| 摘 要： | 提出一种结合置乱技术的小波域图像水印算法。利用Arnold置换方法对水印图像作时域上的变换，将秘图变换成无意义的图像，达到加密的效果，再根据提出的一种小波变换域的数字水印算法，将水印图像嵌入到小波变换的不同方位的重要系数当中，文中实现了标志图像水印。实验结果表明，该水印算法对图像处理有较强的鲁棒性。

| Abstract: | An watermark algorithm based on discrete wavelet transform(DWT) and Arnold transform is represented.The watermark image is first transformed by Arnold transform to an unmeaning image in time field,then inserted watermark image into key coefficients of DWT different direction,and realized sign image watermark.Experiments show that this algorithm is robust against image processing. |
