Rice University computer scientists have created a new system for mobile users to quickly determine their location indoors without communicating with the cloud, networks or other devices. The battery-saving scheme uses image recognition and "hashing," a method that reduces key details in a photo to short strings of numbers called hashes. To determine a location, the system hashes a photo from the user's camera and compares it against a pre-downloaded, highly compressed location database called a hash table.
