Abstract :
In this paper we present our framework for facial expression analysis using static models and kernel methods for classification. We describe the characterization methodology from parametric model. Also quantitatively evaluated the accuracy for feature detection and estimation of the parameters associated with facial expressions, analyzing its robustness to variations in pose. Then, a methodology of emotion characterization is introduced to perform the recognition. Furthermore, a cascade classifiers using kernel methods it is performed for emotion recognition. The experimental results show that the proposed model can effectively detect the different facial expressions. The model used and characterization methodology showed efficient to detect the emotion type in 93.4% of the cases.
