The software in question is the winning entry in a hackathon from 2020: https://github.com/DevrathIyer/ballotproof
Inside that repo they have a script called `generate.py` which generates ballot test data.
Look at it for yourself: https://github.com/DevrathIyer/ballotproof/blob/master/gener...
It's a ~100 line python script that generates some test data. The last commit on is as naive as "hope this works".
What a horrendously misleading title. It's just some kids making something with OpenCV to scan images. Ridiculous.
