/// 
/// ## Parameters
/// * history: Length of the history.
/// * varThreshold: Threshold on the squared Mahalanobis distance between the pixel and the model
/// to decide whether a pixel is well described by the background model. This parameter does not
/// affect the background update.
/// * detectShadows: If true, the algorithm will detect shadows and mark them. It decreases the
/// speed a bit, so if you do not need this feature, set the parameter to false.
/// 
/// ## C++ default parameters
/// * history: 500
/// * var_threshold: 16
/// * detect_shadows: true
