Morphable model with shape-constrained 3D face components
形状约束的三维人脸组件形变模型

Traditional 3D face morphable model constructs the space of the shape parameters and texture parameters by studying those from lots of 3D face samples. But the model can not describe the whole morphable space and can not reconstruct 3D shape well from 2D face image. To solve the problem, a face was constructed by some components, such as eyes, mouth, etc. By this method, the morphable model can construct the parameters space better. But, this kind of component model has more parameters and the overlaps between those components are difficult to deal with. In this paper, we used the shape model as a whole and the texture model as components. In this way, we can get a balance between performance and complication.
