A Robust Digital Watermarking Algorithm Based On Pre-processing Method
(0) In recent years,with the development of computer and networking technology,much more attention has been raised to digital watermark technology.The robustness and invisibility are two main indicators of the digital image watermarking system,and the combination of watermark pre-processing and embedding watermarking algorithm can improve the robustness and reduce error rate.In this paper,the algorithm can extract watermark without the original image,and realize a blind detection of watermark.The experimental results show that this algorithm is good at invisibility,and has good robustness to the attacks of down-sampling,noise,format converting,filtering.
