Is there a way to remove ALL colors in the picture except white and subsequently replace the color white to black? Basically I want to remove the fuzz and I realised that only the color white is needed to decode the message.

Any help in python would be appreciated!

Here is a simple solution using numpy and PIL:

from PIL import Image
import numpy as np

img = Image.open('pic.jpg')
data = np.array(img)

converted = np.where(data == 255, 0, 255)

img = Image.fromarray(converted.astype('uint8'))
img.save('new_pic.jpg')
