Facial expression recognition software developed

Researchers at the Department of Artificial Intelligence (DIA) of Universidad Politécnica de Madrid have developed an algorithm that is capable of detecting a person’s facial expressions. The software can analyze 30 images per second and categorize expressions as anger, disgust, fear, happiness, sadness, or surprise.

The software is capable of following a face around and spot its emotions anywhere in a frame. It can even work on recorded video, recognizing what expressions a face in the video is showing.

Although only a prototype, the software is capable of working on a regular desktop or laptop computer, allowing you to take it with you and use a webcam to analyze your expressions (in case you don’t know how you’re feeling at any given time).

This software has great potential for a wide variety of uses. For example, it might eventually be used as a sort of detector to see if a person is lying.
