I am trying to build this for F-droid.org. I built it normally before then when I tried to build it with F-droid (an ant frontend) there were no libsos in the result. So I tried again by copying the library repo into the main repo as follows:

Build Version:0.5.12,31,5ca566,subdir=android,srclibs=TessTwo@cbfa61eff0,prebuild=\ sed -i 's@\(android.library.reference.1=\).*@\1tess-two@' project.properties && \ cp -r $$TessTwo$$ . && $$NDK$$/ndk-build -C tess-two

(the copy command translates to cp -r TessTwo/tess-two .

The error is this which is strange as I can't find any obj/

jni/com_googlecode_tesseract_android/src/textord/tabfind.cpp:1456:1: fatal error: opening dependency file ./obj/local/armeabi-v7a/objs/tess/src/textord/tabfind.o.d: No such file or directory compilation terminated. make: *** [obj/local/armeabi-v7a/objs/tess/src/textord/tabfind.o] Error 1

I'm only chancing my arm and using a netbook at that, so I can't be trying everything. Any help would be appreciated.

Hi,

How can i train the tess-two to recgnize only numbers?

Thanks in advance.

i am getting the following error
please help

At row 253 and 256 of OcrInitAsyncTask.java, CaptureActivity.OSD_FILENAME_BASE should be changed to CaptureActivity.OSD_FILENAME. In the previous way untarring of OSD data file launches an exception becouse you cannot untar a file named "osd.traineddata.zip", you can for a file called "osd.traineddata.tar.zip" instead.
Bye!

The app works good in landscape mode, but I need portrait mode. It was easy to implement portrait mode for non continuous mode, rotating data in the onPreviewFrame method, but it doesn't work real time in the continuous mode, are there any solutions for that?

Your sample worked great for me but does it possible implements android.hardware.camera2 instead of using deprecated old camera api ? If so, how do i start from ? Thank You

I was trying to build the OCRTEST but the error has appear ..

Hi,
This is a great piece of work, congrats!

I'm trying to integrate OCR into my own app, does the OCR test app offer any Intents that can be used to push results to other activities?

Lots of thanks,
MO.

I used your demo in my app for ocr. Whenever it runs first time, it downloads some stuff from internet. Can we hardcode it in our app? and if not it is taking time in orientation and script detection. My phone hangs there and i need to run the app again saying "Network issues". But if network issues are there why it is not haulting when ocr downloads english langauge.

Please help me with this issue.

I'm successfully running ocr app to portrait mode and want to change the view of "ocr result text" (on the right side of the picture "mol! ... bla2") in VERTICAL. So, it will appear in the bottom of translation label.

But, after i change the "Linear Layout" number 2 "orientation" on capture.xml which is the setting of "result text" layout (see picture). The result text does not appear.

The result i want: (view from top to bottom):

 Image 

translation label
ocr result text
ocr result text translation

How do i solve this?

At first I thought the problem was that I didn't build my ndk, so I did that. And it still crashes.

the app does not work on portrait mode , the camera is keep rotating

I got this problem when trying to run it on my device.

Automatic Target Mode: using device 'HT1BGVZ05406'

Can you help me to solve this problem? is this because error opening trace file?

One thing that I noticed that this app is not working on devices with Kitkat OS like (4.4.2)

Debugging on different devices is fine like on 4.0,4.1,4.2,4.3,5.0,5.1 but on 4.4.x it force closes
DO i need to update my library or there is a serious problem ....

When I try to start the app, it just shows a dialog "Unfortunately, OCR Test has stopped." Logcat is empty.

This only happens with the version from F-droid.
If I install it from Google Play Store or compile it myself, it works fine.

My system is Android 4.4.2, API 19

When I am trying to execute the code in android studio to an external device i always get a error on liblept.so

LOGCAT:

GOT ABOVE ERROR WHILE EXPORT PROJECT

This apk works on 2.3.7 before I update my phone to ICS.

I created my own traineddata since i Can't combine it to the eng.traineddata. Is it possible for the app to use use two or more traineddata at the same time.

