An Effective Non-blind Watermarking Subdivision Surface Algorithm
一种有效的细分曲面非盲水印算法*

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.
