基于选定区域颜色信息的跟踪算法，通过鼠标选择区域，计算区域颜色特征，对物体进行跟踪-Based on the selected regions of color information in the tracking algorithm, through the mouse to select the area, calculation region color feature, object tracking

VS2012，opencv3.0的基于颜色特征的粒子滤波跟踪算法实现，代码比较直观，虽然效率较慢，但容易理解。可直接运行-particle filter in object tracking ,based on color feature vs2012+opencv3.0
