| 摘 要： | 提出了一种结合离散小波变换（DWT），离散余弦变换（DCT），感知模型（HVS）及矩傅立叶矩阵描述子（MFMD）的图像数字水印方案。该方法把原始图像进行二维DWT分解，保留其高频细节部分，然后对小波逼近子图进行二维DCT变换并结合HVS进行水印嵌入。水印的检测则采用了相关性与MFMD相结合的方法。实验结果表明该水印方案很好地实现了水印系统所要求的基本特性，诸如嵌入有效性，保真度，数据有效载荷及鲁棒性等等。

| Abstract: | A scheme of digital image watermarking using the combination of DWT,DCT,HVS and MFMD is proposed.At first,the original image is decomposed by 2-D DWT and the detail sub-bands are reserved.Then,the approximation image is transformed by 2-D DCT and embedded with watermark by using HVS.The watermark is detected by using the combitation of correlation and MFMD.The experimental results demonstrate its good performance with watermarking system's basic characterist:embed validity,invisibility,effective load,robustness and so on. |
