中文说明：国外大牛Mean Shift代码，思路比较清晰meanshift算法思想其实很简单：利用概率密度的梯度爬升来寻找局部最优。它要做的就是输入一个在图像的范围，然后一直迭代（朝着重心迭代）直到满足你的要求为止。
English Description：
Daniel Mean Shift foreign code, clearer thinkingmeanshift algorithm is actually very simple idea: using probability density gradient climb to find local optima. It needs to do is enter in the range of an image, and has been an iterative (toward the center of gravity of the iteration) until you meet the requirement.
