Japanese technology can measure your smile… cheer up!
Possibly a predecessor of the computer which can measure attractiveness, new Japanese technology is able to measure someone’s smile on a scale of nought to 100.
Firstly, video images are scanned to detect faces, and then the computer analyses the curves of the lips, eye movement, and other facial characteristics, to decide how much a person is smiling.
It can analyse up to one hundred faces simultaneously.
Though Sony has already developed technology for its cameras, which automatically takes a photo when people in the shot are smiling, the developers say that their technology could be used in medical applications, to assess the emotional state of patients, for people who wish to perfect their smile, or for enabling robots to decipher human reactions.
