Some Eye-Popping Research From Siggraph 135

Posted by kdawson
from the let's-face-it dept.
jamie found links to a discriminating selection of Siggraph papers at waxy.org. Among the more captivating: automatically improving the attractiveness of faces in portraits; automatic substitution of similar faces into photographs (with potential applications such as a privacy-enhanced Google Street View); and using still photographs to enhance video of a static scene.

      This is a typical slashdot comment. Uninformed, belittles others work. Symmetry might work in some pictures. It might not work in others. Besides, the feature extraction needed to establish symmetry is non trivial (its the same as what the author of the paper does). If this was so trivial, why didn't you build a system like this. The world belongs to the doers, not the "Ah, I told you so" crowd.

    I rotated the pairs of adjusted faces so they were left to right (and the faces were on their sides), and defocused my eyes as if I was looking at a 3D stereo pair of pictures to see what would happen. The slight differences made the portraits appear to me as if they had been photographed in 3D. The places that had been changed were subtly evident as a misalignment -- in the eyes of some, for example. I realize this is a fudged 3D effect, but might there be some use for it?

Considering that an apparently large portion of Slashdotters very much consider themselves rationalist who do not believe things without proper evidence, it seems weird to me that many simply believe what they see in the news. These past week (maybe 2) there were at least two cases circulating around the internet where it had been observed that CNN has used footage from one event, trying to pass it off as that of another event. And that's pretty low tech.

      News reports should be only be as trusted as logic can be applied to the report.

      Take for instance the recent story of a Russian sipper shooting at a reporter. A few questions came to my mind:

      • What kind of sniper takes such a shot and misses?
      • What kind of sniper misses, and doesn't take a second shot?
      • How does one tell the affiliation of a sniper? Do they sign their bullets or something?

        If they shoot at you, you can be sure it's the enemy. The sniper would have easily figured out which side the potential target was on.

        > Do they sign their bullets or something?

        Signing the bullet would have screwed up the ballistics. Snipers are extremely anal retentive when it comes to their rounds. They usually use hand loads and they buff the round to remove any imperfections.

  • I could not decide, which versions looked better. I only recognized that they ere mostly non that good looking on both fotos.

    Then I looked closer, because I know a bit about the methods behind it. And they did some big errors, like copying the one side of a face to the other, when the face did not look perfectly straight into the camera. This gave some weird results. Some faces even looked quite unnatural (especially, but not solely the focus on huge foreheads.

    The first two with the faces...none of them looked right after being touched up. That's probably because our brains are really really good at processing faces. They looked wrong, and creepy in some way to me. Not impressed with the results at all.

    The static scene improvements with photo's though. Wow. Fooled my eyes everytime. It always looked better and when they started swapping out elements, hiding posts so you could see the flowers behind, fixing the shaky video was the only thing that looked at li

    Making faces more attractive is easy. All you have to do to get a reasonable increase is to make them more symmetrical.

    If you want yet another increase, there is a set of ratios for distances between features that uncannily applies to pretty much everyone who is widely considered attractive. Shift everything closer to those ratios, and you'll get a big improvement.

    Want more? Fix skin blemishes.

    Between the three of those, you can make incredible strides. I would highly encourage any interested to watch "The Human Face".

    • It's about making faces more attractive automatically. Doing it manually is easier than writing a program that will do it for you

      I'd like to see the face beautification software applied to fifty of the most beautiful actresses in Hollywood. I'd like to how much more beautiful they get, but also if some of them lose their unique look that makes them attractive to some.

    Now she can look as good the morning after as she did the night before!

  • as the subject says, I found the female face more attractive but since I may own that probably doesn't mean anything. Now I know there aren't any females on Slashdot, but are there any fat geeks pretending to be girls that can say whether or not they found the male faces more attractive simply because they were "female".
  • Video does lie now.

    Can video ever be trusted again where evidence is concerned?

    Once again someone's trying to write a bloated piece of software to overcharge for something our systems already do.

    See the following example for how I was able to increase the attractiveness of an already attractive Hooters girl using only Microsoft Paint. (exported via Fireworks for filesize optimization)

  • A couple of items of interest displayed at Siggraph this year as well which I think have potential.

    Microsoft's come up with a way of painting objects onto an object extracted from a video, then reinserted to the video that remains accurate when the camera angle's changed. Their research paper's called Unwrap Mosaics [microsoft.com], and you can see a video on Youtube here [youtube.com] (higher quality video on the reseach page).
