• 灰度水印 - 引用次数：4

  The gray-level watermark image is decomposed with blocked-DCT transform after being Arnold scrambled. Then DCT coefficients are classified and inserted into SVD of original image with different strength.

  该算法将原始图像的小波子图进行奇异值分解,将灰度水印图像进行Arnold变换以及扰乱加密,再进行分块离散余弦变换(Discrete Cosine Transform,DCT),将变换后的系数分类嵌入到相应的奇异值中。
