JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))

基于大津法和迭代法的图像二值化程序，相当于利用该方法进行了图像的分割，源码已调试，很好使！(Based on the Otsu method and iterative method of image binarization procedure is equivalent to using the method of image segmentation, source code has been debugging, very good to make!)

图像手动取点用matlab完成，用鼠标点得到点的坐标(Images manually check point)

在VC++6.0开发环境下，图像中值滤波的源码实现，编译即可运行~(In VC++6.0 development environment, the source image median filter implementation, the compiler can be run ~)

MATLAB提取LBP纹理特征源码，可以使用(extract LBP texture features source code in MATLAB, you can run this program directly)

说明：  matching pursuit algrithmic

实现约瑟夫图像置乱加密解密，完整版,可以进行图像加密解密分析(Joseph image scrambling encryption and decryption, complete version)

非负矩阵分解法，这一种新型的子空间分解方法，增加了非负性约束，比PCA、ICA更有效(Non-negative matrix factorization method, which a new type of sub-space decomposition method, an increase of non-negative constraint, compared with PCA, ICA is more efficient)

TBD，检测前跟踪算法的仿真程序，比较多的文件，自己区分(TBD, tracking algorithm pre-test simulation procedures, a relatively large number of documents, to distinguish between their own)

机载正侧视SAR雷达仿真和成像，使用matlab编写，直接运行可用(Simulation and imaging of airborne forward-looking SAR radar)
