| 摘 要： | 为了保护信息,防止信息遗失或泄密,提出了一种空域和变换域相结合的基于关键区域的彩色图像水印算法,应用于彩色静止图像,讨论了计算误差和图像复原等问题,并给出了解决方法。该算法水印信息容量大,实验证明可以抵抗裁剪、伸缩、旋转等几何攻击。

A Color Image Watermarking Algorithm based on Key Area |
| |
| Abstract: | In order to protect information,and prevent information from losing and revealing,this paper presents the color image watermarking algorithm combined with spatial domain and transform domain based on key area,which is used to the stationary image.Several problems such as computation error and image restoring,are also discussed and solutions are provided.Experiments show that the watermarking can embed more watermarking information and resist simple geometric assault,such as cutting,stretching and rotating. |
