一种高容量的图像信息隐藏方案
A high-capacity image information hiding scheme
摘要
Abstract
The steganography mainly has two problems of overhigh compression degree for the processed image and high perception degree for distortion. To solve these problems,a new steganography based on KLT(Karhunen⁃Loeve transform)was developed. An iterative clustering algorithm is introduced into the steganography to obtain the needing solution and analyze the data. The KLT is used to process the image which needs to be hidden. The least significant bit is used for hiding processing for the confidential information. When some information needs to be obtained,the reverse linear transform operation approach is used to acquire the source image according to the original pixel matrix. The practice results prove this method is superior to other commonly⁃used algorithms in the aspects of capacity and signal⁃to⁃noise ratio,and can acquire the image with small distortion.关键词
