public class BackgroundSubtractorMOG2
extends BackgroundSubtractorMOG2

\brief Gaussian Mixture-based Background/Foreground Segmentation Algorithm.

The class discriminates between foreground and background pixels by building and maintaining a model of the background. Any pixel which does not fit this model is then deemed to be foreground. The class implements algorithm described in \cite Zivkovic2004 .
