Easy, indepently of how good is, just trying to fight against Google resources will crush TinEye. Today must be a terrible day for them.

Idee's business model has little to do with TinEye. They're probably not very worried.

The article said the technology is very similar to Google Goggles. From what I could deduce, Goggles uses some kind of local invariant descriptors (like SIFT or SURF), and TinEye uses some kind of global descriptor (maybe something like this: http://www.hackerfactor.com/blog/index.php?/archives/432-Loo... ).

If that is right, Google will be able to retrieve different photos in which the same object appears, whereas TinEye only retrieves the same image, with or without some changes. So, they're quite different beasts.

Can't wait to see if I am right...

Actually, TinEye is pretty good at partial matching.

I compared/contrasted TinEye against Google CBIR for a bunch of images (I use TinEye a lot) and I have to say TinEye looks better than Google CBIR so far. TinEye has less "zero results" and more search results overall, I get the feeling TinEye deals with "Photoshopped images" better somehow.
