Coloring a B&W photo

I had seen a few people using AI to colorize old photos. It somehow takes known parts of a photo to figure out the colors. I think it works like this. If there are trees in the photo it knows those are green and from there can figure out the rest of the photo.

So I tried it on a photo I knew what the colors should be. In this pic the loco should be yellow and the cars red:







The program is called DeOldify:

Don't let Ted Turner know about this. He'll want to colorize the black and white parts of Wizard of Oz...

Already been done unless of course that was the sarcasm font.   :D

Well part of that movie is supposed to be in B+W. If you search YouTube for DeOldify you can see a few war movies that have been converted.

I ran a few photos through it.. and unless it has wide range of 'known' colors to assume, it has a hard time rendering colors.

It would be nice to have an eye dropper so we could tell it known colors.
For example.. It doesn't know Brown and Orange..

How to setup DeOldify
For those looking to try this themselves, here is a short tutorial on how to get things setup.
First, cd into the directory you would like to place DeOldify, then clone it:
git clone https://github.com/jantic/DeOldify.git DeOldify
Now cd into the newly created DeOldify directory and create a new “models” directory for your pre-trained weights:
cd DeOldify
mkdir models
You can now download the pre-trained weights through the command line:
wget https://www.dropbox.com/s/zkehq1uwahhbc2o/ColorizeArtistic_gen.pth?dl=0 -O ./models/ColorizeArtistic_gen.pth
If you don’t have wget, you can find links to manually download these pre-trained weights in the DeOldify README.
We also need to install dependencies:
pip install -r requirements.txt
Once the dependencies are installed, open the project in a Jupyter Notebook:
jupyter notebook
At this point, you should be able to open the ImageColorizer.ipynb file and continue from there. I hope this helped! Happy colorizing!

Those look like a bunch or Unix of CP/M commands.  I'm sure one of our many resident computer geeks can figure it out.  I'm a bit too rusty at this time.

Looks like Unix (Linux)  shell commands to me.
