FRVT 2006/ICE 2006: Computers outperform humans at recognizing faces

The best face-recognition algorithms now perform more accurately than most humans can manage. According to the recent Face Recognition Grand Challenge, The match up of face-recognition algorithms showed that machine recognition of human individuals has improved tenfold since 2002 and a hundredfold since 1995.

For the FRVT 2006 and the ICE 2006, sets of high-resolution face images, 3-D face scans, and iris images were collected of the same people, Phillips says. The FRVT 2006 for the first time measured the performance of six 3-D algorithms on a set of 3-D face scans. The ICE 2006 measured the performance of ten algorithms on a set of iris images. 3-D face recognition has come into its own in the last few years because 3-D sensors for face recognition have become available only recently. What 3-D face recognition contributes is that it directly captures information about the shapes of faces.

UMICH: High-testosterone people reinforced by others' anger

Most people don't appreciate an angry look, but a new University of Michigan psychology study found that some people find angry expressions so rewarding that they will readily learn ways to encourage them. "It's kind of striking that an angry facial expression is consciously valued as a very negative signal by almost everyone, yet at a non-conscious level can be like a tasty morsel that some people will vigorously work for," said Oliver Schultheiss, co-author of the study and a U-M associate professor of psychology.

The findings may explain why some people like to tease each other so much, he added. "Perhaps teasers are reinforced by that fleeting 'annoyed look' on someone else's face and therefore will continue to heckle that person to get that look again and again," he said. "As long as it does not stay there for long, it's not perceived as a threat, but as a reward."
