中文摘要：

提出的细分曲面水印算法是基于图像水印算法和Fourier加法性质。首先将水印信息嵌入一幅图像，通过嵌入水印的图像和原始图像在空域作比较得到含有水印信息的矩阵，然后将细分曲面初始网格迭代三次以使网格的顶点数足够多，最后取出一部分顶点坐标和含有水印信息的矩阵相加得到嵌入水印的网格，嵌入水印后的网格作为新的初始网格。实验结果证明该算法具有较好的强壮性和计算量小的特点。

英文摘要：

The subdivision surface is obtained based on one image watermarking algorithm and the addition property of Fourier transform. First, the watermark noise is obtained by the image algorithm. Secondly, some vertex coordinates are obtained after the original mesh is subdivided three times. Finally, the watermark noise is added to the vertex coordinates to produce the watermarked mesh. The experiments show that it is transparent, robust, accurate and cost-efficient.
