Abstract

Facial expressions are an important channel of nonverbal communication. Currently, many facial expression analysis or recognition systems have been proposed. In this paper, a study of dimension reduction of Gabor features from different facial expressions is presented. Principle Component Analysis (PCA) is used as dimension reduction method. The experiment is conducted by using samples of face image for eight subjects. There are six facial expressions; anger, fear, happy, neutral, sadness and surprise are used in this study. In this experiment, we use different poses and head postures of each subject. Experiment results demonstrated the reduced dimensions of Gabor features could be effectively used in the next processing for recognizing facial expressions.
