Machine Vision Algorithm

"Machine Vision Algorithm Learns to Recognize Hidden Facial Expressions." Emerging Technology From the arXiv. MIT Technology Review on line, 13 November 2015.

Subhead reads, "Microexpressions reveal your deepest emotions, even when you are trying to hide them. Now a machine vision algorithm has learned to spot them, with wide-ranging applications from law enforcement to psychological analysis."

That such microexpressions exist and can be reliably read has served as the premise of the television show Lie to Me, and for research into the question, "Could machines [...] become better at recognizing microexpressions than humans?" The article asserts we can "get an answer" to that question "thanks to the work of Xiaobai Li at the University of Oulu in Finland" and associates, who "have built and tested the first machine vision system capable of spotting and recognizing microexpressions; the researchers assert that as of 2015 their system "is already better than humans at the task."
