摘要
提出了一种将水印图像进行Arnold置乱后嵌入到经DCT域进行变化的载体图像中的数字水印算法。算法研究结果表明水印具有较好的不可见性及健壮性。同时,文中采用不同图像处理方式对嵌入水印后的图像进行了攻击实验,实验表明该算法对于JPEG压缩具有较好的鲁棒性。
A digital watermarking algorithm based on secret image scrambling and discrete cosine transform （DCT） domain is proposed. Research results show that it is a better invisible and highly robust algorithm. Different image processing schemes are used to attacking experiments. Tests indicate that it is a highly robust algorithm against JPEG compression.
