HUMAN-MACHINE INTERACTION IN FACIAL EXPRESSION RECOGNITION SYSTEM

Image processing is an image-in and image-out work, in that artificial intelligence in affective computing is scientifically challenged Research area in the field of computer vision technology. Facial expressions are the fundamental way to express human emotions and also an effective method of non-verbal communication, development of artificial intelligence and pattern recognition, researchers paying more and more attention to the facial expression recognition system. The Human can easily recognize facial expression, but it is quite a challenging task for the machine to do this many application which use facial expression to evaluate the human nature, feelings, judgment and opinion. This paper presents a broad review of various modules in the facial expression recognition system and robust techniques used at each level. An ongoing challenge in this field is to design an intelligence system for effective human-machine interactions.
