There are supposedly several telltale signs that someone is faking a smile, such as the lack of wrinkles around the eyes. Yet spotting one in the heat of the moment is somewhat easier said than done. A new study from the University of Bradford set out to see if AI could do a better job.
The software developed by the team analyzed a range of photos and videos to spot the movement of the smile across each person’s face in order to detect whether it was genuine or not. As the experts suggest, the software thought the most significant movements were around the eyes.
