Hello,
CMC-7 is totally a different font than E13B. It's only E13B around
myself. I've never seen CMC-7 in person.
I had about 100 sample checks and used a check reading machine, one of
those at banks. Thus they're in the same image quality and character
quality.
Although it's a small samp
thanks for your responses
@Timothy Snyder: I think I cannot do this in postprocesssing, as it is
possible that both spellings occur, but I have to differentiate them. Or
what did you do exactly?
@zdenop: Unfortunately it is not possible for me to send a longer text.
anyone else any ideas?

You say that both letters looks the same (same height too?) and that it is
not possible to do it in processing as both spellings are possible. How is
tesseract, or a human, supposed to tell them apart?
Can you please share a sample? Maybe using a smaller/bigger image is
enough. Or maybe the image
Try to invert the images.

@Lorenzo Blz: This is an example image. The output of my code is
"calibrations". The height of the letters is not the same. Of course it
cannot be recognized if there is only a "c", but in the context to the
other letters tesseract should be able to detect if it is a
Please provide more information (versions info, how you do OCR - seem like
you use some coding).
I just tried tesseract (tesseract 5.0.0-alpha-416-g408d6) command line with

I use Tesseract 3.02 leptonica-1.68. What do you mean with tessdata_best?
I'm new in this field and just know how to call tesseract with the given

I'm using this Python code:

I tried to upscale, downscale, with and without the white border and I
always get Calibrations. I even tried a few psm modes.

I am following https://github.com/tesseract-ocr/tesseract/issues/1453 for
tesseract 4.0 learning.
I am using macOS mojave.
All was good until i tried 'text2image --list_available_fonts
--fonts_dir=/Library/Fonts'.
o/p i get on this is '-bash: /usr/local/bin/text2image: No such file or
director
I have the same problem

Does /usr/local/bin/text2image exists? Did you
installed text2image/training tools?

You already send this to forum and I already replied. Did you read it?

You were both right - updating to version 5 fixed the problem more or less!
Only in one case there is still a problem with lower and upper case
letters, but for the other cases it's working now!

You received this message because you are subscribed to the Google Groups
"tesseract-ocr" group.
But therefore I get empty strings now, because it occurs a symbol that
tesseract does not know. I had this problem before as well, but could fix
it for whatever reason with config='--psm 7'. This doesn't work now
anymore... Do you have an idea for this as well? I don't need to detect the
symbol
I am using some other model for text detection, I get text boxes for each
line in the image(basically some time identity cards). Now i need to pass
them through the tesseract for recognition. Which psm mode do you think
will the higher accuracy between psm13 and psm7.

For the same image, I am using the tesseract to get the text output. But
apparently the output is bad on linux version (RHEL) than windows (Windows
10). I also made sure that all the installation dependencies and version
are same.
Kindly let me know how to deal with this.
Thanks

Do you really think that somebody can reproduce problem based on

I did not tried it, but if you have installed leptonica, you can install
tesseract from source, just adjust relevant part of cmake configuration.
AFAIK vcpkg uses cmake and ninja, so this this tutorial (last part) can
help you:
