Posted: Fri Mar 27, 2009 2:05 pm Post subject: TinEye, a reversed image search engine |
|
|
I just found the coolest thing ever.
I'm not sure if it's useful but it sure is nice and I think it's a great example of advanced image recognition.
It's called TinEye and it's a reversed image search engine.
It is possible to upload an image and TinEye will give you (partly) matching images. That means that if you have a shopped file consisting of a few images you might find the original ones.
They have a page, http://tineye.com/cool_searches which shows some cool examples.
What do you think? _________________ My new site |

That is kind of cool. I've tried some images that were on my computer, and it did find a lot of matches to the default backgrounds that come with Vista... but that was boring.
Then I went to http://worth1000.com (a site that has photo modification competitions and stuff) and played with some of the pictures from there! Much better. It finds the source pictures like a charm. Awesome  _________________ Tarakana NET |

Yeah it works really well, you can also find the source image of some people their avatars with it  _________________ Dilly dally, shilly shally. |

I think this is actually a really cool idea. I took a look at the demonstration video and I noticed Amber Mac was the one introducing the service. I figured there's a good chance the site is Toronto based, and sure enough, Idee is based in Toronto, Canada. It's nice to be able to support home grown companies, especially when they offer some unique services for the world to use.
I think their index is still a little too small for the images that I tried to look up, but based on the example searches I think the site has big potential to go a long way and to be implemented into a variety of different uses.
Thanks for the heads up! _________________ Come visit Shattered Abstracts! (Photoblog!) |

I still think it's quite nice I wonder how they store image data so it's searchable/comparable. _________________ My new site |

Well for text you have several methods. You can calculate the levenshtein distance (pretty intensive though). On the other hand you have Soundex. It generates a small string based on the way the words are pronounced. So my guess is that similar methods exist for images to generate easy to search values that represent images. _________________ Dilly dally, shilly shally. |

According to their site, they create a fingerprint of the image. How this fingerprint is determined is something I am curious about. I know Musicbrainz and Audioscrobbler (Last.fm) do the same thing for music.
All I can guess is that the fingerprint is in some easily comparable format which also allows to match parts of the image. _________________ If you can read this, my post is on an alternating background. |

I'd imagine it would be a blueprint of pixels in a picture. But then my curiosity would be to ask how they handle that between different sized pictures of the same subject matter. _________________ Come visit Shattered Abstracts! (Photoblog!) |

That's pretty interesting. Essentially, for people who are not interested in the entire article, this is the basic idea:
| Quote: | | The wavelet transform is a tool that has emerged from the mathematics community in last decade or so for analyzing functions at different levels of detail. It is similar to the Fourier transform, but encodes both frequency and spacial information. |
Simplifying the detail of the image to a certain level makes it comparable. _________________ If you can read this, my post is on an alternating background. |

I had always hope for such a service, and I do hope Google comes out with their own version (I guess this time someone beat them to it).
For example you could probably grab a picture of George W. Bush, do a TinEye and get parodies of it. _________________

doesn't all google services start out made by someone else, and google gobbles them up? (or googles them up). _________________ For Metal and Rock interviews and reviews, go to www.heavymetalnation.com - You can Contribute too if you want!

I think google tries to beat the competition first and then realizes it can't and googles you up. _________________ http://mydorksite.com |

That's just what rich companies do. If buying a service from someone else is cheaper than developing it yourself, then just buy it when possible. _________________ If you can read this, my post is on an alternating background. |
