to get a more convincing Tarkin or Leia in Rogue One.

    Won't be long before this will kill any kind of Video evidence in court ..... which will make it more likely for the courts to convict on the faintest circumstantial evidence there is, they we are ALL in for one heck of a ride!

    I'm not sure about this being a good idea.

    Documents have been able to be forged for hundreds of years. This hasn't made the rules of evidence obsolete.

    This is very troubling because it may create confusion. That's why it's all the more important to ensure validity. For instance, with documents, you need certification, under threat of perjury, a business document is accurate. You need direct testimony for anything intended for trial to be admitted. It is then up to the judge/jury to determine it's credibility.

    Very impressive, but I am not that concerned, as you can easily see its fake and non natural.
    Maybe in couple of years...
