Google's foray into Image Search

Google has recently started Google Goggles which can translate text captured in photos. Google uses image recognition technology and helps in searching images. So it'll be very beneficial to mobile users as they can click pictures and get relevant information about the objects.

Two important observations:
1. This image search does not use tagging. So it's a completely new technology where images are being matched from a different database of images.

2. This is an example where different technologies are converging. It's a beautiful combination of Digital Signal Processing and Databases.
