Computer imaging to read human faces to detect threat

An computer scientist at Concordia University in Montreal, Canada is developing a computer imaging process that will read expressions on a human face to know that person's motives and intentions.

The system will classify these expressions to let analysts know whether that individual posed any public threat. A university statement said Prof Prabir Bhattacharya and his graduate student Abu Sayeed Sohail were on the verge of developing this computer image processing system for detecting and classifying human facial expressions.

It said this system will help take and analyse photos of individuals, potentially in areas of high traffic where security is a primary concern, such as an airport.

While detecting facial expressions, the system will focus on muscles under the face near the eyes, nose and mouth.

The results of their yet-to-be concluded research have been published as Classification of Human Facial Expression: A Prospective Application of Image Processing and Machine Learning.
