【摘要】 随着互联网的发展,数字产品的版权问题引起了人们的关注,但是遥感图像的版权保护却没有受到重视。数字水印技术作为数字产品版权保护的有效方法之一,已经广泛应用于各类数字图像的版权保护中,但并未涉及遥感图像的版权保护。该文提出将成熟的小波域数字水印方法应用于遥感图像的版权保护,仿真实验取得了满意的结果,证实了数字水印保护遥感图像的版权是可行的、有效的。同时考虑到遥感图像不同于一般图像的特点,寻找适应于遥感图像自身特点的水印算法将是今后继续研究的重点。更多还原

【Abstract】 With the development of science, copyright of the digital product arouses people’s attention, but copyright protection for remote sensing image hasn’t gotten recognition. As a valid method of digital product copyright protection, digital watermark technology is applied to various digital images expect the remote sensing images. The paper presents digital watermark technology based on wavelet transform, and experiments obtain a satisfactory effect, so the digital watermark technology for remote sensing image copyright protection is feasible and effective. In view of the characters of remote sensing images, it is our research emphases in the future to search an algorithm for the characters.更多还原
