读入视频，将视频转换成JPG格式的图片，并获取所需要的图片。(Read video,convert video to images and capture needed pictures.)

这是与之前上传的Extract_test_IMFCC里面的一个子函数，pudn程序不能一次上载几个函数，只好分开(This is one subfunction of Extract_test_IMFCC uploaded before.Since pudn.com cannot upload several functions, they must divided.)

在MATLAB7.0中，实现在三维数据中，插入斜面(using MATLAB7.0, show the plane in 3D image)

基于全局图像信息的图像分割代码。matlab(image segmentation matlab code based on image globle information)

里面是一些大家很可能常用到的聚类分析方法有像K均值等分析法，希望能为大家提供一些帮助。(There is probably some people used to the cluster analysis methods such as K-means analysis, We hope to provide some help.)

说明：  多目标货物配装问题是一个复杂的组合优化问题，属于NP难问题，本文用混合粒子群算法求解多目标货物配装问题。混合粒子群算法在基本粒子群算法的基础上，通过引进遗传算法中的交叉和变异的策略，避免了陷入局部最优，加快了达到全局最优的收敛速度。此外，本文提出用权重系数来平衡各目标使各目标都能达到相对较优的效果。(Multi-objective loading of goods is a complicated combinatorial optimization problems are NP hard problems, this paper, hybrid particle swarm algorithm to solve multi-objective problem loading cargo. Hybrid Particle Swarm Algorithm in elementary particle swarm optimization based on genetic algorithm through the introduction of crossover and mutation of the strategy to avoid a fall into local optimum, global optimum to achieve accelerated convergence. In addition, this paper, the weight factor used to balance the various objectives so that the objectives can be achieved relatively better results.)

对AR（4）模型的经典功率谱估计，并与真实功率谱作比较。采用了welch方法，协方差法，burg方法(For AR (4) model of the classic power spectrum estimation, and with true power spectrum for comparison. Welch method using covariance method, burg method)

单基地正侧视条带式SAR仿真，采用的是RD算法(One base is side view of band SAR, RD Algorithm Simulation)

说明：  复杂网络中社区划分算法中利用边介数的经典GN算法(Complex network community partitioning algorithm using edge betweenness classic GN algorithm)
