中文摘要：

人脸图像变形技术是人脸动画制作过程中最关键的技术之一，文章研究了基于Laplacian优化变形算法，首先制定一个局部缺陷模型，通过改变模型结构和纹理的参数，使其与其它部位一样，然后将修改后的缺陷部位拼接目标颜面来恢复变形．实验表明，该方法相对于其它变形方法可以高精度恢复人脸图像．

英文摘要：

Facial image deformation technology is one of the most important technologies in the process of human face animation. In this paper, we study the optimization algorithm based on Laplacian. Firstly, a local defect model is developed. And then the model structure and texture parameters are changed to make it as same as the other parts of the face. Finally, defect model will be spliced to the target face for restoring the deformation. Experiments show that the method can restore the facial image with high precision compared with other deformation methods.
