tess-two's Issues

App crashed on nativeGetUTF8Text with eng.traineddata

My android app crashed without any exception on nativeGetUTF8Text(); on this picture:
http://img824.imageshack.us/img824/889/imgwords20130306171620t.jpg
but only with eng.traineddata, with eg. ces.traineddata it's working good.
(on others working eng too)
Don't know how to post you any log from native, and in LogCat is anything.

Library lept not found

I am using Eclipse IDE and Windows XP

I imported tess-two library project in Eclipse IDE and then I imported GautamGupta-Simple-Android-OCR-8a4d86d project. When I run it then it gives following runtime exception after photo taken from camera and my application crashed:

FATAL EXCEPTION: main

Please give me the needed steps to make project working successfully.

Could not find tess-two.apk!

    <uses-library android:name="android.test.runner" />
</application>

jni/com_googlecode_tesseract_android/src/textord/bbgrid.h:44:24: fatal error: ext/hash_set: No such file or directory

this error can not solve by me ...please give me solution regarding this.. urgent

Some methods have a bad delay time, such as meanConfidence,wordConfidences,getUTF8Text

I use the trained data from tessarect.I don't know why these methods need spent so much time.
Sometimes, the delay time is up to 2s.
The following is the way I ues it:
baseApi = new TessBaseAPI();
baseApi.init(FileManagerTool.getSystemPath(),CommonConstant.OCR_LANGUAGE);
baseApi.setImage(bitmap);
baseApi.meanConfidence();
ResultIterator resultIterator = baseApi.getResultIterator();
resultIterator.begin();

if I do not call meanConfidence or wordConfidences, the variable resultIterator will be null.
Could you tell us how to use the api?
Plealse give us some demos!
Thx,a lot.

init() crashes when used with custom training file

Whenever I try to initialize a tessbaseAPI with a custom language file (for an MICR font), it crashes with a SIGSEGV. I am able to init with other language files (I have tried english and swedish). The mcr.traineddata file works fine with other builds of tesseract (an iphone compile I found and tesseract installed locally on my machine). Any thoughts?

Has anyone tried the multi-language support featured in tesseract 3.02?

I tried the new multi-language feature in tesseract 3.02 but it doesn't seem to work.

For example, the image contains english and japanese words so during initialization I put in english + japanese combo:
_tesseract = new TessBaseAPI();
_tesseract.init(tesseractDatapath, "eng+jpn");
_tesseract.setImage(_imageToProcess);

The ocr result seems to be the same whether i use "eng" or "eng+jpn", english seems to dominate and the japanese words become random symbols. If i just use "jpn" the japanese words do get ocr'ed nicely into text but obviously the english words doesn't get ocr'ed well.

At this point I'm not sure if multi-language a false advertising on Google's side, or is the android version tess-two doesn't support multi-language?

Thanks in advance!

How to use EYES-TWO..?

hi,,,
i am able to use tess-two lib...but i m not getting any way in which or how i can use eyes-two or tess-two-test...
What is use of above ...?
How we can use in Android-OCR?
What is diffrent output we get thn tess-two..?
Please Explain guys.

Please update Tesseract Code base

Hi
Could you guys update to the current tesseract code base. i see the code is more than a year old :(

Thanks

Getting Fatal signal 11 error while capture line of numbers

I captured a pic with about 16 number no characters between them.
image size x = 500 , y = 100
decoded to bitmap with options.inSampleSize = 2;
the line divided into 3 words e.g. 32130 22121 21691

capturing an image with line of characters works without errors

32130 22121 21691 this give error.
asdfag grdad fgefgt this dont give error.

please if you have the app try capture this line and see yourself.

Tess-two performance comparing with original

I try to use this library since I want to implement OCR on my Android application. But, when I try it, the performance is worse than the original one. I have some image, it's very simple image with 1 sentence. I feed it to tess-two, it give me nothing. I feed it to original tesseract, it give very correct output. Then, I realize that traineddata used on tess-two is different, then I replace it from the original one. But, the result is still bad. Do tess-two using completely original engine or not? Anybody can give some suggestion?

The problem is that although it says "command not found", "arm-linux-androideabi-gcc" exists in the above path. Even when I run "arm-linux-androideabi-gcc" directly from /.../toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/ it gives the same error of "command not found"

I also added ./toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin to my PATH but still getting the same error. Even I tried different versions of ndk (7, 7b, 6b) still same error! seems to me the above gcc is meant for 32bit machines whereas my machine is "Linux 2.6.32-37-server x86_64". but I guess the ndk package should work for both 32 and 64bit. am I right? do I need to compile or build ndk before using it? I assume downloading and unpacking is all I have to do. right? how about sdk? I just downloaded and unpacked it at the same folder that I have my ndk. do I need to configure them to work with each other?

again when i removed tess-two library and doing uninstall from device and doing clean and build and run it's working fine no error is occurring, i want OCR functionality also in my project can anybody help me

Add Maven support pom.xml to project

Please add Maven pom.xml to project, as described in docs.

