摘要
数字水印技术是解决多媒体数据版权保护问题的有效手段之一,论文提出了一种基于对图像水印位平面分解的数字水印方法。文中首先介绍了图像水印信号的生成过程,然后详细地探讨了该方法的实现过程,最后利用试验对该方法进行了论证,试验结果表明,该方法具有图像失真小、鲁棒性好、可操作性强等优点。
Digital watermarking technique has been an effective solution to protect the copyright of multimedia data,This paper brings forward a digital watermarking method based on the bit plane decomposition of the image watermark-ing,Firstly,the building process of the image watermarking is introduced.Secondly it discusses the process of this method at length.At last,it demonstrates this method is right by some tests.These tests prove the method could make image distortion low and be robust,easy to use.
