Computer Perception of Emotion in the Face and Voice
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
Abstract
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.
