An anonymous reader writes "Accurate face recognition is coming. Pittsburgh Pattern Recognition, a face recognition start-up spun out from Carnegie Mellon University, has posted a tech demo showing an analysis of the entire original Star Trek series using face recognition. The online visualization includes various annotated clips of the series with clickable thumbnails of each character's appearance. They also have a separate page showing the full data of all the prominent characters in every episode including extracting thumbnails of each appearance." Their software can recognize frontal or near-frontal face instances.

    About a year or two ago

    What I wanted was for face recognition software to become more general so you could search for movies using vague memories from your childhood:

    "Girl on boat", "Wheat field", "Yellow flag"

    With an advanced enough search engine, you could tag everything automatically.

    I didn't think of privacy concerns though, I guess thats a good point.

  • Machine recognition (facial or otherwise) is a lot easier in the lab setting, where you have a small pool of objects to recognize and a lot of data on each object. In typical non-lab settings, you have a large pool of objects to recognize and a small amount of data on each object, and your recognition rates (fp and fn) go south pretty quickly.
    • by ceoyoyo (59147)

      I think you mean TP and TN (true positive and true negative). FP and FN (false positive and false negative) are your MISrecognition rates. You want them to go south.

      All of Star Trek is a much better test than the usual two or three grad students who were unlucky enough to come into the lab that day test.

      • Thanks, I did mean TP/TN although they can of course be obtained from FP/FN and vice versa.

        A better test would be to see if the program recognizes Captain Kirk in Boston Legal or T.J. Hooker, assuming that the features it looks for are somewhat age invariant.

For example, in episode 53 at about 1:30 in the sample there is dialog between Spock, Kirk, and someone else. The camera angles are steady and consistent (other than people turning their head while talking) and sometimes the system does not recognize one of the characters after it did just a few se

  • There is nothing in principle bad about what is being demonstrated here. But let's be clear, this isn't a new step forward, this quality of facial recognition has been around for years (just ask Vegas).

    The biggest limitation on facial recognition is and has always been the data processing cost. In terms of that the technology is obviously getting more and more viable as hardware progresses.

      OCR is easy, obviously, with all the CAPTCHA news going around.

      Bullshit.

      OCRs typically boast 99% accuracy -- which sounds good until you realize that this means an error in every line or two of text.

      CAPTCHAs only need to be able to solve correctly a small percentage of the time to be effective -- even smaller, given humans can screw them up, too, and that problem is getting worse. So for example, Gmail couldn't just blacklist your IP for trying to register gmail accounts, without seeing quite a lot of abuse -- and botnets make IPs almost irrelevant anyway. But even 10% accuracy, which would result in absolutely unreadable OCR, would still mean that out of every 10 gmail accounts you attempt to sign up for, you get one fully functional account.

      Which is damned good, for a spammer.

      But, it's though that by about 2025 the number of transistors and speed of processors will be such as to rival the brain and after that point all bets are off. It will be an exciting 15 years in AI research.

      I'll place a bet: We don't currently understand the human brain very well. How do you suppose we'll be able to emulate it? And your guess of 15 years seems very optimistic...

      Put another way, if I gave you a brand-new, top-of-the-line computer -- for the sake of argument, let's say it's a fully loaded Mac Pro -- only with the hard drive completely formatted, could you make it do anything useful?

      I'll make it slightly more realistic. I'll give you what Linus Torvalds had: A copy of Minix and a C compiler. And of course, you've got more hardware than he does. Could you just write a modern OS?

      If you assume that the raw power will let us "evolve" an AI, I'm going to suggest that it takes much more hardware to evolve a program into being than it does to run it.

      But, if we imagine a conscious program we can imagine a being who can 'image' every moment of life (or of their brain), save it, and even rewind backwards, or stop and start states, easily. If you're an AI and you see something you don't want to remember, just rewind a bit and it's gone forever :P

      Yes, the last 15 years or more of science fiction -- cyberpunk, in particular -- make clear just how cool it would be for an AI to exist. That doesn't mean we're anywhere close.

      human intelligences uploaded into the machine

      Here's the uncomfortable truth: It may well be that we create AI, but no means to "upload" ourselves. Ever. The best we can do is create AI children.

      And they might not like us very much. See the other side of cyberpunk -- distopian futures with robotic overlords. (Terminator comes to mind.)

    If you don't want to be recognized by facial recognition software, wear black and white greasepaint. In Episode 70 [pittpatt.com] the actors playing Lokai and Bele are misidentified in a few scenes. The images are categorized by the black and white makeup rather than the actor. I'm not sure why Bele's face paint is reversed in some of the images. Did he look in a mirror or something, or did the video capture reverse it?

  • When a character rotates his head, so the camera gets the side, the recognition gets lost. The person then shows up as unknown. It sounds so simple to link a face that changes from known to unkown (rotating head) to each other, solving the unknown. Example is episode 66 at 6:53 where mccoy = unknown, when kirk moves in front of him, afterwards mccoy is known. There is a bit of a gap, but some reasonably smart algorithm should not be so difficult to cook up.
