摘要：Digital image watermark has been studied as object. It analyzed the typical digital watermarkalgorithms based on the space domain and transform domain and key researched watermarkingalgorithm based on discrete wavelet transform. It has designed and improved blind watermarkingalgorithm and color image watermarking algorithm. Finally, based on the two improved watermarkingalgorithm, it has designed a dual watermarking algorithm. Both are separated but related. Itauthenticates dual watermarking algorithm in addition to subjective visual evaluation, but also usenumerical objective evaluation and quantitative analysis. Experimental results show that this dualwatermarking algorithm combines with robustness and concealment.
