    Tell me, which is easier? Upload this image [iclod.com] and try to find out where you are via this Visual Google, or enter the street name (street sign in the photo says "Queen Street") in Text Google?

    The article also mentioned this thing should start small, like a movie guide, so is it easier to upload a 2K "I,Robot" billboard photo, or just enter "I,Robot" in Google on your cell phone?

    As long as human input is still required (i.e. you need to submit something), I don't think this is going to be popular. However, if you have a Oakley that automatically takes photos of what you see and feeds you the location details, that'll be something.

    • It does seem to have some functionality though. Let's say for example, this holiday I received a Thing(tm) as a present. I could take a picture or two of the Thing, and it may be easier to figure out what the it is.

      Of course, for some reason I think it would be difficult to make Visual Google function that well... the only way I would get results for my Thing would be if someone already knew what it was, and defined it for the search engine.

      Seems to me that just offering a mapping function via cell locators would be more popular.

      Imagine you're a photographer. Professional or hobbyist, I don't care. You have made thousands of pictures; they all are on your hard drive.

      Imagine you're lazy. (Maybe you don't have to imagine that.) You don't want to describe your photos, you don't want to label them. The only metadata associated to your photos is date and time.

      Imagine you're looking for a particular photo. You know where you'va taken it, you know what is on it, you can remember the subject, the color shades, etc. You just can't remember exactly when you took that picture. How do you search for it?

      Well, you quickly make a drawing in which you try to (sort of) replicate colors and shapes. And you let your computer search for "similar" graphics.

      Such software exists already (for quite some time). There's a beta Free software project (GNU licenced) called imgseek [sourceforge.net]. Current version: 0.8.4. I haven't tried it, I don't know how good it is. But this screenshot [sourceforge.net] looks impressive.

      • Very cool, but completely different. You take your picture of the street corner that youw ant identified from a slightly different angle, and all the lines will be wrong. 3d messes with things like that; imgseek gets to work only in 2d. And it even has trouble with that - it only gives you a rough approximation.

        All imgseek does is compare the wavelets - not even remotely applicable to identifying a 3d scene with a non-predetermined 2d image.

        Still, a neat program. :)
      • There are lots of choices, really. I wrote a perl script [kudla.org] (using Image::Magick) about 5 years ago that did the same thing as this, and the awesome GQView [sf.net] image manager has had visual image matching for nearly as long. On the Windows side, I'm pretty sure ThumbsPlus has a feature like that, and I'm surprised they didn't build it into XP since they were supposed to be all digital-photo-friendly.

  • So I am at work in downtown Fort Worth, TX USA.

    I take a photograph of a building that is under construction here and submit it to the "search engine". So what might I be wondering?
    - what street conrner am I at?
    - who owns/is building/will occupy?
    - what materials is it made of?
    - how is it being constructed?

    Same goes for anything. A flower, a person, an object. Without context, search results will be across the board.

    Huh, now that you mention it, same problem with Google today. Just do a seach for "building
  • It seems unlikely we've discovered the algorithm that will compare two scenes and not get fooled by different angles, perspectives, saturation, angle of sun, street lighting on/off, fog, rain, snowcover, traffic changes, etc.... It may be quite a few decades before it's cheaper to use a computer for this than to have a real human being look at the picture and go "hmmm, looks like a Asian scene, those mopeds look Laotian, and that guy has a bag from Taco Bell-- must be the capital!
  • Jeez, everyone's jumping all over this. "Why not read the street signs?" "What about GPS? This is stupid!" So the submitter cited some lame examples. Join the 0.05% percent of slashdotters and RTFA. He cites ideas like taking a picture of a cafe and getting a food review, or taking a picture of a French menu and getting a translation.

    Maybe it could never work, but in principle, this isn't a bad idea.
  • The only technical challenges he discussed were database size/scope and what resolution to use vs. relevant details.

    I was hoping to find out how, exactly, images could be normalized, and the normalize images indexed in a way to avoid O(N) searches.

    Differences in perspective seem to me to be an enormous hurdle, not to mention shadows that change from hour to hour. Nothing about these challenges was even mentioned in the article

    Looks to me like this guy is trolling patent sharks.
  • Didn't IBM have this ability several years ago? I remember seing ads in magazines that let you search for images based on their shape.
  • And what kind of search results do you get back when you sumbit this picture [goatse.cx]
  • Imagine taking a photo of a street corner to find out where you are, or the photo of a city building to see its history.

    Lame. Better yet:

    1. Identify edible as opposed to poisonous plants when hiking.

    2. Identify a part you took off your car during a doomed DIY tune-up session.

    3. Identify a part that was lying on the ground after you closed up the computer case that you just *swear* wasn't there when you started.

    4. Identify the odd substance in the bowl from the back of the fridge...

    5. ID your blind d
  • While this is quite a cool idea, what we really need is an audio search, where as someone could whistle or hum a few bars of that tune that is stuck in their head, and the search results could tell you what it is, where to buy or download it, the lyrics, etc.
  • I don't know how well it was done, but I remember many demonstrations and other interesting presentations from Informix (now owned by IBM) covering this as - IIRC - a blade plugin to their 9.x series Universal Server. You could submit a picture of, say, a wheel and it would figure out what index picture it was matching and then, of course, retrieve other related information. Pretty cool, but I don't know of anyone who came up with a production case for it.

    One of the big goals of this kind of technology w
  • This needs to be hooked up into a service that archives product manuals. Take a picture of your TV/cell phone/microwave/etc. and this service would be able to give you a PDF of your lost manual.

    No more hunting for model numbers (which I've found are not often included somewhere on the actual product).

  • muwahahahaaa

    writing is speech
    pictures are speech (this)
    code is tshirt is music is speech (decss)
    insert numerous other examples (my laziness)

    good luck continuing to legislate speech as property based upon the medium, the inevitability is that they're all communication and increasingly interchangable. i'd start looking for another way to designate what can be proprietary and not NOW.
  • Something pretty similar has already been done here [ox.ac.uk]. They have an impressive online demo to play with.
    It's called Visual Google - You give it a picture, and it returns all the frames in a movie that contain the picture. The clever bit is that it uses a kind of text-retrieval inspired method to do it, so the processing time is essentially zero (just an inverted index lookup, with "visual words")
  • So we can find that special picture with all the curvy bits in the right places.
  • http://shape.cs.princeton.edu/search.html [princeton.edu] allows you to search a database of 3d models by submitting text, 2d [orthagonal] sketch(s), or a 3d [isometric] sketch, or even a 3d model file. Note that at this time these sketches are drawn by the user at search time, but there is nothing to say they can't use a border detection algorithm to accept image input. Also, once you have some results, you can select 'find similar shape'.
  • IconSurf [iconsurf.com] also searches with images. It is a collection of the favicons of lots of sites. You choose whichever you fancy.
  • Washington U has an interesting software project [washington.edu] along similar lines. It can index thousands of pictures, and then recall them based on your crude drawings. Very cool and I think this tech is already appearing in one open source image management tool.
