摘　　要：深入讨论了基于Arnold置乱和小波变换的数字水印算法,使用Arnold变换将水印图像置乱,通过小波变换将水印图像和载体图像进行融合,完成水印的嵌入,实验证明该算法有较好的嵌入效果和鲁棒性。This paper discussed the digital watermarking algorithm based on wavelet transform and Arnold scrambling.First using Arnold transform the watermark image,then fuse watermark image and carrier image by wavelet transform to complete of the embedded watermark.Experiments show that the algorithm has better embedded performance and robustness.
