The study the ability of humans to read subtle change sin facial expressions, theist they applied reverse correlation technique to reveal visual features that mediate understanding of emotion expressed by the face. Surprising finding were that (1) the noise added to test face image had profound effect on the facial expression and (2) in almost every distance the new expression was meaningful.

All 44 major muscles in the mode must move like human muscles. Movement of one or more muscles is called an "action unit" Then Dr. Paul ECAM, creator of (FACS) Human has classified six basic emotions- happiness, surprise, anger, disgust, feat and sadness. In the text it states,"The soft wear is the latest innovation from Prof. Thomas Huang, of the Beckman Institute for Advance Science at the University of

Illinois." Dr. Hung and colleague are experts at developing better ways for humans and computers to communicate. The facial expressions for each emotion are universal, observers Dr. Huang, even thought individuals often show varying degrees of expression (like smiling broadly). Using video imagery, the new emotion-recqizing software facture these movements.

The study the ability of humans to read subtle change sin facial expressions, theist they applied reverse correlation technique to reveal visual features that mediate understanding of emotion expressed by the face. The process begins whine the computer constructs a 3-D computer Model.

The study the ability of humans to read subtle change sin facial expressions, theist they applied reverse correlation technique to reveal visual features that mediate understanding of emotion expressed by the face. Facial expression not only expresses emotions but also even help reproduce them. The thought of making faces could reveal so much about the science of emotions.
