| 摘 要： | 本文提出了一种基于小波域的数字水印方案.在嵌入图像之前,对水印进行置乱处理,对图像的小波系数使用离散余弦变换.实验证明,这种方法对常规图像处理有很好的鲁棒性.

| Abstract: | A digital watermarking method based on Shuffling Techniques And Wavelet Transform is proposed in this paper.The image will be changed by DCT firstly .Before embedded into the lower frequency DWT coefficient of the image,the watermarking will obtain an Arnold transform.It is proved by experiment,this method possesses strong robust. |
