tesseract.exe has stopped working on win2008 r2

[moos3]

I have been trying to get the latest version thats available for down
to work on windows 2008 server r2. The moment it goes to process the
file instant Has stopped working message on the screen. I was
wondering if any could build a new windows release or know how to fix
this issue ?



Thanks.

[Sriranga(78yrsold)]

which version tesseract-ocr you have downloaded for windows2008. For me latest version r578(released today) works fine for me in WinXP. I hope it must work for  windows 2008 server 2 - which I am not sure of it- since I don't have 2008windows.
Cheers.

Hi,

tesseract is command line tool. Item i windows menu is more or less just for testing purpose (it will not be present in next version of tesseract installer).

If you need gui have a look on Vietocr, PDF OCR X, lector etc.

Its erroring when I run it from the command line. doing like tesseract c:\image.tif c:\output.txt causes error once starting to process the image.

The following test command causes a "tesseract.exe has stopped
working." error:

"C:\Program Files (x86)\Tesseract-OCR\tesseract.exe" "C:/www/test/
wwwdocs/files/ea1/ea1064bb1fdb449c28f97fa31b8e3ea6.tif"
"C:/www/test/wwwdocs/files/ea1/ea1064bb1fdb449c28f97fa31b8e3ea6.txt"

Ideas on how to get this working ?

[Sriranga(78yrsold)]

Better to upload tif file for testing, if it is in English.

[Dmitri Silaev]

I'd say better upload a screenshot with the error message, the image file, your traineddata and command line you use.

Dmitri

[Lutz, Michael]

Just what I thought, have you check that the “tesseract.exe” is in the same folder as the “tessdata” folder?

I could provide an exe built on win7 32bit system, but I am not sure how to, since I think google blocks *.exe extension. Is it enough to rename the extension?

Here is the screenshot and the tif file. Dmitri if you rename the .exe that should work. I'm trying to get the traning data up.

[Lutz, Michael]

Hi,

I just ran your tif file, I get no results, it must have something to do with the size of the image. If I try to run a portion of tiff something smaller than 1000x1000 then I get results.

Can somebody explain why a tif size (2480x3508 @ 8BPP) is not processed?

Mike

[Dmitri Silaev]

You didn't attach the .exe and the screenshot, or don't I understand anything?

To pass the obtrusive Gmail's security checks, you can zip the .exe
with password protection (give us the password). Or you can place the
.exe into two nested folders and change its extension, then zip and
send.

Your .tif looks okay, though.

Warm regards,

The image appears to have been heavily compressed. OCR the whole image
did not yield anything. Doing it blockwise, I got some results but not
very accurate:

[Sriranga(78yrsold)]

According irfanview, is compressed as - LZW tif file of 300 DPI   What Quan says is correct  image is heavily compressed tif one. Tesseract-OCR is supported only uncompressed tif file only from my experience.

[zdenko podobny]

convert it to png - you got smaller picture with the same quality and tesseract should process it without problem.

This is not tesseract but leptonica issue (library used for image handling). When I run it on linux I got error message comming from leptonica (1.67 -> I did not try 1.68 on linux yet):
Error in pixReadFromTiffStream: spp not in set {1,3,4}
Error in pixReadStreamTiff: pix not read
Error in pixReadTiff: pix not read

On Windows leptonica "release version" library did not show error/warning messages because of compile option "NO_CONSOLE_IO" (see http://code.google.com/p/leptonica/issues/detail?id=42).

It looks like leptonica did not support lzw compression for tiff ( see http://www.leptonica.com/source/README.html  "9. Image I/O" - lzw is mentioned in png and gif section, but not with tif). I change tif compression from lzw to zip (BTW: this will cause smaller image), tesseract will produce ouput (on XP SP3).

Guys, I still can't understand what the error is produced by
Tesseract. Let's wait for the error screenshot. Or did you understand
everything already? Richard says he's got an error message...

I get same warnings on with Leptonica v1.68 on Windows XP SP3.

Incorrect. At least on Windows I build libtiff with "LZW_SUPPORT = 1"
in my nmake.opt file.

You can see the actual problem by looking at
http://tpgit.github.com/Leptonica/tiffio_8c_source.html#l00274, where
Leptonica gets the TIFFTAG_SAMPLESPERPIXEL. It allows 1, 3, or 4 but
not 2 as this image contains.

Tree different users with working tesseract-ocr have problem with this input. Isn't it sufficient for you? Yes there could be other issues related to Windows 7 (because official build was done on 32bit Windows XP), but without solving "input issue" other investigation will be unnecessary difficult...

Interesting. How did get this information? I tried:

• identify (imagemagick): TIFF 2480x3508 2480x3508+0+0 8-bit Grayscale DirectClass 1.556MB
• infranview "says": Original colors: 65536   (16 BitsPerPixel); Current colors: 256   (8 BitsPerPixel); Number of unique colors: 41;

Thanks for clarifying this. As I mention It was just my guess based on my observation of README :-)

I used:

ACDSee and

AsTiffTagViewer
(http://www.awaresystems.be/imaging/tiff/astifftagviewer.html) The
results are a bit complicated but pretty sure this one tells you
EXACTLY what the tiff tags contains. "Whenever a customer reports your
software doesn't handle this or that particular TIFF, use
AsTiffTagViewer and discover why." :P It's the only tag viewer I know
of that correctly shows the ImageDescription tag for each page of a
multi-page tiff. Most image viewers seem to only show the first page's
ImageDescription.

And since you asked, I also ran the libtiff 3.9.4's tiffinfo.exe to get:

TIFF Directory at offset 0x174e32 (1527346)
Image Width: 2480 Image Length: 3508
Resolution: 300, 300 (unitless)
Bits/Sample: 8
Compression Scheme: LZW
Photometric Interpretation: min-is-black
Extra Samples: 1<unassoc-alpha>
FillOrder: msb-to-lsb
Orientation: row 0 top, col 0 lhs
Samples/Pixel: 2
Rows/Strip: 1
Planar Configuration: single image plane
Page Number: 0-1
DocumentName:
C:/www/test/wwwdocs/files/ea1/ea1064bb1fdb449c28f97fa31b8e3ea6.tif
Predictor: horizontal differencing 2 (0x2)

Looks to me like some programs just look at Bits/Sample and forget to
also take into account Samples/Pixel?

Incorrect:

1. image support is task of leptonica, so list of supported format can be found of leptonica web and source code. I think we really need to distinguish this, because with upgrading of leptonica there could be support for new format without changing a line in tesseract code.
2. I guessed that leptonica has problem with tiff with "lzw compression". When I created tiff with "zip compression" it worked (there are also other compression algorithms available in tiff: Packbits, G4, G3,...). I never said that leptonica (tesseract) support only uncompressed tiff. I am sorry if I was not clear about this.
3. As TP corrected me: problem is not in LZW compression, but in "Samples per Pixel". Leptonica support 1, 3, 4. Input image used (unsupported) 2. To "solve" this just open input file in InfranView and save it as tiff with lzw compression. It will change "Samples/Pixel" to 1 automatically ;-)

 Zdenko

I attached the image as an uncompressed TIF file, see uncompressed.zip, this image is processed by tesseract without any problems.
Also attached is a tesseract.zip, which should unpack a tesseract.executable, just rename it to tesseract.exe if it went through, it is a release static build using Win7 and WinSDK 7.1 if anyone still wants it.

Mike

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 of Tesseract, so I'm
rather interested in investigation of Tesseract's errors, not
Leptonica's.

Warm regards,
Dmitri Silaev

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

[tarık Kaya]

i changed the tesseract.exe and it worked. tesseract version 3.2.0.0 .
