Tested on Linux with WSL2
Requirements are opencv for C++ (Install it with your package manager).
Compile threshold.cc with the following command
g++ -O3 -std=c++11 threshold.cc `pkg-config --cflags --libs opencv4` -o threshold
Python requirements are easyocr, jellyfish, srt
To install python requirements navigate to code directory and run this command: pip install -r requirements.txt
If you encounter problems with installing PyTorch (a dependency of easyocr) please visit the website here https://pytorch.org/get-started/locally/ and follow the given instructions to install PyTorch, and then run the command above once again.
Also ffmpeg must be installed
I'll probably convert the bash script to python and also may convert threshold to python but I'm worried about the performance hit. Had to use easyOCR instead of tesseract cause tesseract was just not as accurate.
Here's the link to the tesseract code if you can fix it. https://pastebin.com/7ja1NQeP. I assume it would be more performant.
