基于合成的通用头部网格模型的表情合成
针对当前通用脸部网格模型的可操控性和逼真性难以同时兼顾的问题,提出了一种新的通用网格模型合成方法,该方法基于Candide-3模型和从建模软件中导出来的模型进行简化得到的模型进行结合来合成通用头部模型。在此模型的基础上合成出六大基本表情,对输入人脸正面照片使用ASM（active shape model）算法自动提取出特征点,利用特征点和径向基函数来调整合成的通用模型得到特定的表情。实验结果显示,该通用网格模型具有良好的操控性,且能完整表示整个头部结构,还能表达六大基本表情和特定表情。...

| Bibliography: | 51-1196/TP Candide-3 model; simplified model; general head model; expression synthesis Considering the problem that maneuverability and reality based on the current generic facial mesh model can＇t balance,this paper proposed a new method that combined the Candide-3 model with simplified model exported from software to synthesize general head model. The method,firstly based on the model synthesized the six basic facial expressions,then extracted the feature point from the inputted face images using the ASM algorithm automatically and lastly obtained specific expressions through adjusting the synthetic general model using feature points and radial basis function. The experimental results show that the synthetic general head model has good maneuverability and can present the entire head structure and can express the basic expressions and specific expression.
