Mean Shift是一种最优的寻找概率密度极大值的梯度上升方法，利用核概率密度描述目标的特征可以应用于目标跟踪技术，本程序实例即是基于Mean Shift原理进行目标跟踪，搜索目标位置。-Mean Shift is to find an optimal increase in the gradient of the probability density maxima nuclear probability density describing the target feature target tracking technology can be applied to the instance of the program is based on the principle of Mean Shift target tracking, the location of the search target .
