Description: 根据灰度图像信息量大、可视化效果好等特点,提出一种基于灰度图像水印的空间域矢量地理空间数据水印算法,即先将灰度图像水印信息按一定法则进行处理,再将处理后的水印信息嵌入到空间域矢量地理空间数据中,最后对嵌入水印信息的矢量地理空间数据进行检测。文中还对矢量地理空间数据进行了攻击实验,分析表明,提取出的灰度图像水印具有较好的鲁棒性效果和一定的实用价值。-According to informative gray-scale images, visual effects and good characteristics of a gray-scale image watermarking based on space vector geospatial data domain watermarking algorithm, that is, first gray image watermark information according to certain rules to deal with, and then treatment after the watermark information embedded into the space domain vector geospatial data, the last of the embedded watermark information vector geospatial data for testing. The article also vector geospatial data on the attacked experiment, analysis showed that the extracted gray-scale image watermarking has good efficacy and robustness of practical value. Platform: |
