Finding Differences in Images with Python and Pillow
Finding Differences in Images with Python and Pillow
May 20, 2025
Mike’s article about using Pillow to find differences in images.
In his example, you could output the difference using a simple function:
from PIL import Image, ImageChops
def diff(image_path_one, image_path_two, output_path):
image_one = Image.open(image_path_one)
image_two = Image.open(image_path_two)
image_three = ImageChops.difference(image_one, image_two)
image_three.save(output_path)
if __name__ = "__main__":
diff("yellow_butterfly.jpg","watermarked_butterfly.jpg")I can see how this could be useful to do a compare of a given picture like what Mike did or take a image of a chart and compare the differences as well.
