Today, my album refers to a collection of photos I have taken. But many photos relevant to me -- such as photos of me or my children—are in my friends' albums. 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. For example, if I was at a party, I'll see all photos from that party—those I've taken and those my friends took. 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.
