Description: 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
