Toronto, Oct 2 (IANS) An Indian-origin computer
scientist at Concordia University in Montreal 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.
``If one could
take random photos of the crowd and process them fast enough, there is
the potential to identify those individuals who might be problematic,''
the statement said.
While detecting facial expressions, the system will focus on muscles under the face near the eyes, nose and mouth.
``Bhattacharya
and Sohail's system measures 15 key points on the face and then
compares these measures against images of identifiable facial
expressions,'' the statement said.
Even though individuals and
cultures vary in facial expressions in myriad ways, Bhattacharya and
Sohail have identified seven basic facial expressions which all humans
share.
These seven universal expressions will help the computer
imaging process to classify them and then know whether that individual
posed any threat.
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.
