.. py:function:: threshold(image: numpy.ndarray, method: str = None, otsu_threshold_multiplier: float = None, **kwargs: dict) -> float

   
   Thresholding for producing masks.

   :param method: Method to use for thresholding, currently supported methods are otsu (default), mean and minimum.
   :type method: str
   :param \*\*kwargs: Additional keyword arguments to pass to skimage methods.
   :type \*\*kwargs: dict

   :returns: Threshold of image using specified method.
   :rtype: float

.. py:function:: _get_threshold(method: str = 'otsu') -> collections.abc.Callable

   
   Creator component which determines which threshold method to use.

   :param method: Threshold method to use, currently supports otsu (default), mean, minimum, mean yen, and triangle.
   :type method: str

   :returns: Returns function appropriate for the required threshold method.
   :rtype: function

   :raises ValueError: Unsupported methods result in ValueError.
