| Summary: | This paper has brought forward an improved non-blind watermarking algorithm based on discrete wavelet transform.
Watermarking applies special meaningful color image. Before embedded watermark, the algorithm requires needs the
watermarking image and carrier image to separate color and transform discrete wavelet. Then the watermark’s low
frequency sub-graph and high low sub-graph are respectively embedded into carrier image using additive watermark
embedding rules and iterative mixed method. The experiment results have showed that the algorithm has good
concealment and improve the robustness of the algorithm. |
