Looking For Someone? Search The World’s Smartphone Photos.

“Researchers have devised and tested a system that can search mobile phones in realtime in an efficient way to find targets in crowd-sourced images.

Ardalan Amiri Sani and co-workers at Rice University in Texas describe in a recent paper a new system called Theia that can search mobile phones in an efficient way for target images.

All you have to do is download an app that connects to a server. A user of the service submits a query and the phone app performs a search on the photo’s met data and the photo itself. For example you could specify a particular face and a particular background. To avoid overloading the phone the search is a two-stage operation.

First a set of local predicates are derived from the query. These are simpler matching criteria that can be used to quickly select likely candidates for second stage of the search. If a photo is not rejected by the local predicates then it is uploaded to the Theia server and fully analyzed.”
