      • apply

        public void apply​(Mat image,
                  Mat fgmask,
                  double learningRate)
        Description copied from class: BackgroundSubtractor
        Computes a foreground mask.
        Overrides:
        apply in class BackgroundSubtractor
        Parameters:
        image - Next video frame.
        fgmask - The output foreground mask as an 8-bit binary image.
        learningRate - The value between 0 and 1 that indicates how fast the background model is learnt. Negative parameter value makes the algorithm to use some automatically chosen learning rate. 0 means that the background model is not updated at all, 1 means that the background model is completely reinitialized from the last frame.

      • getBackgroundImage

        public void getBackgroundImage​(Mat backgroundImage)
        Description copied from class: BackgroundSubtractor
        Computes a background image.
        Overrides:
        getBackgroundImage in class BackgroundSubtractor
        Parameters:
        backgroundImage - The output background image. Note: Sometimes the background image can be very blurry, as it contain the average background statistics.
