The system still needs improvement, but it could be useful for extracting number data from billions of images, the researchers say. Ultimately, this could make Street View a lot more accurate. Without a house-number-based view, an address in Street View is a default panorama, which might not actually be the address you want. Type in "30 Rockefeller Plaza," for instance, and the first thing you see is a chocolatier next to the 30 Rock observation deck. You have to click and drag to see the NBC building.
