Mona Lisa is 2% Angry

A computer vision expert in Amsterdam used software to develop emotion recognition technology.  A person's face is mapped onto a computer which calculates the expression based on facial points like lip curvature, cheek contraction and eyebrow position.  The system is around 85% accurate which is very close to how accurate humans are.  Won’t be long now before Hal doesn’t need to ask Dave how he’s feeling, he’ll just see and judge for himself.

The software detects happiness, disgust, fear, anger, surprise and sadness, but developers don't yet have the technology to detect more subtle emotions.  Researchers have used this technology to show that the Mona Lisa's expression is 83% happy, 9% disgusted, 6% fearful, and 2% angry.

Emotion-recognition technology could have beneficial uses like detecting if a driver is getting sleepy at the wheel and have an alert signal wake them.  But I anticipate it’s more likely to be used to detect how you feel about certain items while you're shopping.

Here's the researchers website where you can submit your own photo.  Or maybe some other persons photo…
