The Swiss Kooaba just keeps on innovating. In January Kooaba was behind the first daily newspaper that was fully augmented. Now it is the first (as far as I can tell) that offers a public, free (though limited) to their image recognition capabilities.
Using the api, one can send up to 50 daily image queries to Kooaba's servers that cover "close to ten million" movie poster, books and cd covers. They were even nice enough to provide sample code in several programming languages to get you started writing your own application. So basically, you can make your own SnapTell (or a simple Google Goggles clone).
You can find more details about it over at Kooaba's blog. It's an interesting move, but I fear that in the long run it won't suffice to fend off Google. Google has the largest image database, and I would like to see Kooaba open up their "image uploading api" (the one that lets you enter new images to the database) in order to compete with them.
