| Abstract: | This paper has proposed a digital watermarking algorithm based on wavelet coefficient subparagraph,which has high robustness to common image processing operation.The algorithm gives a method of completely blind detection,in which the watermark recovery does not require the original image and watermark information,and the accuracy of watermark detection is very high. |
