摘要
介绍了数字水印技术实现的一般原理,提出了一种基于DWT(离散小波变换)的彩色图像数字水印算法.通过MATLAB仿真结果表明,利用该算法嵌入的水印具有信息量大、不可见性好等优点.
This paper introduces the common principles through which digital watermarking is implemented and proposes a color image digital watermarking algorithm based on DWT. Simulation results show that embedded watermarking has the characteristics of abundant information and better invisibility.
