| 摘 要： | 提出一种新的基于证据理论的数据融合的双效水印算法.首先应用水印公式构造特殊的水印嵌入后条件,根据嵌入系数之间的定性分析提取鲁棒水印;利用嵌入系数之间的定量分析能提取脆弱水印,并能准确定位篡改的区域.其次在嵌入过程中还使用纠错码对水印信息进行调和,把水印重复嵌入到图像信息的不同位置,以便利用纠错码的辅助信息来估计出提取的...

| Abstract: | A novel blind double effect watermarking algorithm of data fusion technology is proposed based on evidence theory.Firstly the watermarking formula is applied to constructing such a special condition after embedding,the robust watermark is extracted by the qualitative analysis among embedding coefficients and the fragile watermark is extracted by quantitative analysis among embedding coefficients,the tempered area is able to be located precisely.Secondly the error correction code is contributed to the reconc... |
