You can usually recognize a friend even if he changes his facial expression, dons a hat and dark glasses, or grows a beard. Teaching machines to be equally discerning might help thwart terrorists and criminals and clarify how our brains perform the feat. The Face Recognition Homepage from computer scientist Mislav Grgic of the University of Zagreb in Croatia and colleague Kresimir Delac is a hub for researchers in the field. You'll find links to more than 20 databases that hold facial photos for testing machine perception. The site also gathers PDFs of papers that describe face-recognition algorithms and highlights new and classic articles. Other resources include a roster of companies working on identification systems and a calendar of upcoming conferences.
