- W2371964145 abstract "Digital watermarking is an effective means of information hiding and copyright protection. For general digital watermarking algorithm can not balance the visuality and robustness,this paper proposes a robust blind watermarking algorithm of JPEG2000 images.It designes a Linear Shift Feedback Register of m+n bits to scramble the watermark image,then choses the low frequency which is processed after the wavelet transform to embed the watermark bit.It completes the watermark embedding with the quantification processing.It improves the watermark embedding speed. According to the nature of LSFR, the watermark is detected and to be shifted to restore the watermark image.So it achieves blind watermark extraction.Experiments show that, the algorithm has a good visuality and robustness." @default.
