multiple python implementations for image dithering

image dithering - wikipedia definition:

Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Dither is routinely used in processing of both digital audio and video data.

# implementation:

 ## method 1:

  ```pip install PyDither```

  

  ```

      import cv2

      import Dither

      img = cv2.imread('images/img1.jpg', 0)						# read image

      out = Dither.dither(img, 'simple2D', resize=True)			# perform image dithering

      cv2.imshow('dithered image', out)

      cv2.waitKey(0)

  ```

  

  ## method 2:

   Run the file main.py

# Results:

# Theory:

this repository implements 3 different types of error diffusion based image dithering algorithms.
