| Abstract: | A facial expression recognition method based on 3D landmark model matching is proposed. Firstly, facial landmarks are extracted based on a mixtures-of-trees structured model, and then a facial landmark model is built. Then Generalized Procrustes Analysis is used to do the model alignment in order to get the robust matching features. Finally, facial expression recognition is accomplished by SVM classification. Experiments are conducted on BU-3DFE dataset with six different facial expressions. The result shows that the algorithm has good performance on facial expression recognition. |
