Description: 基于虚拟光学信息隐藏理论提出了一种三维空间数字水印算法1 该数字水印算法能成为
一种多媒体数据产权保护的有效方案1 对算法的测试结果表明,该算法对于噪音叠加、剪切、旋转、
有损压缩等常见的图像处理操作具有较高的鲁棒性1 由于引入了虚拟光学信息隐藏思想,将虚拟
光路的几何结构参数作为密钥,设计出了多重“锁”和多重“密钥”1 随机模板编码技术的引入,更进
一步提高了数字水印系统的密钥空间. 仿真实验结果表明该算法具有很好的安全性1- A new approach to digital watermarking in three2dimensional (32D) space based on virt ual2optics
and random mask encoding is presented. The watermarking algorithm can offer an effective solution to t he
issue of copyright protection of multimedia data dist ributed via t he communication channel . The result s
show t hat t he embedded watermark is robust to normal data manip ulations , such as adding noise ,
cropping , rotation , and J PEG compression. Because t he design concept and met hodology based on
geomet ric parameter s of Virt ual2Optics was adopted , t he proposed 32D watermarking system has good
security. There are large degrees of f reedom existing for designing a security lock ( s)/key ( s) , including
multiple lock ( s)/key ( s) and multi2dimensional lock ( s)/key ( s) . Numerical experiment s are performed to
validate the p roposed met hod , and sensitivities of some parameter s are quantitatively analyzed and
illust rated. The possible dimensions of keys are ro Platform: |

Description: 数字水印算法，首先从原始图像中读出水印，再将水印图像进行压缩，然后将嵌入水印的图像读取出来，在对图像进行攻击后，对图像进行多次分解和重构，最终图像与原图应该差别不大
-The image digital watermarking, first the original image readout watermark, watermark is compressed, and then the watermark is embedded in the compressed image is read out, after the attack on the image, after multiple decomposition and reconstruction images and image should be little difference

Description: 将要嵌入的多张水印图利用不同正交码调制，之后嵌入到被嵌入图片的小波变换系数中，对小波系数做逆变换，得到已嵌入水印图的图像。利用逆过程可提取出被嵌入的图像(The multiple watermark images to be embedded are modulated by different orthogonal codes, and then embedded into the wavelet coefficients of the embedded images, and the inverse coefficients of the wavelet coefficients are transformed to get the image with embedded watermark. The embedded image can be extracted by the inverse process) Platform: |
