本文提出了一种利用整数小波变换和压扩技术的数字图像的新型可逆数据嵌入方法。该方案利用高频子带整数小波系数的类拉普拉斯分布，有利于压缩和扩展函数的选择，并使标记图像与原始图像之间的失真较小。实验结果表明，该方案优于最先进的可逆数据隐藏方案。
This paper presents a novel reversible data-embedding method for digital images using integer wavelet transform and companding technique. This scheme takes advantage of the Laplacian-like distribution of integer wavelet coefficients in high frequency subbands, which facilitates the selection of compression and expansion functions and keeps the distortion small between the marked image and the original one. Experimental results show that this scheme outperforms the state-of-the-art reversible data hiding schemes.
