Although talk of facial recognition has been aimed at finding people guilty of alleged crimes or recognizing individuals for industry-related purposes, a new use has been found for this technology: identifying drunk people.
A paper published in the International Journal of Electronic Security and Digital Forensics discusses a new infrared-camera algorithm developed at the University of Patras in Greece. It focuses on the heat dispersion on the faces of people in a crowd, paying attention to where blood vessels dilate at the skin’s surface. Drunk individuals tend to have more heat on their noses and less on their foreheads, information that could be beneficial to law enforcement officers in the field who are trying to detect from afar whether or not someone is under the influence of alcohol.
