How I replicated an $86 million project in 57 lines of code
Tait Brown

It makes for a catchy headline to say your implementation is only 57 lines of code.

There are probably a couple thousand LoC in openalpr itself, not to mention its dependencies (Tesseract, OpenCV).

OpenALPR is doing the real work here; you’re just feeding it the data. Of course your code is going to be minimal.
