Greetings Economists, Technology Review has this piece on Face Recognition: http://www.technologyreview.com/Infotech/18796/
"Sponsored by the National Institute of Standards and Technology (NIST), the match up of face-recognition algorithms showed that machine recognition of human individuals has improved tenfold since 2002 and a hundredfold since 1995. Indeed, the best face-recognition algorithms now perform more accurately than most humans can manage. Overall, facial-recognition technology is advancing rapidly." thanks, Doyle Saylor
