摘　　要：利用树状小波分解结合人类视觉系统(HVS)的特性,同时运用线性混合的办法,在载体图像中自适应地嵌入多个数字水印副本;在提取水印时,在每个块中使用独立分量分析ICA的方法提取水印,并对提取出的多个水印副本图像进行融合操作,以提高水印的鲁棒性。仿真试验表明该方法是有效的、可行的。Multiple copies of digital watermarking were embedded into the carrier image using the characters of tree-structured wavelet decomposition and human vision system, and them was extracted based on ICA algorithm . Finally, these extracted copies were fused by PCA image fusion algorithm for improving robustness of digital watermarking. Simulated experiment results show that this method is effective and feasible.
