| 摘 要： | 提出了一种新的基于SVD的小波域自适应量化盲水印算法;对有意义的二值水印图像进行预处理置乱后,该算法结合人类视觉系统特性采用不同的嵌入策略把0/1水印值分别嵌入到图像三级小波分解后的中低频子带和高频子带系数中,并结合小波零树原理在中低频子带进行嵌入水印,而在高频细节子带则利用奇异值良好的稳定性能来进行水印的嵌入;仿真结果表明:与传统的算法相比,该方法在针对高低频的多种攻击下具有良好的鲁棒性。

| Abstract: | A Blind auto-adapted watermarking Algorithm based on wavelet domain and SVD is proposed.Acording to the human visual system,this alogorithm uses different tactics embed the 0/1value into low frequency and high frequency detail bands of the 3-wavelet deposition.In the low frequency detail bands,the wavelet zerotree structure principle is adopted to embed the watermark.In the high frequency,the stability of SVD is used to embed the watermark.Simulation results indicate that this alogorithm is more robust under various attack than the tradition algorithm. |
