| 摘 要： | 以图像信息安全问题为背景,介绍了整数的进制数表示法及其在数字图像信息隐藏中的应用,并给出了相应的算法和仿真实验结果.按照此方法,可将一幅灰度图像隐藏于一幅相同大小的彩色图像中,视觉上不影响该彩色图像的质量.隐藏的数据量大,算法简便易行,且可以无失真地恢复出原始图像.与数字图像置乱相结合,可进一步提高安全性.

| Abstract: | With the security problem of image information as the background,the system expression of integer and its application in image hiding are introduced.The relevant algorithm and simulation results are given.With this method,a gray image can be hided in a color image of the same size.In this vision,the quality of the color image is almost the same.The data volume for hiding is large,it is easy to realize this algorithm and the primary image can be restored completely.The security can be improved combined with digital image scrambling. |
