Facial wrinkle simulation using convolution surface
用卷积曲面生成脸部皱纹的方法

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.
