Access to MOG2 parameters via algorithm interface in 2.4.2 version

edit

I have achieved to set fTau parameter by inheritance;

Declare a custom class

class BackgroundSubtractorMOG2Custom: public BackgroundSubtractorMOG2{
public:
    void setTau(float val){fTau = val;}
};

Then;

BackgroundSubtractorMOG2Custom bgmodel;
bgmodel.setTau(0.35);

This is a bug in OpenCV 2.4.2
