First, the watermarked image minus the original image is the watermark information. according to the addition property of the fourier transform, a change of spatial domain will cause a change in the frequency domain, which will allow watermarks to be extracted from the watermark information. then, the watermark information is scaled down and embedded in one part of the x - coordinate of the original mesh

    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。