It's a pain to manually add it each time project is checked out - and prevents smooth automatic build.

Add support for Tesseract v3.02

Could not initialize Tesseract API with language=eng!

I am getting the above error message when I try to use tess-two in my Android application. I am able use the Simple-Android-OCR application and I have used some of the code from it in my own application. This is where I try to initialize the API:

TessBaseAPI baseApi = new TessBaseAPI();
baseApi.setDebug(true);
baseApi.init(path.getAbsolutePath(), lang);

Here are the variables used:

public static File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
public static final String lang = "eng";

I don't know why I am getting this error and I don't know how to go about fixing it. I have done some searches but I didn't turn up anything useful. I did look at some of the source code and I saw where this error is printed, but I couldn't find the api.Init(c_dir, c_lang) method that it refers to. I would appreciate any help in tracking this error down.

UnsatisfiedLinkError

I am getting this error:

03-09 21:49:57.368: E/AndroidRuntime(27702): java.lang.UnsatisfiedLinkError: Couldn't load lept from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.datumdroid.android.ocr.simple-2.apk"],nativeLibraryDirectories=[/data/app-lib/com.datumdroid.android.ocr.simple-2, /vendor/lib, /system/lib]]]: findLibrary returned null

This happens here:

03-09 21:49:57.368: E/AndroidRuntime(27702):    at com.datumdroid.android.ocr.simple.SimpleAndroidOCRActivity.onPhotoTaken(SimpleAndroidOCRActivity.java:211)

Which is this code:

TessBaseAPI baseApi = new TessBaseAPI();

From previous issues, they have said to make sure the build target is the same in the library as the project, but it is, as seen in these screenshots:

ndk-build problems

While we reference tess-two project to Android-simple-ocr app it raise unsatisfiedLinkError and says tess library gives null value.
i am build tess-two on ndk-8rb but it only generated the lept.so file not tess.so
how can i build tess so that the problem could solve
need help please

Will this build on 64bit Ubuntu (11.04)?

Or does it require 32bit?

Thanks.

user_patterns_suffix

Hi,
I would like to use the Tesseract feature described here in "CONFIG FILES AND AUGMENTING WITH USER DATA" : http://tesseract-ocr.googlecode.com/svn-history/r719/trunk/doc/tesseract.1.html

I need to specify a regex to match the recognition of a particular set of words.
In the doc they said that this can be done setting the variable "user_patterns_suffix" that takes as value the name of a file "user-patterns" where I need to put the regex.
I created a config file and put it in configs/ dir, then I loaded it with the ReadConfigFile() method of tess-two API.
This doesn't seem to work as expected.
I'm sure that the config file is correctly loaded because if I try to set in the file the "tessedit_char_whitelist" property, this works as expected.
So I think that the problem is in the "user_patterns_suffix".

Any idea?
Is there any alternative tess-two API method to limit the recognition of Tesseract to a set of words given a regex?

Thanks in advance for your help

text to png

I want to know if there is any method that I can use to convert/save the OCR-ed text into png format?
In my project I want to save the ocr-ed text so that I can use it for AR purpose.

Tesseract not building

Hi.. I am trying to build ndk. I am working on Windows 7 64-bit version. And ndk r7c. I am able to build Leptonia files but not Tesseract. Please help me with the issue.

WriteFile don't work as expected

Hi all,

I'm tring to create a OCR program using your code, but I'm having a lot of unexpected trouble and decided to create a JUnit test file to validate the class com.googlecode.leptonica.android.WriteFile.

The result of the tests follow below:

. The two writeBytes8 methods creates a invalid file format with 4.9Mb. I tried to open the file using Gimp 2.6 (attached image) but received a error dialog;
. The method writeFiles throw a RuntimeException with the message "writeFiles() is not currently supported". It is ok to me, because if the API say do not use, is supposed to don't use;
. The method writeMem always return null;
. The two methods writeImpliedFormat return true - that means success - but the files don't exist anywhere;
. The only method that works is the writeBitmap method.

The image used for test was taken from the camera and is a valid image.

Merge September 2012 changes from tesseract-android-tools

Apparently they event added in revision f4c034948666 APIs for GetRegions and GetWords.

I don't know if that brings forks closer or complicates the merge.
