Image Processing with Pillow - a Python Code-Along

In this lesson, we'll focus on the Pillow Python library, also known as PIL.
I'll show you a few basic functions and useful tricks to manipulate each and every pixel on a given image.
By the end of this video, you'll know how mathematical operations affect images and you'll be comfortable with exploring Pillow further on your own!

Oh look.. it's my favorite python teacher.

This is a very helpful tutorial to understand the basics of Pillow. Thank you very much.

Hey, great video. Do you have any content that explains how to display multiple images from an array INSIDE of a GUI? I know how to place images individually as labels, and I know how to use PIL to open up a folder of images on my desktop separate from the GUI. I've gotten as far as adding those images to an array, but am stuck on how to actually pack each image into the GUI. I am only able to open them with .show(), which again opens them up on my desktop as if clicking on the image normally. Thanks.

Thank you, this video helped me with images processing. Great channel

Thank you for the erection; I mean explanation. Really helped my confinement time pass faster.

absolutely sublime & studentfriendly DIP lecture from a really good mentor .helped me to understand easily & quickly .would you like to make a video for me on 'haar transformation' miss?!

me: woah i didn't know a girl programmer existed
mariya: yes

Hi, new to your channel. Great work! I will definitely check out more of your videos.
Please explain to me why at 2:10 calling "O" displays the image. How come you don't have to use .show() ?
Thanks

[romirmathur]

Great lectures.... 👌Really enjoyed them

Hi Marjia, I tryied this code:

from PIL import Image
pics =
for i in pics:
pic = Image.open(i)
new_pic = pic.resize((300, 300))
new_pic.save(i)

It returned:
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated escape
What did I do wrong?

Hello, your video is good 👍, but can you zoom in, because there's a lot of white spaces and the code is very small for the mobile users, and thank you .

Você é brasileira reconheci pelo sotaque!

11:43 well it's _monochromic_ to be exact.

[chiranjeebroychowdhury]

Finally someone is talking about Pillow! I have done lots of image manipulation with MATLAB in my undergraduate course and I feel the Pillow library comes the closest to that. Nice one Mariya!
P.S. Love the Rolling Stones reference! *wink* *wink*
