| 摘 要： | 本文提出了一种基于零树的小波水印方案。该方案首先利用Haar函数在小波域执行水印，然后运用遗传算法在某个小波系数上恰当选择零树进行水印嵌入，并通过控制迭代次数和嵌入强度保证水印的特性。仿真结果表明该算法得到的图像水印具有良好的不可见性，同时也保证水印图像在常规的攻击下提取出的水印具有鲁棒性。

| Abstract: | A watermarking wavelet algorithm based on zerotree structure is proposed in this paper.It is carried on in wavelet domain by applying Haar function. And then, basing on the wavelet coefficients, zerotree is selected appropriately by using genetic algorithm to implement the embedding of watermark, which meanwhile guarantees the characteristics of watermark by controlling the number of iteration and the embedding strength. The simulation results indicate that the image watermarking obtained by the proposed algorithm has perfect invisibility and is robust to some common attacks at the same time. |
