dct
在一个图像块中调整两个(或多个) DCT系数的相对大小。将描述一个使用数字图像作为载体的系统。在编码处理中,发送者将载体图像分成8×8的像素块,每一块只精确地编码一个秘密信息位。嵌入过程开始时,首先伪随机地选择一个图像块bi,用它对第i个消息比特进行编码。令Bi=D{bi}为DCT变换后的图像块。
在通信开始前,发送者和接收者必须对嵌入过程中使用的两个DCT系数的位置达成一致,让我们用(u1,v1)和(u2,v2)来表示这两个索引。这两个系数应该相应于余弦变换的中频,确保信息保存在信号的重要部位(从而使嵌入信息不容易因JPEG压缩而完全丢失

Version 1.0- February 2007

This package contains a Matlab implementation of the Fast Kernel ICA
algorithm as described in [1].
Kernel ICA is based on minimizing a kernel measure of statistical
independence, namely the Hilbert-Schmidt norm of the covariance
operator in feature space (see [3]: this is called HSIC). Given an (n
x m) matrix W of n samples from m mixed sources, the goal is to find a
demixing matrix X such that the dependence between the estimated
unmixed sources X *W is minimal. FastKICA uses an approximate Newton
method to perfom this optimization. For more information on the
algorithm, read [1], and for more information on HSIC, refer to [3].
The functions chol_gauss and amariD are taken from and based on,
respectively, code from Francis Bach (available at
http://cmm.ensmp.fr/~bach/kernel-ica/index.htm). The derivative is
