When I was running tesseract 3.0.4, there was no problem.
I tried to install tesseract 4.0.0 in ubuntu 16.04 by building it from
source, but there was an issue.
I referenced

this
Does not work in Tesseract 4.

Hey all,
I have a requirement to process invoices and extract few data elements from
it (e.g. invoice number, date, customer name, total amount).
Incoming invoices are of different formats with relative positions of data
elements. E.g. invoice number may be on right or to the left etc.
How would

in short - using command line to convert a .tiff format to .txt file - no
loop or any custom solution used. Yes the first 30 lines have the same
location and I am specifying to OCR only my first page
you mentioned about usage of unz f
It is not clear for me what do you want to achieve - for me it looks it is
case for custom solution with using tesseract API (C, C++, Python, maybe
others).
If you are can use only tesseract executable and your "30 lines" have the
same location (or you know their location in advance), you can have
see inline comments.

Why? IMO OCR engines are running on binarized images see e.g.

Yes and as far as i know that requires different training than LSTM because
in current state tesseract doesnt support that

Check the API:
https://pypi.org/project/pytesseract/
There is an example under: Support for OpenCV image/NumPy array objects
You may also try different languages (I had different results just on
numbers).

When you refer to TIFF/BOX file training, do you mean manually creating
your own boxfiles from your own set of images?
Note that by default, lstmtraining does generate TIFF/BOX files from the
fonts that you specify it to train on. With a little bit of wrangling, you
can actually configure lstmtrai
What is the recommended format for opening and editing these kind of files?

You can have a look at ocrd-train
https://github.com/OCR-D/ocrd-train
You just have to prepare cropped tiff and txt files with the same name
containing a single line of text.
At the same time, if you already set up everything for the font based
training, I'd give it a try (time permitting): you
Im planning on training tesseract to recognise sensitive information (3
letter followed by numbers, the point is to find the 3 letters so in post
processing we can lock that document because it has sensitive information).
While sensitive information is high priority Accuracy is key too and

Thanks very much for the advice. The ocr-evaluation tools look particularly
useful

Is there a guide somewhere how to setup training like this? How to pair the
images and text, etc..? And thank you for the insight, it really is helpful.

Yes, generating text is faster and easier.
But the real extracted and cleaned text you are going to eventually
recognize is going to be different from this, more or less depending on a
lot of factors:
- how similar your training font actually is
- how good your cleanup will be (test this in advanc
Well you just repeated yourself and did not provide any new information.
Like i said im using latest so what am i doing wrong? Also im not working

Thanks for your reply.
lstm training using box/tiff files is NOT supported.
Use tesstrain.sh with a UTF8 training_text and fonts.
Maybe you are right.But I think using training_text will also generate
tiff/box files in /tmp folder,so I think using box/tiff files and

Hello,everyone:
I have trained a new lstm model in my project,but the result is
not so good as I expected. I notice that some characters often mistake in
my result.
I learned that add some rules in .unicharambigs can reduce the mistakes?
I extract the eng.traineddata and get the
