LSFS
说明: 有监督的特征选择和优化程序MATLAB代码,基于最小二乘算法。内有测试数据,和详细程序说明(Least-Squares Feature Selection (LSFS) is a feature selection method for supervised regression and classification. LSFS orders input features according to their dependence on output values. Dependency between inputs and outputs is evaluated based on an estimator of squared-loss mutual information called LSMI)

dcthide
dct隐写技术matlab实现资料。算法原理:通过在一个图像块中调整两个DCT系数的相对大小,隐藏秘密信息。
将载体图像分为8×8的块,做二维DCT变换
用来表示选中的两个系数的坐标对于第i bit秘密信息
if(要隐藏信息‘1’)
make

逆DCT变换,还原图像
(dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)
