摘 要: | 针对小波变换提出一种双自适应算法,并将该算法应用于JPEG2000压缩过程中的小波变换,在此基础之上,又提出一种适合于JPEG2000的数字水印算法.该算法利用JPEG2000压缩中的双白适应小波变换,将水印嵌入到量化后的小波系数中.实验证明,该算法具有较好的不可见性和较强的鲁棒性.

Abstract: | In this paper, we propose a kind of double adaptive algorithm for wavelet transform, and apply it to JPEG2000. Based on the algorithm, we propose a digital watermarking algorithm which fits JPEG2000. The algorithm makes use of double adaptive wavelet transform and embeds watermark in the wavelet coefficients. The experiment proves this algorithm has better robustness and detection. |
