This paper studies facial beauty analysis by using feature-based computer models in prediction and beautification. In order to assess the facial beauty index, a facial beauty prediction model is established, which can quickly and effectively estimate beauty indexes for new images. In the facial beautification model, we mainly achieve three functions: (1) propose an effective method to adjust the positions of the landmark points to beautify the facial geometry; (2) improve the multi-level median filtering method to perform facial skin beautification; and (3) design a method to achieve average facial beautification. Experimental results showed that the proposed models can significantly analyze the facial attractiveness of face images.
