[show abstract][hide abstract] ABSTRACT: The validity of PAD (Pleasure-Arousal-Dominance) theory in vision area and the feasibilityT on PAD based models for facial
expression analysis are discussed in this paper. Three new models based on PAD theory are proposed and their feasibility is
verified by experiments on Cohn-Kanade dataset and PAD dataset which is collected from well-designed psychological experiments.
After combining Gabor feature and SVM (Support Vector Machine), the result can be further improved. Compared with the basic
expression models, our experiments show that the predominance of PAD based model is that it can represent almost any states
of expression. Finally, our preliminary experiments show that distinguishing different grades of the same expression is promising
by our models.
