tess-two (or Tesseract) crashing with large images about tess-two

[rmtheis]

Thanks. This is a useful test case.

Have you tried it on an AVD with a large amount of RAM installed? I'd be interested to know if that gives the same result.

Hi,
before writing to you, I got this error 3-4 times. Now I'm trying to reproduce it, but it's not really easy and I'm getting really strange behaviours.

The images I'm using now are really big (1840x3264 for example). I'm loading them with this code:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2;
bitmap = BitmapFactory.decodeFile(path, options);

I'm using a sample size of 2 to avoid application heap to exceed the size limit.
Here it is what I get with the last tests.

HTC Sensation XE (Android 4.0.3):
on this device I get the error reported when trying to recognize text on the really first image I provide to the application. After that tess-two works without problems on any image. Plus, I can reproduce the error often only with a specific image.

AVD 1GB RAM (Android 2.3.3):
on the emulator, tess-two and my application crashes with any image I give them. But the line "A/libc(15675): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1)" is not reported in LogCat. Everything crashes silently.

With Tesseract 3.01 no errors are reported in both cases.
I'm not really expert in debugging C/C++ code. I'm really sorry about that.
Some additional informations:

• I compiled tess-two under Archlinux
• I'm simply using the method getUTF8Text() on the images

Feel free to ask me for other tests. Cheers.

where to download Tesseracct 3.01 library for android ??

[rmtheis]

@Abol3z:

git clone git://github.com/rmtheis/tess-two tess
cd tess
git checkout 071820a324

thanks, I used your command in Git Bash,
but this error 10-11 11:13:15.727: A/libc(15675): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1) still appears in my code !!

Hi, so anyone got the answer for this issue? I'm trying to make an OCR application using tess-two and still stuck with this issue for a long time. I event don't know why it happened with some images, others is ok.
Thanks for help.

I'm having the same error.
I believe its a memory issue, but it only crashes with eng.traineddata. With other trained files, the same image is not crashing any more (ex: spa.traineddata).

Any solution found?

Thanks!

I had the exact same problem. After several hours I found, that I was using an older eng.traineddata file from Tesseract 3.00.
To solve the problem just download the latest eng.traineddata on github and replace :) - Hope that solves your problem too

Thanks! I'll give it a try!
