一种实用的交互式多模型跟踪算法IMM，真实好用，测试过(A practical interactive multi model tracking algorithm IMM, which is true and useful and tested)

说明：  1到40的无重复随机抽样的程序，其中抽取数目为参数，可调节(1 to 40 repeated random sampling procedure, which extract the number of parameters can be adjusted)

The region is iteratively grown by comparing all unallocated neighbouring pixels to the region. The difference between a pixel s intensity value and the region s mean, is used as a measure of similarity. The pixel with the smallest difference measured this way is allocated to the region.

一个ldpc码的寻找围长（girth）为10的程序(Ldpc code to find a girth (girth) of the program 10)

This programe provides SER analysis of amplify and forward cooperative protocol using QPSK modulation. Results are compared with theoratical results for QPSK modulation with AWGN and Rayleigh fading channels

FCM Data set clustering using fuzzy c-means clustering. [CENTER, U, OBJ_FCN] = FCM(DATA, N_CLUSTER) finds N_CLUSTER number of clusters in the data set DATA. DATA is size M-by-N, where M is the number of data points and N is the number of coordinates for each data point. The coordinates for each cluster center are returned in the rows of the matrix CENTER. The membership function matrix U contains the grade of membership of each DATA point in each cluster. The values 0 and 1 indicate no membership and full membership respectively. Grades between 0 and 1 indicate that the data point has partial membership in a cluster. At each iteration, an objective function is minimized to find the best location for the clusters and its values are returned in OBJ_FCN.

说明：  一种路径规划算法，算法的主要功能是实现无人机的路径规划功能(A path planning algorithm. The main function of the algorithm is to realize the path planning function of UAV.)

　　　以X射线检测焊缝图像为研究对象，针对石油焊管管端焊缝生产检验 中线阵列探测器实时成像的X射线数字图像存在的对比度不高、图像噪声及背景 起伏较大、焊缝边缘模糊且纹理较多的特点。(　　This task takes the X一ray weld seam image as the research object, in view of the X一ray image characteristics of low contrast, high image noise and fluctuated background, fuzzy weld seam edge and more texture with linear diode arrays real一time imaging in the petroleum welded pipe.Matlab simulation software is used to analysis methods of smoothing noise, gray transform enhancement, and image segmentation for image processing.)
