基于面分块的人脸造型技术研究

Research on Human Face Modeling Based on Face Subdivision

人脸面部是一个极其复杂的曲面 ,若将其作为一个整体进行人脸造型则使问题复杂化 .本项研究在总结前人研究工作的基础上 ,提出了一种将人脸面部分为若干块、分别进行处理的人脸造型方法 ,同时将人脸表面形变模拟成弹性体的形变 ,并为其建立了弹性形变模型 ,实现了从一般人脸模型到特定人脸模型的造型 ,算法效率高、交互操作少 ,结果令人满意 .

Human face is a complicated curved surface. It may be more difficult to take a human face as a whole during face modeling. So we put forward a new method by which the surface of a human face is divided into some parts and every part is individually manipulated. At the same time, we take the human face as a elastomer and set up metamorphosable model for them. By this method we create a system in which a specific face model can be generated. And the algorithm used in this system is characterized by higher efficiency and less interactive operations. Some satisfactory results from the system are given.
