Abstract: In order to present the result of facial plastic surgery accurately, we propose a mesh morphing process method based on the grayscale texture in this paper. A grayscale texture is created by selecting the region of interest (ROI), and a set of texture coordinate is computed for the vertices in real time to establish the mapping relationship between the vertices and the grayscale texture. In order to make the morphing smooth, we blur the grayscale texture with the mean blurred processing algorithm and control the blur effect by the number of iterations. The advantages of this algorithm are as follows: The morphing information of the mesh is stored in the grayscale texture, so that the morphing information and the model's geometric information are independent of each other; Direct operation of grid vertices can control the morphing effect of the mesh accurately; There is no need to preprocess the 3D model.

Key words: mesh morphing, grayscale texture, blurred processing, plastic surgery
