Facing the Alternatives: Computers Can Recognize Your Expressions

Recognizing your facial expressions ...

"Spanish researchers have developed software for facial expression recognition, which can identify if the user is happy, sad, surprised or disgusted. When this technology is cooked, how will it be put to use?

Your computer knows you're in a bad mood. Or, at least, that's one possible future. Researchers have developed an algorithm that can recognize a person's facial expressions, and categorize them as anger, disgust, fear, happiness, sadness and surprise.

Researchers at the Department of Artificial Intelligence (DIA) of the Universidad Polit├ęcnica de Madrid's School of Computing (FIUPM) worked with Madrid's Universidad Rey Juan Carlos. The prototype software they developed can process a sequence of moving faces and recognize the person's facial expression. "The software can be applied to video sequences in realistic situations and can identify the facial expression of a person seated in front of a computer screen," according to a university statement.

The software monitors facial movements in several parts of his face, examining up to 30 images per second. The data is compared to expressions captured from 333 sequences of different people from the Cohn-Kanade database, with an 89 percent success rate. "It can work under adverse conditions," according to the statement, "where ambient lighting, frontal facial movements or camera displacements produce major changes in facial appearance." The results of this research were published in the January issue of Pattern Analysis and Applications."    (Continued via CIO)    [Usability Resources]
