    • 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.
