Program Pinpoints Locations of Photos

Graduate Ph.D student James Hays has developed a computer program that can estimate the geographic location of photos. The program analyzes the composition of the photo, as opposed to language on street signs or landmarks. The computer then searches a database of photos that have a GPS coordinate attached to them, and narrows down the possibility of where the picture is located. The program operates at 16% efficiency, which is three times greater than what Hays had anticipated.
