| 摘 要： | 目的针对传统数字水印技术的有限性,实现一种新的数字水印算法。方法新算法以小波变换为基础,对原始图像和水印图像进行小波变换,将水印信息嵌入到中频系数中。结果实现了二维彩色图像将为水印信息嵌入到二维图像数据中。结论实验证明,新算法在对彩色图像进行水印处理方面达到较好的效果,具有较好的健壮性。

| Abstract: | Aim With the development of digital multimedia technology,digital watermark has become a popular topic in the field of digital copyright protection.Owing to the shortcomings of the traditional digital watermark methods,analyze the frequency domain watermark algorithm,propose a new digital watermark method.Methods The new method embedded the watermark information into intermediate frequency.Results Accomplish embedding 2d true color images as watermark information into the 2d color images.Conclusion Experimental results show that the new method has an excellent effect in 2d true color images digital watermark processing.The experimental results also demonstrate that the new method has a good robustness. |
