摘要:

针对数字遥感影像大尺度、多波段、高保真的特性,提出了一种新颖的版权保护方案.理论分析了第一奇异值向量方向的稳定性;通过比较某一参考向量分别与两个选定数据块的第一奇异值向量的夹角关系,建立单波段图像水印特征;然后为遥感影像的多波段特性提出了水印检测的快速策略与一般策略.实验表明该方案对波段攻击与灰度攻击、组合攻击等保持图像内容的操作具有较强的鲁棒性.

关键词: 数字水印, 奇异值向量, 遥感影像, 波段攻击, 灰度攻击

Abstract:

A novel copyright protection scheme is proposed for large scale,multi-band and high fidelity of digital remote sensing image.The stability of the first singular value vector direction is analyzed.In extracting watermarking feature for single band image,one bit feature is generated by comparing the angle size relationships that come from the first singular value vector of two selected data blocks and a reference vector.Next,the fast watermark detection strategy and general strategy are proposed especially for the multiband property of remote sensing imagery.The experimental results show that the proposed scheme is robust to band attack,gray attack,combination attacks and some other content-preserved operations.

Key words: digital watermarking, singular value vector, remote sensing imagery, band attack, gray attack
