2D facial expression recognition via 3D reconstruction and feature fusion.
Journal of Visual Communication and Image Representation（2016）
摘要
•This paper proposed a method for facial expression recognition.•In proposed method, facial depth has been added to facial texture for feature extraction.•We demonstrated that adding the facial depth to feature extraction is effective.•The 3DH-LLBP is proposed for feature extraction from facial depth images.•2D facial expression recognition is performed by combination of 2D and 3D features through feature fusion.
