摘要

提出了一种利用整数小波变换(TWT)提升方案实现高质量隐写图像的数据隐藏方法。该方法将空间域覆盖图像转换为频率域覆盖图像。该算法分别在CH、CV、CD中的任意一个比特上构造二值图像，将秘密信息隐藏到IWT的详细系数(CH、CV、CD)中，并对该比特进行算术编码压缩。这个方法非常简单有效。

Data hiding in gray scale images using Integer Wavelet Transform

This paper presents a novel data hiding using Integer Wavelet Transform (TWT) through lifting scheme that aims to achieve high quality of stego image. This method transforms a spatial domain cover image into a frequency domain cover image. It hides the secret message into detail coefficients (CH, CV, CD) of IWT by construct a binary image in any of selected bit in CH, CV, CD separately and compresses that bit by using arithmetic coding. This method is very simple and effective.
