This code is intended for an educational source to learn from and understand how Optical Charector Recognition (OCR) works.
I am not responsiple if you use this code for malicious purposes; This is not my intent in sharing it.

This code is very poor in effeciency; I created this as one of my first projects and haven't touched it in many months.
It still has lots of work to be done to make it a full "application". When I stopped this projected it was still a work in progress
and in its demo phase of development.

I have decided to make the code open source, so other may learn and improve it! If you improve my code please show me what you make (I'd love to see)!
I'd love to contact you on Discord preferably!
Discord username (may change): cyborg elf#7462 or Cyborg Elf#7462
Preferably you will join my coding Disord with lots of active users!: https://discord.gg/kDUHPVD

Here is a video of me doing a demo of the project: https://www.youtube.com/watch?v=H1d8a3lrSyk&index=12&t=0s&list=PLzBukBmD3GxsxNv2AFV8Ik9kj50CTKEW-
