摘要
基于图像小波分解的子图特性,将原始水印进行了矢量分解,然后给出其嵌入的算法,并对算法进行了仿真实验.仿真实验表明,该算法能够很好地抵抗对图像噪声、滤波、几何等攻击,表明该算法有较强的稳健性.
The original watermarking is vector decomposed by using the characteristics of subgraph which is wavelet decomposed,and then its embedded algorithms are given in the paper.Simulation experiments show that the algorithm is more resistive to the attack of noise,filtering and geometry on the image,which means the algorithm is rather robust.
