提取复杂目标外轮廓

主要是一些经典的视觉跟踪算法的MATLAB代码，tracker包括CREST,CSK,CT,ECO,KCF,LOT,SCM和Struck。(Visual object tracking,include CREST,CSK,CT,ECO,KCF,LOT,SCM and Struck.)

副高五个指数的计算，可根据需要修改，数据需要提取，注意修改区域(the index of subtropical high)

60轨CAD断面图，严格按照国家标准作图，60轨CAD断面图(Cross-sectional drawing of 60-rail CAD)

说明：  频域滤波器器的一些相关实验和滤波器的实现（包括理想低通，Butterworth低通，高斯低通，理想高通，Butterworth高通，高斯高通滤波器）(Some related experiments of frequency-domain filter and Realization of filter (including ideal low-pass, Butterworth low-pass, Gauss low-pass, ideal high pass, Butterworth high pass, Gauss high pass filter))

说明：   图像编码源代码，包括：PCX， GIF，LZW算法和GIF数据压缩，JPEG，TGA，TIFF等(Image coding the source code, including: PCX, GIF, LZW and GIF data compression algorithm, JPEG, TGA, TIFF, etc.)

六次迭代使三角形三条线分形折叠，最后组成雪花(Six iterations make triangles become snow)

nca,近邻成分分析，距离度量学习里常用的。(nca)

DensePose用深度学习把2D图像坐标映射到3D人体表面上，再加上以每秒多帧的速度处理密集坐标，最后实现动态人物的精确定位和姿态估计。该技术集目标检测、姿态估计、目标部分/实例分割等多种计算机视觉任务于一身的一个综合问题。(DensePost maps 2D image coordinates to 3D human body surface by in-depth learning, and processes dense coordinates at the speed of multiple frames per second. Finally, it realizes precise positioning and attitude estimation of dynamic characters. This technology integrates many kinds of computer vision tasks, such as target detection, attitude estimation, target part/instance segmentation, etc.)

输出一个具有一定大小的双三角形，该三角形中间最小(Output of a certain size with a double triangle, the triangle between the minimum)

说明：  张正友标定方法的代码，已经包含了优化等情况，直接输入变可获得(calibration method code, Optimization has been included, direct input variable can be obtained)
