摘　　要：遥感图像是各种传感器所获信息的产物,是遥感探测目标的信息载体,它的版权保护有着自身的特性。普通图像仅仅是"Picture",只是满足人类视觉的需要,而遥感图像除了本身作为"Picture"之外,还包含有"Data"。这里从遥感图像区别于普通图像的特征入手,针对数字水印二个最基本要求———不可感知性和鲁棒性二个方面加以研究分析,并结合二种典型遥感图像的水印算法,分析遥感图像嵌入水印前后,对遥感图像自身属性和应用的影响,从而为遥感图像数字水印算法研究提供评测标准和依据。Remote sensing image is a production of informations from a great variety of sensors and it is information carrier of exploration objects.And its copyright protection is of its own characteristics.Common images are only pictures and they only satisfy human vision,while remote sensing images are not only pictures,but also data.Based on the above analysis,the paper studies two basic requirements of digit watermarking,such as imperceptibility and robustness,and analyzes the effect on the haracteristics and application of remote sensing images before and after embedding watermarking.By combining two typical watermarking arithmetic of remote sensing images,standards and foundations of evaluation for remote sensing images are presented.
