| Abstract: | This paper presents the general model of digital watermarking embedding and extracting processes and their analysis.Then the robustness of watermarking system against image processing is examined and the reason why detection errors occur in the watermarking extracting process is identified.Based on the result,an improvement is carried out on the watermark extracting process by designing a deconvolution filter that attempts to undo the effect of watermarking attack.The design is achieved by using the neural network technique.Numerical experiments with the DWT-based watermarking system show good performance as we wished. |
