Yes, can you explain PSM 8?
Is it something like PSM_AUTO, should i change pagesegmode to PSM_8?
In this mail group, i was advised to give tesseract characters one by one.
Thus i must learn how to make tesseract recognize alone chars in images.
Thanks in advance.

Hello,
First of all i want to confirm that i understand choice iterator right.
For example if i have a word on an image "scope",
choice iterator must give me something like "s" and maybe after Next(), "5".
for 3. letter "o" it maybe gives me "0", after Next() "O" and after Next()
"o".
Do i und
Tesseract won't handle the lines of the table, but you should be able
to remove them through image processing and construct a table from the
spaces (perhaps regular expressions would help there). If you post an
example image we might be able to help.

In the event these thoughts might prove useful to others...
While I've not yet proven this, I currently theorize that the
SetImage(raw) functionality does not correctly handle images where the
physical raster storage is longer (rounded to dword) than the logical
raster length.

I've downloaded, compiled, and tested tesseract 3.01 from the
commandline and would now like to begin testing using TessBaseAPI.
(note: build system is Windows MS vs2010 - using the provided .sln
file)
I think there is some basic configuration problem that I'm
missing...I'd sure appreciate a poin
What's PSM? Alternative spelling for PMS :-)?

The basic reason it helps Tesseract to repeat text is because
Tesseract makes an initial assumption what kind of letters it is
looking at: tall (digits, uppercase letters, tall lowercase) or
lowercase letters. Only after it makes that assumption / guess will it
try to match the letters against the

That is interesting. I'm recognizing espiration dates from medicines, and I
found convenient to repeat the date 3 or 4 times, it improves recognition.
Someone can explain the reason.

Hello,
i can't found anything about, how many letters/numbers an tif must
have, so that tesseract can find these.
For example I have an picture only with the number 3, but tesseract
don't detect this number. But if i put 3 3 3 3 in my picture tesseract
detect the numbers. So my Question is: What
Hello all,
I am trying to convert the TIF image to text using Tesseract OCR.
I try to convert with command line, but not all words are convert.
Can someone guide me on how to efficiently use Tesseract for the conversion
of image to text?
And another question, can someone explain me how to r
