So does the sure-handed urgency with which he rhythmically taps out commands on his keyboard.
Within an instant the man's face, so barely distinguishable from the static, snowy image on the screen, begins to churn. Underneath, algorithms developed inside Savvides' biometrics lab at Carnegie Mellon University's Electrical and Computer Engineering Department whirr and whizz. Soon the outcome is there: A three-dimensional model of the subject's face that rotates at the whim of a mouse click. The animated model is a golden image, one that can be compared, for example, to images of known terrorists stored in a database.
