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

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)
