Description: This readme describes the Biased and Filtered Point Sampling algorithm.
Before running the code, please run "compile_MEX.m" in the "dependent_files" directory.
BFPS.m is the main file that draws samples. A demo can be run from Matlab with the following command:
>> BFPS(double(imread( im.jpg )), 2, 1, 1, 0, 1)
For faster density estimates in non-parametric image segmentation, the fast Gauss transform can be used in place of Matlab s ksdensity function.

MeanShift运动目标跟踪 matlab程序
1.截取跟踪目标矩阵rect
2.求取跟踪目标的加权直方图hist1
3.读取视频序列中的一帧， 先随机取一块与rect等大的矩形，计算加权直方图hist2。
4.计算两者比重函数，如果后者差距过大， 更新新的矩阵中心Y，进行迭代（MeanShift是一种变步长可以迅速接近概率密度峰值的方法），直至一定条件后停止。
这两种算法为处理图像跟踪的基本方法
