Method Details
- updateBackground
  
  public abstract void updateBackground(T frame)
  
  Updates the background with new image information.
- updateBackground
  
  public void updateBackground(T frame, GrayU8 segment)
  
  Updates the background and segments it at the same time. In some implementations this can be significantly faster than doing it with separate function calls. Segmentation is performed using the model which it has prior to the update.
- segment
  
  public abstract void segment(T frame, GrayU8 segmented)
  
  Invoke to segment input image into background and foreground pixels. If 'segmented' isn't the correct size it will be resized.
  
  Parameters:
  
  frame - (input) current image
  
  segmented - (output) Segmented image. 0 = background, 1 = foreground/moving
