binarize
==========================================

.. py:function:: petpal.preproc.segmentation_tools.binarize(input_image_numpy: numpy.ndarray, out_val: float = 1)

   Convert a segmentation image array into a mask by setting nonzero values
   to a uniform output value, typically one.

   :param input_image_numpy: Input image to be binarized to zero and
                             another value.
   :type input_image_numpy: np.ndarray
   :param out_val: Uniform value output image is set to.
   :type out_val: float

   :returns: *bin_mask (np.ndarray)* --

             Image array of same shape as input, with values
                 only zero and ``out_val``.
