说明：  基于boosted的粒子滤波，用于冰球的跟踪(Based on the boosted particle filter for tracking hockey)

说明：  采用自适应非局部降噪的算法对图像进行去噪处理，能够实现不同算法的降噪处理(Using adaptive non-local denoising algorithm to denoise image can achieve denoising processing of different algorithms.)

在MATLAB平台下，实现两幅图像的相关比较。(Under the MATLAB platform, two images are compared.)

能实现最小包围盒法方格划分，并利用中值进行点云精简(The minimum bounding box method can be implemented and the median value can be used to simplify the point cloud.)

说明：  python语言，三种阈值分割方式，简单阈值分割，自适应阈值分割，OTsu分割方式(Python language, three methods of image segmentation , simple threshold segmentation, adaptive threshold segmentation, OTsu segmentation)

说明：  此文件为非均匀B样条曲线反求控制点再插值为曲线(This file is a non-uniform B-spline curve. The control points are inverted and then interpolated into a curve)

词袋模型，非常好的参考，有详细说明，希望顺利使用。(The bag of words model, a very good reference, there are detailed instructions, hope to use smoothly.)
