It is an interesting and challenging problem to synthesise vivid facial expression images. In this paper, we propose a facial expression synthesis system which imitates a reference facial expression image according to the difference between shape feature vectors of the neutral image and expression image. To improve the result, two stages of postprocessing are involved. We focus on the facial expressions of happiness, sadness, and surprise. Experimental results show vivid and flexible results.
