| 摘 要： | 数字水印技术是实现数字产品产权保护的一种有效手段。本文提出了一种基于整数小波变换的数字图像水印算法。首先将原始图像进行分块，逐一对每块子图进行整数小波分解，然后将置乱后的二值图像嵌入到低频系数。实验证明该算法具有较好的隐蔽性和鲁棒性。

| Abstract: | Digital watermarking technology is an effective method for copyright protection of digital products.The paper presents an algorithm for digital watermarking of image based on Integer Wavelet Transform.First of all,original image is divided into blocks,each subgraph for integer wavelet decomposition,and then the binary image after scrambling embedding.Experiments show that the algorithm has a better concealment and robustness. |
