Microsoft Research revealed one of their projects at TechFest 2010 called “OneAlbum,” which’s a project that uses face-recognition and event-matching technology to retrieve automatically photos that would interest you from social networks and your friends’ online photo albums—and add them to yours. OneAlbum automatically finds relevant photos in my friends' albums on social networks or in shared albums, brings them to my album, and shows them side-by-side with the photos I've taken. The technology behind OneAlbum is a novel, unsupervised face-recognition algorithm. It analyzes the photos in my album to find automatically the faces of people I most care about, based on frequency of their appearance; no tagging is required. Then, using the social-network graph and other information, OneAlbum crawls my friend's albums looking for photos of people that interest me. The algorithm was tested on real large-scale albums including tens of thousands of photos and achieved accuracy rates as high as 90 percent.
