Calling the roll with face rec

It doesn't take a Ph.D.  to read the same list of people's names over and over again. So why do we make them do it?

Facial-recognition use grows as accuracy rises, cost declines (China Daily)
Wei Xiaoyong, an associate professor at Sichuan University, used to worry about taking roll call for his class of 100 students.

"It is time-consuming. But students who attend classes every day say it is unfair if I do not do it."

Wei eventually found the solution - a face recognition system.

With the system, all he has to do is to use an ordinary pocket camera to take a picture of the class. Wei then uploads the picture and the computer will automatically find out who showed up for class.

Wei has not noted a single absence since he started using the system.
