Computer, Read My Lips From: Phys.Org - 09/10/2012 Manipal International University researchers have developed a system that can interpret human emotions based on lip patterns, using a genetic algorithm that can match irregular ellipse fitting equations to the shape of the human mouth displaying different emotions. The researchers say they have trained the computer to recognize happiness, sadness, fear, anger, disgust, and surprise, as well as a neutral expression, by using photos of individuals from Japan and Southeast Asia. The upper and lower lips are analyzed as two separate ellipses by the algorithm. "In recent years, there has been a growing interest in improving all aspects of interaction between humans and computers especially in the area of human emotion recognition by observing facial expression," the researchers note. Initial applications of the system could be in helping disabled patients to interact more effectively with computer-based communication devices, according to the researchers.
