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)

CFAR-detection-algorithm
A novel constant false alarm rate(CFAR)detection algorithm is proposed in this paper．The
Biparameter CFAR detection is applicable tO Gaussian noise in non—coherent integration for radar dim target
detection algorithm．The paper analyzed the probability of false alarm in theory．Monte—Carlo simulations
demonstrate that the Biparameter CFAR processor has achieved about 5 dB SNR gains in detection performances
comparable to the conventional cell—averaging CFAR processor．
