image recognition on mobile phones is becoming a must have feature.
An example with Amazon App.

I took a picture of a sea turtle,

the Amazon app sends the picture to the server and an email is sent when the results are ready:

And the result was pretty good:

I have been trying a few interesting mobile apps.

Google shopper, Shopper lets you find product information quickly by using your phone’s camera. It can recognize cover art of books, CDs, DVDs, and video games, along with most barcodes. You can also speak the name of the product you’re looking for. Use Shopper to make smart decisions about what to buy, what price to pay, and where to buy it. You can star items for later and share them with friends. Shopper also saves your history so you’ll always have product and price information at your fingertips, even when you don’t have a signal.

Google Goggles, showcases the potential of integrating Google’s machine translation and image recognition technologies.

Amazon App , ShopSavvy users can scan the barcode of any product using their phone’s built-in camera. Once scanned, it will search for all the best prices on the internet and locally. Mobile barcodes readers go mainstream, these application show what’s next.

The interesting thing is that these applications work pretty well already. Mobile phones are become more and more smarter.
