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.)

主要是对图像实现DFT,DCT变换，利用二维小波分析对图像作二层小波分解，显示条状图，十字图及频谱等(Realize the image is mainly DFT, DCT transform, the use of two-dimensional wavelet analysis of images for the second floor of wavelet decomposition, indicating strip maps, charts and cross spectrum)

这是用matalab生成的rs码的生成，可以研究一下的(matalab rs generated code generation, can look at the)

一般模式的机载双基地合成孔径雷达回波数据产生，收发平台具有不同的速度与方向，均工作在斜视模式(General pattern of airborne bistatic synthetic aperture radar echo data generated transceiver platform has a different speed and direction, are working in the squint mode)

tdma解三对角矩阵，是一个M文件，用在matlab中，编写完整(tdma solution of tridiagonal matrix is ​ ​ a M-file, used in matlab, the preparation of a complete)

This is dialog program. for use playing the music through the serial interface. So, this program is included RS-232.
