Abstract:

In facial expression recognition system, due to the differences of faces,the complexity of organ distribution and the influence of outside factors,facial features location becomes a challenging task.Using Kinect point distribution,we present a feature extraction algorithm for facial expressions,and carry out related experiments.Experimental results show that the proposed method has significant advantages in extracting features that are with unrelated deformation,nonsensitive to noise,or have a high degree of distinction.
