中文说明：这段程序可以作为粒子滤波算法MATLAB平台实现验证模板，对于粒子滤波算法针对不同应用环境都有指导性的意义，通过改变样本数量可以明显观察理解得出粒子滤波基本思想，不管是应用于图像处理或者视频目标跟踪都有很不错的参考价值，希望对于有需要的朋友能够提供帮助。
English Description：
This program can be used as a particle filter algorithm MATLAB platform validation template for particle filter algorithm based on different application environment, has a guiding meaning, by changing the sample number of observations can obviously understand that particle filter idea, whether it is applied to the image or video target tracking a very good reference value, hoping for to be able to help a friend in need.
