摘要
该文探讨了数字图像的置乱与融合,在此基础上提出了一种空间域数字水印的嵌入方法。在该算法中,置乱用于数字水印图像的预处理和后处理;融合用于将水印图像嵌入到载体图像。实验分析证明,该算法可以方便快速地实现水印算法,并且具有一定程度的鲁棒性。
This paper discusses a spatial watermarking algorithm method which based on digital image scrambling and amalgamation,and with this understanding it brings forward a spatial watermarking algorithm. In the scheme,scrambling technology is used as pre-process and post-process of digital watermarking image,and amalgamation is used to hide a watermarking image into the carrier image. Examples show that the scheme could be expediently and quickly realized,and it is robust in a certain extent.
