Tess-two OCR not working

Question

im trying to get text from an image using tess-two on android.

But its giving me a really bad result

01-16 12:00:25.339: I/Tesseract(native)(29038): Initialized Tesseract API with language=spa

and like 30 seconds later it shows this as result string:

of course thats not correct, im using this photo:

i have tried it a lot of times, always similar result.

What can be wrong, this is my code using tess-two

    TessBaseAPI baseApi = new TessBaseAPI();
    baseApi.init("/mnt/sdcard/external_sd/tess/", "spa",TessBaseAPI.OEM_TESSERACT_ONLY);
    baseApi.setImage(bitmap);
    String recognizedText = baseApi.getUTF8Text();
    Log.d("Texto leido", "texto: "+recognizedText);
    baseApi.end();

and this is how i get bitmap from file

    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inPreferredConfig = Bitmap.Config.ARGB_8888;
    Bitmap bitmap = BitmapFactory.decodeFile(photopath.getAbsolutePath(), options);

im using that bitmap on a imageview and it seems correct, so i cant find why its working that bad.

Any idea?

Answer 1

Here change the language code for image text language.

eg: if you want English language text recognition, then use 'eng', or Spanish language for 'spa'

1)

   TessBaseAPI baseApi = new TessBaseAPI();
        baseApi.init("/mnt/sdcard/external_sd/tess/", "eng");
        baseApi.setImage(bitmap);
        String recognizedText = baseApi.getUTF8Text();
        Log.d("Texto leido", "texto: "+recognizedText);
        baseApi.end();

2)Download language package files from Download here you must download osd.traineddata.zip file and tesseract-ocr-3.01.eng.tar.zip(here eng for English, spa for Spanish.. etc) files paste into assets folder.

3)before set bitmap convert into gray scale image bitmap
