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.

output on console is:

p is expected result iterator result, but choice iterator output is null.

Hello,
I use pageIterator's boundingbox function like this:
int left,top,right,bottom;
left=0;top=0;right=0;bottom=0;
api.Recognize(NULL);

Hello,
i need to provide a pix(of a char) to tesseract and hope it recognizes.
To try if i achieve this i did some internal experiments.
writing these code lines

api.SetImage(pixa);
char *sonuc=api->GetUTF8Text();
printf("%s",sonuc);

Hello,
when i write "apple" into a file tesseract some times resolve it as "app
le".
Do i have the chance to specify some value in some where and make tesseract
resolve some letters as they are in the same word?
Thanks

I tried it too, but could not succeed to get choice iterations. I am going
to try exact solution by that topic's itarator. If i succeed, i am going to
write here too.

Hello,
I wrote this code:
tesseract::ResultIterator* ri=api.GetIterator();
Pix* pixa=(*ri).GetBinaryImage(tesseract::RIL_SYMBOL);
l_uint32 width=pixGetWidth(pixa);
l_uint32 wpl=pixGetWpl(pixa);
l_uint32 h=pixGetHeight
Or there is a way in tesseract, for example a method which is not protected?
One point; i am aware of existence of pageiterator::getimage but i do not
want to get a symbol, i want to get independent black clusters.
Thanks for any idea.

Hello,
I think my problem is related to this.
But a little different
for example in my image there is
"lt"
and tesseract recognizes this as "H".
i do not want tesseract to combine blobs, i want it recognize blobs
individually.
What should i do?

Hello,
I installed tesseract-ocr software on ubuntu linux by downloading from svn

Is there somebody have ever used ResultIterator?

There is a pageIteratorLevel property, i think i must pass all paragraph,

Hello,
I am trying to look at all the code to find something.
I saw a line:
Boxa* TessBaseAPI::GetRegions(Pixa** pixa) {
i searched in the doc's index.html file, but there is no class or structure
named Boxa and Pixa.

Hello,
I am simplifying my question.
What is the name of the class and method that returns blobs(i assume blob is
the shape of a letter or a word which consists of contigious black pixels)

Hello,
or can i get it as a image with a transparent background?
I think tesseract first detects the pixels of the letters, it gets the shape
of the different colored pixels on image while solving images.
I do not know if i am true,
but if i am;
i want to use tesseract to get the drawn shape's
priate results.
For the attached file, i want to get 4 letters "in testing step", it does
not matter if the first letter is "d" or "g" or "a".
But i get 6 letters "fcgbcd".
I can not understand it.

the last three chars are correct "bcd".
But for "a" it returns "fcg" , three chars.

Hello,
There is a file attached,
I must confess, i wrote it with mouse, but the data that is needed to be
solved is like this.
Because we are developing a white board application.
I tried to solve it with ocropus but it could not.
I can not install tesseract alone, if you say it can solve this pic,
CellWriter needs to be trained but i need a handwriting recognition which
can recognize many different writers. Do you know about CellWriter, can i
use it by training it with a universal data set so it can recognize
different writers without training for every writer?
Maybe it is not the correct pl
Then, i can not use it because i want to recognize freely written
handwritings.
Thanks for reply.
