Abstract: Aiming at the problems existing in facial expression recognition currently, based on the data in the 3D expression database BU-3DFE, we study the point cloud alignment of 3D facial expression data, establish the bilinear models based on the alignment data, and improve the recognition algorithms based on bilinear model in order to form the new recognition and classification algorithms, to reduce the quantity of identity feature calculation in original algorithm, to minimize the influence of identity feature on the total expression recognition process, to improve the results of facial expression recognition, and to ultimately achieve the high robustness of 3D facial expression recognition.

Key words: facial expression recognition, feature extraction, bilinear model, TPS alignment
