Hi,
I am trying to run tesseract-ocr on invoices to detect user ID's, Invoice
numbers, tax codes etc. I think tesseract has not been trained on this kind
of data so i need to fine tune the network on my data. Now it will be a bit
difficult for me to get labelled data to fine tune tesseract as s
No, tesseract cannot be trained in an unsupervised manner, it needs ground
truth labels to train from scratch or fine-tune. Please provide a sample
image to test if possible.

Is there any way tesseract could be installed using pip for Ubuntu 16.04
systems and above?

pip is for distribution python modules and tesseract is c++ project, that
are distributed with other tools (depending on linux distribution) - on
Ubuntu it should be apt.

In that case, would it be possible to find a way to install tesseract via
apt on Ubuntu 16.04 systems?

I am not trying to train the whole model in an unsupervised way, I just
want to train the language model which act as the final layer of tesseract
to generate variable length sequence, this will act like a *pre-training*
step. Just like other language mode
Thank you, now is working (tesseract c:\Flaviu\imagine.png C:\Flaviu\output

Actually when You open out.txt file in Notepad it's not empty. There is an
arrow there. The same arrow appears in PyCharm output. Previously it was
empty.

Just a small note (in case someone will land on this thread): I recently
found out that PSM 7 and others work better than 13.

I tried opening the file with python and reading the contents. Pasting the

Let me know if this helps. Can anyone else confirm this?

Does tesseract support recognize multiple language in one document ? and
how would do that ?

Gimp is your friend:

If your programming, use KalikoImage library to replicate manual GIMP steps,
that’s easy.

Hi everyone,
I am trying to use Tesseract for single character recognizing and the
results are awful.
"h" is recognized as "n", "4" as "/i", "O" as "()";

Hello all,
During 2 weeks, I trained JPN_VERT little bit further.
I included heart symbols, which are commonly used in Japanese comic books.
Whenever I tried to OCR, the entire sentence got weird. So, I got around
the issue by training those symbols.
I also trained casual conversations more. The
Try to use psm 7 or 13 (SINGLE_LINE and RAW_LINE). In my case 7 works best.
I'm not 100% sure but it may be easier to recognize full words rather than
single characters. But I do not know if this is just a test or if this is
what you need to do.
The default oem mode (lstm) should be the best, but
Thank you for sharing.
It will be helpful if you add this info to the readme file in your github
repo also.
Please share the training options that you used, number of fonts,
iterations etc. It will be useful as reference .

Hi,
How can I develop a GUI Application with my traineddata files. I've trained
in LSTM and 3.05 and need to embed in a desktop application. How can I do
that??

1. If you have quality problem - it good to play with tesseract
executable instead of API ;-)
2. It is know that passing text (in your case just one letter) is not
best idea - please try to add small white border e.g. 10 px
3. Please set dpi for image after SetImage

Hi,
" Why the version is 4.0." What do you mean by that? In logs it states that
it's 3.04v. "Tesseract Open Source OCR Engine v3.04.01 with Leptonica".
The problem might be the fact that 4th version is using lstm files whereas
you have version 3.04 using box files instead. Try to check the version
Hi,
Typo: " Why the version is not 4.0.?

Robert is pointing you to right direction. Did you read the log you post
here?
" Tesseract Open Source OCR Engine v3.04.01 with Leptonica"
You are mixing tesseract versions so no surprise of problems.

Yes, in the log I see version "3.4v".
To install v4, I used the link "https://github.com/tesseract-ocr/tesseract";.
I thought it has tesseract v4, as the Readme file say "Source code for the
new LSTM based 4.0 version is available from the master branch on GitHub."
So, I did a git
