一种在图像中嵌入有意义文本信息的新型鲁棒水印算法
摘 要
提出了一种在图像小波域中嵌入文字的新型鲁棒水印算法,并对嵌入的文字进行混沌加密和BCH纠错编码。实验结果表明,该算法增大了水印数据的嵌入容量,提高了抗常见攻击的能力。

A New Robust Watermarking Algorithm Embedding Text Data into Image
() Abstract
This paper brings forward a text embedding digital watermarking method based on image's DWT domain,meanwhile,using the chaotic sequences to encrypt the text data and BCH code to correct them.The experimental results show that the method enlarges watermark capacity and improves the ability to resist the usual attack.
