Abstract
We have developed a real-time system for expressing emotion as a portrait
selected according to the facial expression while writing a message. The
portrait is decided by a hair style, a facial outline, and a cartoon of
facial expression. The image signal is analyzed by the system using image
processing software (OpenCV). The system selects one portrait expressing
one of neutral, subtly smiling and smiling facial expressions using two
thresholds on facial expression intensity. We applied the system to post
on a Social Network Service (SNS) a message and a portrait expressing the
facial expression.
