.. py:function:: otsu_threshold(image: PIL.Image) -> PIL.Image

   Applies Otsu's thresholding method to a grayscale image.

   Parameters:
   image (PIL.Image.Image): A grayscale PIL image object.

   Returns:
   PIL.Image.Image: A binary image after applying Otsu's thresholding.

   Example:
   >>> from PIL import Image
   >>> import numpy as np
   >>> image_array = np.array(
   ...     [[0, 0, 0, 0], [255, 255, 255, 255], [0, 0, 0, 0], [255, 255, 255, 255]],
   ...     dtype=np.uint8
   ... )
   >>> image = Image.fromarray(image_array)
   >>> binary_image = otsu_threshold(image)
   >>> np.array(binary_image)
   array([[  0,   0,   0,   0],
          [255, 255, 255, 255],
          [  0,   0,   0,   0],
          [255, 255, 255, 255]], dtype=uint8)
