提出了三維網格模型盲水印演算法：利用fourier加法性質將水印間接嵌入網格模型頂點坐標上，即先將水印嵌入一個穩定圖像中，然後將嵌入水印后的圖像和原始圖像進行比較得到水印信息，最後將水印信息嵌入網格模型頂點坐標上得到嵌入水印的三維網格模型。The embedding template in algorithm allows identifying both the transformation parameters and translation coordinates, so that can estimate distortions and maximize watermark recovery effectiveness
演算法中的嵌入模板既可以標識變換的參數，也可以標識移動的坐標，以便於評估幾何失真程度和提高水印恢復的效率。6 ruanaidh j, pun t. rotation, scale, and translation invariant digital image watermarking. signal processing, 1998, 66 : 303 - 317. 7 lin c, wu m, bloom j, cox i, miller m, lui y. rotation, scale, and translation resilient watermarking for images
本文提出了一種數字圖像水印中的新技術，其特點是：在圖像數字水印的檢測中具有較強的識別能力避免了計算逆的對數極坐標仿射ilpm ，保證了嵌入數字水印后圖像的質量同時也避免了窮舉的搜索，減少了計算時間和誤檢率。分享友人
