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
else
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)

sexy_and_drnd
sexy函数可以将MATLAB符号表达式变成人们书写形式的表达式。
drnd函数是我写的可以生成服从任意有限离散分布的随机数。(sexy function can be MATLAB symbolic expression of the people into written form expression. Drnd function is I write can generate obey arbitrary finite discrete distribution of random numbers.)
