Design and implementation of human face cartoon animation system combining face expressions and deformation technology

针对实时生成人脸卡通动画的需求,设计和实现一种结合人脸表情与变形技术的人脸卡通动画系统。该系统包括人脸检测、特征点定位、人脸表情生成和人脸变形4个部分,首先,使用Haar特征和级联AdaBoost分类器检测人脸,并使用主动形状模型定位人脸特征点;然后,根据人脸特征和已有的卡通素材器官合成与真实人脸所对应的卡通人脸,并合成动态表情;最后,使用图像变形技术对人脸进行夸张变形处理,生成具有幽默、夸张效果的人脸图像。基于Matlab的实现效果表明,该系统能实时、高效地处理真实人脸图像。

In allusion to the real-time generation demand of human face cartoon animation,a human face cartoon animation system combining face expressions and deformation technology is designed and implemented. The system includes four parts of face detection,feature point location,face expression generation,and face deformation. The Haar feature and concatenated Ada Boost classifier are used to detect faces,and the active shape model is used to locate face feature points. The cartoon face corresponding to the real face is synthesized according to the face features and the existing cartoon material organs,and the dynamic expressions are synthesized. The image deformation technology is used to exaggerate and distort faces to generate humorous and exaggerated face images. The realization effect based on Matlab shows that the system can process real face images in real time and with high efficiency.
