Detecting human face and recognizing facial expressions using potential net
Hiroaki Bessho, Yoshio Iwai, M. Yachida · 2002
The paper deals with the detection of human faces in an image and recognition of their facial expressions using the potential net. Previously, we proposed a method to recognize facial expression using the potential net and KL expansion. In this method, it was necessary to assign a face area manually. This manual process will affect the application of recognition of facial expression to man-machine interaction. In this paper, we propose a method to automatically detect human faces by pattern matching using the potential net and to recognize facial expressions of the detected face area.
