text: In the artical it shows that this software could recognize the subtle emotions made by the Leonardo da Vinici's painting of Mona Lisa. FACS can recognize the facial expressions made by a child or teenager and recognize the six (happiness, surprise, anger, discust,fear and sadness) basic emotions, just like us people do in our everyday lives. The software can also recognize mixed emotions; FACS has found that the Mona Lisa is displaying 83 percent happiness, 9 percent discust, 6 percent fear, and 2 percent of anger.
