具有真实感的虚拟人脸合成

Synthesis of a realistic virtual 3-D human face

建立了一个可变形的三维人脸网格模型,通过两种变形方法使网格模型与特定人脸照片相匹配;利用所提供的特定人脸的照片,合成人脸的无缝拼接纹理图,同时对变形后的特定人脸网格模型进行了Bezier磨光;将人脸无缝拼接纹理图映射到Bezier磨光后的特定人脸网格模型上,从而生成具有真实感的三维人脸.

Synthesis of a realistic virtual 3-D human face using a computer has become a research 'hot' subject in the computer graphics field. First, a deformable 3-D face mesh model is constructed, which is edited interactively to match the specific face photographys by the two morphing methods, i.e., coarse morphing technology and careful morphing technology. In order to display the specific humane face realistically, a texture image is synthesized from the specific face photographs and a careful mesh model is generated after Bezier smoothing is used. And the synthetic texture image is mapped onto the smoothed mesh model so that a realistic virtual 3-D humane face model is generated.
