| 摘 要： | 提出了一种基于提升整数小波变换的数据隐藏的算法.该算法把秘密数据先进行无损加密和压缩,而后嵌入到图像整数小波变换后的高波子带系数中.解决了提取信息中的虚假信息取舍和小波反变换时的灰度值溢出问题.对比实验表明:能够嵌入大容量的数据,而且保持良好的视觉效果.

| Abstract: | Based on the principle of lifting integer wavelet,propose an improved algorithm of data hiding.It has embedded compressed secret data in integer wavelet high frequency subband coefficient whose image has changed with integer wavelet.Resolved the problem whose coefficient is used for embedding when extracting the embedded data,increase size of secret data,prevented overflow and underflow problem of grays.We have analyzed the results of experiments.Experiments show the method can embed secret information in great size.It is demonstrated that changed images have very good vision effect. |
