Class BackgroundSubtractor

java.lang.Object
  org.opencv.core.Algorithm
      org.opencv.video.BackgroundSubtractor

Direct Known Subclasses:

BackgroundSubtractorMOG

public class BackgroundSubtractor
extends Algorithm

Base class for background/foreground segmentation.

class BackgroundSubtractor : public Algorithm

// C++ code:

public:

virtual ~BackgroundSubtractor();

virtual void operator()(InputArray image, OutputArray fgmask, double learningRate=0);

virtual void getBackgroundImage(OutputArray backgroundImage) const;

};

The class is only used to define the common interface for the whole family of background/foreground segmentation algorithms.
