前景检测算法（一）--综述  

前景检测的函数（Improved Background-Foreground Segmentation Methods），在2.4和3.3之间的变化。

在OpenCV 2.4里，有下面3个方法：
BackgroundSubtractorGMG()
This class implements an algorithm described in "Visual Tracking of Human Visitors under Variable-Lighting Conditions for a Responsive Audio Art Installation,"

BackgroundSubtractorMOG()
Gaussian Mixture-based Backbround/Foreground Segmentation Algorithm

BackgroundSubtractorMOG2()
"Improved adaptive Gausian mixture model for background subtraction


在opencv 3.3里，cnt()替代了mog2()：
BackgroundSubtractorCNT()
Background subtraction based on counting.
About as fast as MOG2 on a high end system. More than twice faster than MOG2 on cheap hardware


BackgroundSubtractorGMG()
This class implements an algorithm described in "Visual Tracking of Human Visitors under Variable-Lighting Conditions for a Responsive Audio Art Installation,"

BackgroundSubtractorMOG()
