As I always say, send the sample image(s) and describe what you need
exactly. Maybe you're looking in the wrong direction.

See "baseapi.h", functions
TesseractRect()
SetImage() (reportedly, Pix* variant is more likely to be supported)
SetRectangle()
Then
Recognize()
or Get*Text()
Since your images are binary, use 1 bit per pixel.
Having implemented this approach, you will get image passing work
extremely fast.

Can you provide example image file (TainingMontage.png)?

You certainly can use tessdll.dll of Tess 2.04. A 3.0x DLL is not yet
available.

I made some corrections and included the latest updates to the process
as outlined in the TrainingTesseract3 wiki. This will correctly build

files in the same folder: [lang].[fontname].exp[num].tif,

Hello people,
I'm develping a licence plate recognition system from long ago and I still
have to improve the use of Tesseract to make it usable.
My first concern is about speed:
After extracting the licence plate image, I get an image like this:
https://docs.google.com/leaf?id=0Bxk
Thanks for your reply.
In another case, I use tesseract to recognize Chinese characters.
Some Chinese character is recognized as other wrong Chinese character, though
they are very different in apperance.
The Chinese character has many(dense) strokes is the reason ?
In this case, detecting ROI is
what format is your image in? it is very much possible to pass the raw image
data to tesseract directly instead of saving it on the disk...

Infraview saved worked. Imagemagick doesnt' seem to work. We are thinking it
has to be something up with imagemagicks lzw compression.

Hi,
I'm reasonably new to tesseract and am trying to train it to recognise
hex characters from a dot matrix LED display. The characters are
clear and well spaced, but the box file generation always results in
"Empty page".
I'm using tesseract 3, installed from tesseract-ocr-setup-3.00.exe.

hi, all
My application will generate bunch of separate binarized characters
and I need to feed the ocr engine for each of them. It will be very
costly if save each of them on disk as a tiff file and then call
tesseract. Is there a by pass so that my application (C++) can
directly call ocr and pass
Sorry, you were not saying this, I mixed some stuff up when reading up on the
issue this morning, this was what I was referring to:
According irfanview, is compressed as - LZW tif file of 300 DPI What Quan

supported only u
Sriranga and Mike,
Support for uncompressed TIFFs only is not an issue for a long time!
It was only during the period when Tess used a home-brewed TIFF
input/output routines. Now Tesseract does support many TIFF variations
through the use of Leptonica.
Actually I don't use the image handling part

Hello,
I've recently integrated Tesseract in an iPhone project thanks to the
instructions provided here: https://github.com/nolanbrown/Tesseract-iPhone-Demo
Turns out that the OCR process seems to be a bit slow. Well, "slow" is
a relative thing, but I would be interested in knowing what are the
