交互式进化计算在虚拟角色表情建模中的应用

阐述了一种将交互式进化计算应用于三维计算机动画影片中训练虚拟角色面部表情的方法。将模糊神经网络应用于虚拟角色面部表情的建模，并用遗传算法结合交互式进化计算训练模糊神经网络。实验结果表明，当该算法应用于训练虚拟角色面部表情这一问题时,能在保证精度的前提下快速收敛，并能避免陷入局部最优，从而使得不同的动画导演利用这个系统,能够生成符合自己要求的虚拟面部表情。

Application of interactive evolutionary computation in virtual actor's expression modeling

An Interactive Evolutionary Computation (IEC) method was illustrated for training the facial expressions of the virtual actors in three dimensional computer graphical movies according to the effect that the human directors expect. Fuzzy neural network was used to accommodate director's expert knowledge so that appropriate virtual actor's facial expression could be produced. In order to speed up the convergence of the learning algorithm, genetic algorithm was incorporated into the fuzzy neural network with IEC. Experimental results indicate the success of our approach here.
