Removing borders from an image in Python

Question

Some videos have frames that have black strips like borders. I have to remove them from the frames. I came up with a crude solution:

import sys, cv2, numpy
i         


        

Answer 1

This problem was already solved in this answer.

In [1]: from PIL import Image, ImageChops

In [3]: im = Image.open('iI3ZE.jpg')

In [4]: def trim(im):
   ...:         bg = Image.new(im.mode, im.size, im.getpixel((0,0)))
   ...:         diff = ImageChops.difference(im, bg)
   ...:         diff = ImageChops.add(diff, diff, 2.0, -100)
   ...:         bbox = diff.getbbox()
   ...:         if bbox:
   ...:                 return im.crop(bbox)
   ...:

In [5]: trim(im).show()

I used Pillow instead of PIL:

pip install pillow
