| 摘 要： | 提出一种基于混沌映射的小波域数字图像水印新算法。将含有版权信息的二值图像作为水印,利用两个混沌映射的切换得到一个混沌序列,用其对水印图像进行加密。并用二维混沌映射对嵌入位置进行加密。算法根据HVS特性得到嵌入点的局部掩模函数,实现了水印在原始图像小波域中的自适应嵌入。实验结果证明该算法具有良好的鲁棒性。

| Abstract: | In this paper, on wavelet domain, a new adaptive watermarking algorithm is proposed. The binary image is used as watermark. It is encrypted by a chaotic sequence. The algorithm sequence is got from two chaos maps. And the embed place is encrypted by a 2-D chaos mapping. Then the shelter function of the embed place is got from the features of HVS. The algorithm can insert watermark on wavelet domain of original image. The experimental results show the algorithm has very excellent robustness. |
