【摘要】 随着数字技术、互联网等的飞速发展,人们对于数字产品版权保护的问题越来越重视,数字水印已经成为一种有效的数字产品版权保护方法。本文提出一种基于内容的自适应离散傅立叶变换(DFT)域数字水印算法,并用于遥感图像版权的保护。结合遥感图像的自身特点进行仿真实验,取得了满意的实验结果,证实了该方法的可行性。更多还原

【Abstract】 With the rapid development of digital technology and Internet,people take more and more attention on the problem of copyright of the digital product protection.Digital watermarking has become a valid methord of digital product copyright protection.This paper proposes a method of content-based adaptive DFT domain digital watermarking algorithm for remote sensing image copyright protection.The satisfactory experimental results show that the proposed method is feasible.更多还原
