.. py:class:: Burkes(input_img, threshold: int)

   Burke's algorithm is using for converting grayscale image to black and white version
   Source: Source: https://en.wikipedia.org/wiki/Dither

   Note:
       * Best results are given with threshold= ~1/2 * max greyscale value.
       * This implementation get RGB image and converts it to greyscale in runtime.

      :classmethod:


      >>> Burkes.get_greyscale(3, 4, 5)
      4.185
      >>> Burkes.get_greyscale(0, 0, 0)
      0.0
      >>> Burkes.get_greyscale(255, 255, 255)
      255.0
