Pixelate Image With Pillow

Question

I am working on a project where I want to take a picture of a colored grid as an input (made with Lego bricks in this example) and return a much smaller modified picture.

Answer 1

Pixelator does the trick. It is a package based off or rr-s answer. It also has some added benefits for AI and ML applications.

In bash

pip install pixelator

in python

from pixelator import pixelator
palette = [
    (45,  50,  50),  #black
    (240, 68,  64),  #red
    (211, 223, 223), #white
    (160, 161, 67),  #green
    (233, 129, 76),  #orange
]

sensitivity_multiplier = 10

size = (4,4)

output=pixelator(
    in_path='./images/input.jpg',
    palette=palette,
    size=size,
    sensitivity_multiplier=sensitivity_multiplier
    )

output.resize_out_img().save_out_img(path='./images/output.jpg', overwrite=True)
