| 摘 要： | 讨论了在变换域中的基于DWT数字图像公开水印技术,以基于位平面的思想,在小波多分辨率分解后的各子图中嵌入多个相同版本的水印信息,再基于统计的原理提取水印.实验表明此算法效率较高、鲁棒性较强、透明性较好.

| Abstract: | The digital image public watermarking techniques in DWT domain are discussed.Based on bit plane theory,watermarking information of same versions are embedded in the sub-figures which are decomposed through small wave high resolution.And then watermarking is extracted on the basis of statistics principle.The experimental results show that this method is effective,and the watermarking is transparency. |
