How to remove noise from an image using pillow?

I am trying to de-noise an image that I've made in order to read the numbers on it using Tesseract. Noisy image. Is there any way to do so? I am kind of new to image manipulation.

Solution

from PIL import ImageFilter

im1 = im.filter(ImageFilter.BLUR)

im2 = im.filter(ImageFilter.MinFilter(3))
im3 = im.filter(ImageFilter.MinFilter)
