| 摘 要： | 提出了一种基于DWT的有意义图像的水印算法。算法中利用乘性隐藏方法在原始图像的三级小波变换后的水平细节子带HL3和垂直细节子带LH3来嵌入一幅有意义的水印图片,并重复进行嵌入。实验结果表明,该算法在对图像进行高斯噪声、椒盐噪声、中值滤波攻击有较好的隐蔽性和鲁棒性。

| Abstract: | This paper proposes that a image of meaningful watermarking algorithm based on DWT. Through using multiplicatively that horizontal detail subband HL3 and vertieal detail subband LH3 of the image wavelet embedded in watermarking. The experiment results show that the algorithm has good imperceptible and robustness on Gaussian noise .salt＆pepper noise and median filter. |
