Hengfu Yang · Jisuanji gongcheng · 2008
By using data fusion,this paper proposes a robust digital watermarking algorithm.Multiple copies of digital watermarking are embedded into the carrier image by exploiting the characteristics of tree-structured wavelet decomposition and human visual system,and Independent Component Analysis(ICA) method can be used to extract these copies.These extracted copies are fused by PCA image fusion algorithm so as to improve the robustness of the algorithm.Simulation experiments show that the scheme is effective,and achieves higher transparency and strong robustness to common image processing attacks.
