TinEye and Google Goggles applied to the entire Internet? Yes please. I can't wait to play around with this. What will be even more interesting is if they release an API for it in the future. Sites like imgur and reddit could then suggest if you're uploading or submitting a similar image to one that already exists.

I just tried TinEye (hadn't heard of it before) and it appears to only look for images that are modifications of the image being searched for. I wonder if Google's will work the same, or if it will be possible to find other images that are similar, but not based on the same image? That's what I really want.

Here's an interesting article about image hashing and fingerprinting algorithms: http://www.hackerfactor.com/blog/index.php?/archives/432-Loo...

Everything from that blog is interesting, do you or anyone else got any suggestions for similar blogs?

The "similarity" of two images is a very complicated concept, when people are asked to tag images the overlap rarely goes above 20% on average (e.g. check out http://images.google.com/imagelabeler/ and try your hand at it). Think about it: you may think at the object level (both images have cars), concept level (both are happy images), color, etc. This is why large online stock image sellers still rely on tags extensively.

As a rough analogy, consider a textual example: Find a sentence similar to "It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife." Now, if you enter this sentence in Google, it retrieves documents that contain it, in TinyEye fashion. What other similarity is desired? Should it retrieve essays on Austen, on marriage, 17th century English literature...?

If you are interested in image similarity search, check out the Pascal challenge (http://pascallin.ecs.soton.ac.uk/challenges/VOC/voc2011/inde...). The advances in the last 5-6 years on object detection and visual feature extraction (which image similarity relies on) is amazing.

I use TinEye a lot and I think this will be great. My typical uses of TinEye, that will probably be improved with the bigger stock:

- somebody put text over a nice image and I want the unmodified version

- searching for bigger, better quality versions of an image (e.g. wallpapers)

- finding other images from the same author/gallery (since it links to the sites that hosts the copies)

- finding the name of the movie, person or object pictured (because copies will be hosted with different, probably meaningful names and in pages with subtitles)

From my understanding, TinEye makes money from corporate B2B deals. Their consumer product is mostly just a technology demo/marketing piece rather than a part of their core business.

So they probably don't have much to worry about.
