Description: 将水印图像二值化后，进行n次Arnold变换置换，使能量均匀分布在水印图像的整个空间。然后，根据载体图像的特征，分解出彩色图像的亮度分量，再将置乱后的水印图像嵌入其低频位置。对检测出的信息进行n次反Arnold置乱后，就可以提取出水印图像-After the watermark image binarization, Arnold transform n times replacement, the energy evenly distributed throughout the space watermarked image. Then, according to the characteristics of the image carrier, the decomposition of the luminance component of the color image, and then scrambled watermark image embedded low-frequency position. On the information detected n times anti-Arnold scrambling, you can extract the watermark image Platform: |
