NASA开源的匹配追踪分解算法，用于信号分解以及特征提取。(Matching Pursuit Decomposition is a powerful and effective iterative algorithm for signal decomposition and feature extraction. Matching Pursuit Decomposition decomposes any signal into linear combinations of its dictionary elements or atoms.)

利用matlab进行图像数据的剪裁，需要提供需剪裁影像的中心点行列号；RMSE.m是计算均方根误差RMSE的程序。(Using MATLAB to tailor the image data, we need to provide the central point and row number of the image to be tailored. RMSE.m is a program to calculate the root mean square error RMSE.)

DEM数据处理，有贴纹理及漫游程序，自己在其他网上下载的 希望对做三维的朋友有所帮助(DEM data processing, has the stick texture and roaming)

说明：  编程实现灰度图像的频域滤波算法。使用Matlab实现不延拓和延拓两个版本。对于延拓和不延拓版本，在理想低通滤波器、巴特沃斯低通滤波器和高斯低通滤波器上比较两者的区别；对于延拓版本，比较不同参数设置对上述三种滤波器滤波结果的影响。(Program to realize the filtering algorithm of gray image in frequency domain. Matlab is used to realize two versions of no extension and extension. For the extension version and the non extension version, the differences between the ideal low-pass filter, Butterworth low-pass filter and Gauss low-pass filter are compared; for the extension version, the effects of different parameter settings on the above three filter results are compared.)

计算特征的汉明距离作为特征匹配相似度的评价标准(The Hamming distance of the feature is used as the evaluation criterion of feature matching similarity)

运动的小球、一般本科需要的课后作业设计。有兴趣的可以下载看看(The ball movement, the general undergraduate required homework designs. Interested parties can download and see)

基于轨迹划分的异常轨迹检测方法。首先采用两种分段粒度将每条轨迹分为若干子轨迹线段，然后，在基于距离的异常检测方法的基础上，引入调整系数的概念，采用密度与距离相结合的方法进行异常轨迹检测。 (Abnormal trajectory detection method based on trajectory partition.Firstly each trajectories should be divided into several substrajectories using two granularities. Then the notion of adjustment coefficient is introduced on the basis of distance based anomaly detection method, and the abnormal trajectories are detected combining density and distance. )
