Based on the two face images of the same person at front and half-profile view and an MPEG4 3D generic face model, we estimate the poses of the face at these two images and establish their 2D mesh models. Multiple views of the same face can be synthesized by image interpolation and warping, meanwhile occlusion problems are solved reasonably.

基于同一人脸的正面和半侧面图像，引入三维通用人脸模型估计其初始朝向，分别建立两图像的二维网格模型；然后采用图像插值和变形技术合成不同朝向人脸，并合理地解决遮挡问题。

The quality of purified 2-KGA from its fermentation products was up to industrial standard. In addition, several hexoses, such as D-glucose and D-sorbitol can be utilized to synthesize 2-KGA by this newly-mixed culture. The growth and anabolism of the B529-V6 were studied in 4M〓 and 300M〓 fermentor respectively. The results showed that its growth and anabolism were affected by carbon sources, ratio of D-glucose and L-sorbose, nitrogen sources, growth factors, inoculum quality and culture condition including the initial pH value, temperature and ventilation.
