Study more than triples the number of facial expressions
researchers can use to track the origins of emotions in the brain
Researchers at The Ohio State University have found a way
for computers to recognize 21 distinct facial expressions—even expressions for
complex or seemingly contradictory emotions such as “happily disgusted” or
“sadly angry.”
In the current issue of the Proceedings of the National
Academy of Sciences, they report that they were able to more than triple the
number of documented facial expressions that researchers can now use for
cognitive analysis.
