The Computer Program that knows how you feel

A new facial analysis software has been developed that claims to be able to recognize a person's mood in an instant.This could mean the start of personalized advertising campaigns that can tell how you feel by simply looking at your face.
The 'rapid facial analysis' technology is being developed by researchers at the German Fraunhofer Institute (GFI).It uses highly complex software to find a human face in an image,work out whether the face is male or female,and then analyze their expressions.The most important facial characteristics used by the system are the contours of the face,the eyes, the eyebrows and the nose.The system first has to go through a training phase in which it is presented with huge quantities of data containing images of faces.The computer compares 30000 facial characteristics with the information that it has previously learned.
The system can be used to check the levels of concentration of car drivers.
