代码描述

中文说明:数据隐藏技术有了重要的作用,随着密集的调动的多媒体内容和秘密通信的快速增长。隐写术是艺术的隐藏信息的预防检测.小波变换的方法得到了广泛的接受,在图像处理中。执行离散小波变换的多分辨率分析和空间频率定位.该隐写算法对哈尔和 daubechies 小波变换系数中嵌入秘密图像的原始图像的工程。在这里离散小波变换用于转换两个原始图像和秘密图像。所以离散小波变换允许完美嵌入隐藏的信息和重建。与当前的变换域数据隐藏方法相比这种方案可以提供高效的容量为数据隐藏原始图像质量的前提。


English Description:

Data hiding techniques have taken important role with the rapid growth of intensive transfer of multimedia content and secret communications. Steganography is the art of hiding information in ways  that  prevent  detection.  The  wavelet transform has gained widespread acceptance in image processing. Discrete Wavelet Transform performs a multi-resolution analysis and space frequency  localization.  The  proposed Steganography algorithm works on the haar and daubechies wavelet transform coefficients of the original image to embed the secret image. Here discrete wavelet transforms is used to transform the both original image and secret image. So discrete  wavelet  transforms  allows  perfect embedding  of  the  hidden  message  and reconstruction. As compared to the current transform domain data hiding methods this scheme can provide an efficient capacity for data hiding without sacrificing the original
