MPEG-4将于1999年3月成为国际标准。本文介绍了一种与MPEG-4标准人脸对象规范兼容的虚拟克隆方法和动画系统的实验。我们的方法使用正交的照片（正面和侧面）作为输入，并重建三维人脸模型。该方法基于从照片中提取MPEG-4人脸定义参数（FDP），该参数在更强大的界面中显示自定义人脸，并使通用模型变形。纹理映射使用由两个正交图像组成的图像，这是完全自动完成的。一个重建的头部可以立即在我们的动画系统，这是适应MPEG-4标准规范的面部动画参数（FAP）内的动画。结果被集成到我们的虚拟人导演（VHD）系统。
MPEG-4 is scheduled to become an international standard in March 1999. The paper demonstrates an experiment for a virtual cloning method and animation system, which is compatible with the MPEG-4 standard facial object specification. Our method uses orthogonal photos (front and side view) as input and reconstructs the 3D facial model. The method is based on extracting MPEG-4 face definition parameters (FDP) from photos, which initializes a custom face in a more capable interface, and deforming a generic model. Texture mapping is employed using an image composed of the two orthogonal images, which is done completely automatically. A reconstructed head can be animated immediately inside our animation system, which is adapted to the MPEG-4 standard specification of face animation parameters (FAP). The result is integrated into our virtual human director (VHD) system.
