In this paper, a robust digital watermarking scheme is proposed, in which the watermark is embedded several times in different places to improve robustness. First, an original image is transformed into a coefficients matrix through bandeletization. Then the watermark image is embedded into different places of the bandeletization coefficients matrix simultaneously guided by human visual system (HVS). Because the number of non-zero wavelet coefficients have been greatly decreased by bandletization and the most information has been concentrated on some regions, this scheme possessed a stronger robustness against the noise attacks. At last, the watermarked image is reconstructed through inverse bandelet transformation. In the process of extracting watermark image, the watermark image is extracted by using independent component analysis (ICA) and principle component analysis (PCA) and image fusion. Experimental results demonstrate that the proposed scheme is possess of a good performance in both imperceptibility and robustness.
