An efficient multimodal 2D + 3D feature-based approach to automatic facial expression recognition
We propose a feature-based 2D+3D multimodal facial expression recognition method. It is fully automatic benefit from a large set of automatically detected landmarks. The complementarities between 2D and 3D features are comprehensively demonstrated. Our method achieves the best accuracy on the BU3DFE database so far. A good generalization ability is shown on the Bosphorus database.