Hi,

I am using your project as base for mine, I was trying to access the color of pixels of the image taken but I realized that the image is black and white, and I didnt find exactly where I can change this option, I mean, intercept the process before the image is converted into black and white. I thought it was under PlanarYUVLuminanceSource.renderCroppedGreyscaleBitmap() but my attempt to change this part didnt work. Could you help me with this?

Thank you very much.

Can you please add a share menu to this wonderful app. This would make your app a way more useful.

@rmtheis I am facing this issue on running the app.

This is my directory structure. I am trying to run on android studio 2.0 windows 10 (64 bit) machine.

Hey rmtheis,

Thanks for your awesome prototype ocr app! I've been using it to figure out how to get tesseract working on android. I have a ee signal processing background, and I'm kind of new to android.

What are the changes needed using your source to switch to portrait mode? I'm sure you have lots of your own stuff to deal with, but if you have a minute I'd appreciate the help! How is it that the camera preview appears orthogonal to reality?

Thanks
Arjun

Hi,

Hi.
First I want to say a great thank to you because your project help alot for my work.
I followed your project to build my own ocr app. It work fine for English. But I'm a Vietnamese and I really want to make this app in Vietnamese. I found a package for Vietnamese language of tesseract but I have no idea how to use it. Can you give me a direction to do it?

Pulling the latest camera init code from ZXing should fix this.

I am using this android-ocr source code and i want to modify it to translate and show the meaning in realtime . Does anyone has any advice or an example doing this.

Running Galaxy S5 Lollipop.

I am not able to get the code running. I import it but it's all a mess since Gradle is used and I can't make it work even though I added the Gradle plugin.

Could you add an explanation on how propperly to add it to Eclipse ?
I am interested on the API to get the text from an image, so if you could tell me what part does that it would also solve my problem, as I want it for a Java project.

Thank you.

caught exception in translation request

i have entered the client id and client secret in translator bing.java and trying to run the application. it throws the above error.

please help me to fix this.

Hello,

First thanks for the code.
I am trying to scan the number from document and i want to change the capture UI, but i am not able to view it in graphical layout and change it.
I am using eclipse.

Please help me.
Thanks in advance.

I've got a Sony Xperia SP with Cyanogenmod 12 (Android 5.1.1).

Hi,
I am trying to run your OCR demo with following steps :

1. Downloaded ndk 64 bit and saved it in a directory and gave the path in environment variables.
2. Imported tess-two project in my workspace .
3. Run ndk-build command which is giving some compiling messages probably compiling the ndk. 4. Now i imported OCRTest demo and used tess-two as library in that demo . When i run the code i got following exception. Log cat details are as follows :

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/edu.sfsu.cs.orange.ocr-1/base.apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]]] couldn't find "liblept.so"
It is crashing on this line System.loadLibrary("lept");
I can find out that when i run ndk-build, a never ending compiling messages keep on coming and yes one more thing, this particular .so file is in tess-two/libs/armeabi folder. Now can you guide me further what is missing
In my eclipse project, in libs folder i have only three jar files google-api-translate-java-0.97.jar, jtar-2.1.jar and microsoft-translator-java-api-0.6-mod.jar.
These are few details how i worked so far on ocr, how to take it further from here? Please resolve the issue
Thanks,

I've the latest installed on my Moto Atrix and when set to continuous capture mode it clicks and then crashes the app. The only way to fix this is to uninstall/reinstall.

Good Evening , I really want to thank you for making this experimental app, the issue that I am facing this time is that I already made the app orientation and camera view to portrait but the problem is the detection box is always detecting texts by landscape orientation. any help?

Can I start CaptureActivity from an external app?
Like zxing barcode:
Intent i = new Intent("com.google.zxing.client.android.SCAN");
startActivityForResult(i, REQ_CODE);

and get the result in data.getStringExtra("SCAN_RESULT")

While trying for words or sentence the text extraction works perfect but when trying same with a paragraph the extraction doesnt works. Why is it happening. All the parameter remain the same except no of words.
