用卷积曲面生成脸部皱纹的方法

将卷积曲面应用于人脸建模，提出了在个性化人脸模型上生成皱纹的新方法。运用基于图像的建模方法将通用人脸网格变形并计算出纹理图像，变形后的网格再与一个核函数卷积生成卷积曲面，通过轮廓函数调整曲面的形状而产生皱纹。将纹理图像映射到卷积曲面上使皱纹具有真实感。实验结果表明本文的方法可以通过控制轮廓函数的参数生成不同外观的皱纹。

Facial wrinkle simulation using convolution surface

A new method to simulate wrinkles on individual face model was presented, which applied convolution surface to face modeling. A generic face mesh was deformed and the texture image was computed using image-based modeling technique. The deformed mesh was then convolved with a kernel function to generate a convolution surface, and wrinkles were generated by modulating the surface with a designed profile function. The pre-computed texture was mapped onto the convolution surface to enhance the realism. Experimental results show that our method can generate wrinkles with different patterns by regulating some parameters of the profile function.
