Watermarking in binary image based on Arnold transformation
一种基于Arnold变换的二值图像水印算法

In view of the particularity of binary image, a digital watermarking algorithm was proposed for binary image. Watermark was put into an original image by using Arnold transformation and flipping the pixels which met the visual constraints. Experimental results show that the algorithm not only improves the unobtrusiveness and embedding capacity of watermark, but also realizes the blind watermarking.
