Computer Perception of Emotion in the Face and Voice

Jeffrey Cohn
Associate Professor of Psychology, University of Pittsburgh
Adjunct Faculty, Robotics Institute, Carnegie Mellon University

Place and Time
Adamson Wing, Baker Hall
Refreshments 3:15 pm
Talk 3:30 pm

Until recently, computer perception of human activity was limited to serial input devices. That is now changing. Recent work in computer vision focuses on the development of computer systems that can detect human activity and recognize the participants. The next step is computer systems that can understand the meaning of human activity. In interdisciplinary collaborations with vision and speech scientists, my colleagues and I have developed prototype computer systems that recognize subtle changes in facial expression and discriminate emotion and communicative intent in face and voice. In part one, I will review Automated Face Analysis, which is a computer-vision based approach to recognizing fine-grained changes in facial expression. In part two, I will review our work in discriminating communicative intention and felt emotion from analyses of vocal fundamental frequency.

Speaker Biography
Dr. Jeffrey Cohn is Associate Professor of Psychology and Psychiatry at the University of Pittsburgh and Adjunct Faculty at the Robotics Institute, Carnegie Mellon University. He earned his PhD in clinical psychology in 1983 from the University of Massachusetts, Amherst. His research focuses on emotion processes and their relation to the development of affective disorders in children and adults. To make feasible more rigorous, quantitative measurement of emotion expression, he formed two interdisciplinary research groups with expertise in computer vision, speech science, and human emotion and nonverbal communication. His work on these topics has been supported by grants from the National Science Foundation and the National Institute of Mental Health.
