AI Can Generate a 3D Model of a Person After Watching a Few Seconds of Video (sciencemag.org) 43

An anonymous reader shares a report: A new algorithm creates 3D models using standard video footage from one angle. The system has three stages. First, it analyzes a video a few seconds long of someone moving -- preferably turning 360-degree to show all sides -- and for each frame creates a silhouette separating the person from the background. Based on machine learning techniques -- in which computers learn a task from many examples -- it roughly estimates the 3D body shape and location of joints. In the second stage, it "unposes" the virtual human created from each frame, making them all stand with arms out in a T shape, and combines information about the T-posed people into one, more accurate model. Finally, in the third stage, it applies color and texture to the model based on recorded hair, clothing, and skin.

  • Assuming that it can be made to run on home computers, that is.
  • Based on the video, what we should really be working on is how to make such models move like a real human.

      There exists some pretty compelling research on having a 3d model walk a complicated terrain in a natural looking fashion.

      But I was unable to find the video :(. It probably isn't older than a year or so..

    Doesn't seem like it has much to do with artificial intelligence.

    Neat scanner program, though.

    • Presumably, this is domain-specific: it seems to use the limited information available to solve a constraint problem. So it's not just a scanner program.
  • ...In the next stage the system uses the phenotype information shown in the video combined with the 99.9999% shared genetic information between all humans to create a nearly exact genome for the person. ...In the final step the AI system uses your likes, preferences, cookie trails and other information gleaned from your online life to fill in the life experience portion and recreate your personality.

    This all allows the marketers to then pinpoint your exact weaknesses to advertising so that you BUY, BUY, BUY

      You've got two [wikipedia.org] different [wikia.com] Futurama episodes mashed together there. Seriously, do yourself a favor and brush up on our religious texts [theinfosphere.org].

  • Jesus... Everything is AI these days. That's like calling a newborn baby making fart noises a classical musician. At best, the baby could be employed for background music in mumble rap songs. A classical musician? Heavens no.

      Watching a video and from that being able to build a 3d model of a person.... ....is something that normally requires intelligence. Rocks can't do it. Neither can plants. Nor steam engines.

      This fits the definition of Artificial Intelligence exactly.

      You just have some kind of chip on your shoulder.

  • This is one step closer to the computer generated porn.

    • It isn't useful till it can differentiate the booty between Jessica Alba in Idle Hands and Jessica Biel. Until then body modeling is only a vague suggestion that people are different.

      Locating the joints automatically is nust a step above marking them manually and using a generic body.

  • This is actually one of the advances I had predicted many years ago. The next steps are interesting but ultimately you end up with what I refer to as "Rapid Physical Modeling" where in you can take an object, do a quick 360 view of it and then capture it's physical properties by manipulating it. A simple example is demonstrating how a potted plant can bend and it's ability to bend and spring back are inferred. The obvious benefit of this is that you can quickly model things with complex interactive respo

  • Even the summary describes it as a [learning] algorithm. Yes, it's bloody impressive, but it's an algorithm tuned to execute one specific task. If anything it's an Artificial Savant [wikipedia.org].

    That's not one angle, then, is it?

Think of it! With VLSI we can pack 100 ENIACs in 1 sq. cm.!

Working...
