摘要
文章提出了一种新的小波域奇异值分解的算法,通过对原图像小波分解后的系数进行奇异值分解来嵌入水印,具有很强的抗JPEG压缩能力,并在嵌入水印时采用了自适应嵌入的方法提高了不可见性,还采用了一种基于队列置换的图像置乱技术,提供密钥增加了系统的安全性。
A new wavelet domain algorithm using singular value decomposition is proposed, which embeds watermark on coefficients of wavelet domain, by singular value decomposition. It is robust at jpeg compression, and a self-adaptive method is used while embedding watermark to improve the imperceptibility, a new image scrambling technology based on queue transformation is adopted, it provides keys that also improved the security of the system.
