直接序列扩频伪码跟踪simulink仿真程序，仿真PN码捕获，跟踪过程完整过程。(Direct sequence spread spectrum code tracking simulink simulation program, emulation PN code acquisition process complete process of tracking.)

a self- embedding block wise fragile watermarking scheme with tamper detection and content recovery capability. The proposed scheme embeds the shuffled extensive ten bit Recovery data and two bit Authentication data of the image block into the least significant bits (LSB) of its corresponding mapping block.The integrity of a test block is decided by comparing 2×2 non overlapping block of the test block with its corresponding mapping block. Experimental results show that the suggested scheme outperforms conventional self recovery fragile watermarking algorithms in alteration detection as well as in tamper recovery of the image.

使用Matlab实现函数的傅里叶级数展开(Implement the function using the Matlab Fourier series expansion)

这个函数读取各个比特的信息处理器和操作 系统，包括： *中央处理器的名字 *时钟速度 *处理器缓存的大小（二级） *号的物理处理器核心 *操作系统名称和版本 这是由程序/处理器（系统），sysctl（苹果）或命令行工具（窗口）。 需要在r2010a或以上。(This function reads various bits of information about the CPU and operating system, including: * CPU name * CPU clock speed * CPU Cache size (L2) * Number of physical CPU cores * Operating system name & version These are provided by /proc/cpu (Unix), sysctl (Mac) or WMIC (Windows). Requires MATLAB R2010a or above.)

利用matlab进行图形的二维傅里叶变换(Using matlab graphical two-dimensional Fourier transform)

可用于高光谱图像处理的自己编的PCA函数,Matlab版的.主要作用是降维.(the pca function is used to hyperspectral image processing.)
