Abstract:Based on the fine properties of cardinal multiwavelet, we propose a novel algorithm of dual color images watermarking in this paper. The realization of this scheme only requires taking the discrete multiwavelet transform (DMWT) or inverse DMWT (IDMWT) to the R, G, B elements of the color host image and watermarked image respectively, so the technique greatly improves the watermarking efficiency. Moreover, the experimental results show that the watermarking system has good transparency and robustness.
Keywords:cardinal multiwavelet  dual color images watermarking  robustness  transparency
