说明：  本资料为MATLAB GUI设计的简单例程，包括两个源文件（.m和.fig)。其具体的功能为图片的提取及二值化处理。(This information is designed for simple MATLAB GUI routines, including the two source files (. M and. Fig). The specific function of the extraction and image binarization.)

MUSIC算法原理及其Matlab仿真.设有m个阵元，p个信号源，x(n)为观测数据,令其特征值分解,然后把特征矩阵U的列向量分为信号特征向量和噪声特征向量(MUSIC Algorithm and its Matlab simulation. With one array element m, p a signal, x (n) for the observed data, so that it eigenvalue decomposition, and then the column vector of characteristic matrix U eigenvectors into signal and noise characteristics vector)

参考Matlab提供的模块建立简化的三相锁相环的仿真模型，只保留必要的步骤，如abc-dqz只计算Vq，去除频率反馈模块和自动参数调整模块等。 建立单相锁相环的计算模型  简化单相锁相环的系统结构，保留必要的PI控制器等模块  验证并讨论输入信号频率在45-65Hz变化时设计的锁相环的动静态性能  仿真并分析三相输入信号包含谐波、不平衡和直流偏移时锁相环的锁相结果(Reference Matlab provides three-phase PLL module to establish a simplified simulation model, retaining only the necessary steps, such as abc-dqz counting only Vq, remove frequency feedback module and automatic parameter adjustment module.  simulation and analysis of the three-phase input signal contains harmonics, unbalance and DC offset PLL phase-locked Results)

Inverse discrete cosine transform of an image

MUSIC算法的DOA谱估计，能够实现MUSIC算法的MATLAB仿真。(MUSIC algorithm DOA spectrum estimation, MUSIC algorithm MATLAB simulation.)

PCA可用于图像检测的盲取证方面，效果非常好(PCA can be used for blind image forensics testing, the effect is very good)

UKF和KF的实现。并通过输出图像比较两者的区别(UKF and the KF implementation. By comparing the difference between the output image)

说明：  复杂网络BA模型matlab代码，返回网络图的邻接矩阵，代码中采用稀疏矩阵，极大地释放内存，提高效率。(BA model complex network matlab code, return to the network adjacency matrix, the code used in sparse matrix, which greatly release memory and improve efficiency.)
