Analysis and synthesis of facial expression using high-definition wire frame model

We propose the method to extract facial expression parameter with quantitative analysis of 9-dimensional movement of facial surface that arises from real human expression, using high-definition model. By dividing the face surface to some regions having similar characteristics of movement and modeling with 3-dimensional round surface in each region respectively, we can derive the muscle control parameters and the rule of movement. Considering the findings of this analysis we propose also a synthesis method of real facial expression image based on this high-definition model
