Hehe - well I was referring to the major os OCR lib. supposedly have LSTM-stuff in the next major rev https://github.com/tesseract-ocr/tesseract/blob/master/READM...

What Hacker News says
9 sourcesIn my experience, tesserect 4 with LSTM is far more accurate in recognizing characters. It was not there in 2015, so the post would probably need an update or a follow up.

In OCR and Medieval Manuscripts: Establishing a Baseline (2015)Oh, thanks. I had taken a looked at the number of commits which didn't have many after the last release so I thought it hadn't been merged yet.

In Creating a Modern OCR Pipeline Using Computer Vision and Deep LearningAbbyy has had that ability for a longer period of time so it may be more accurate, but this is something tesseract supports[1]. In fact I'd say most OCR systems support it with varying degrees of accuracy.

In Creating a Modern OCR Pipeline Using Computer Vision and Deep LearningI wonder how hard it would be to run a couple pages of dense print (though in a monospaced and consistent format) through an OCR system.
I might play with Tesseract[1] this weekend and see if this is even a feasible idea. If so, it makes the paper key storage a lot more palatable.

In Strategies for offline PGP key storageIf you plan on using tesseract definitely try out their 4.0 beta, which uses LSTMs.

In Using Tesseract OCR with PythonIn my experience Tesseract improves massively if you can identify the font the text is written in and prepare a custom trained dataset for it to use. See https://github.com/tesseract-ocr/tesseract/wiki/TrainingTess...
