ABBYY recognizing business card work but photo fails


When I recognize text from the ABBYY business card it works. When I try it with a photo I took it failed. It does works on the demo from ABBYY so it's not my hardware.

Does anyone know why this is?

Code I use to take a photo:

            Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);  
            startActivityForResult(intent, REQUESTCODE_PHOTO);



    if(requestCode == REQUESTCODE_PHOTO){
        if( resultCode == Activity.RESULT_OK){
            RecognizerManager.recognizeText((Bitmap)data.getExtras().get("data"), this);


        }
    }


public static void recognizeText(final Bitmap bitmap, final RecognitionCallback listener){
        RecognitionConfiguration config = new RecognitionConfiguration();
        config.setRecognitionLanguages(Engine.getInstance().getLanguagesAvailableForOcr());
        config.setRecognitionMode(RecognitionMode.FULL);
        config.setImageProcessingOptions(RecognitionConfiguration.ImageProcessingOptions.FIND_ALL_TEXT);
        RecognitionManager recManager = Engine.getInstance().getRecognitionManager(config);
        try {
            Object o = recManager.recognizeText(bitmap, listener);
            Log.i("RESULT!", o.toString());
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (RecognitionFailedException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Solution

  • I got it to work using this following code.

    Photo taking in my RecognizeActivy:

                final File photo = new File( Environment.getExternalStorageDirectory(), genPhotoFileName() );
                RecognizeActivity.this.imageUri = Uri.fromFile( photo );
                Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE)
                    .putExtra( MediaStore.EXTRA_OUTPUT, imageUri );  
                startActivityForResult(intent, REQUESTCODE_PHOTO);
    
    @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            if(requestCode == REQUESTCODE_PHOTO){
                if( resultCode == Activity.RESULT_OK){
                    if(this.imageUri != null){      
                        try{
                            final AssetFileDescriptor assetFileDescriptor =
                                getApplicationContext().getContentResolver().openAssetFileDescriptor(this.imageUri, "r" );
                            long imageFileSize = assetFileDescriptor.getLength();
                            if( imageFileSize == AssetFileDescriptor.UNKNOWN_LENGTH ) {
                                throw new IOException( "UNKNOWN_LENGTH" );
                            }
                            InputStream is = assetFileDescriptor.createInputStream();
                            byte[] imageData = new byte[(int) imageFileSize];
                            is.read( imageData );
                            if(this.bitmap != null){
                                this.bitmap.recycle();
                                this.bitmap = null;
                                System.gc();
                            }
                            this.bitmap = BitmapFactory.decodeByteArray( imageData, 0, (int) imageFileSize, new Options() );
                            RecognizerManager.recognizeText(this.bitmap, this);
                        } catch(Exception e){
                            e.printStackTrace();
                        }
                    } else{
                        Log.e("ERROR", "img = null");
                    }
                }
            }
        }
    

    I'm recycling the bitmap because if I don't I get an OutOfMemory Exception after taking a few photo's.

    Photo processing:

    public static void recognizeText(final Bitmap bitmap, final RecognitionCallback progressListener){
        final RecognitionConfiguration config = new RecognitionConfiguration();
    
        config.setImageResolution(0);
        config.setImageProcessingOptions( RecognitionConfiguration.ImageProcessingOptions.PROHIBIT_VERTICAL_CJK_TEXT);
        for(RecognitionLanguage e : Engine.getInstance().getLanguagesAvailableForOcr()){
            if(e.equals(RecognitionLanguage.English) || e.equals(RecognitionLanguage.Dutch)){
                final Set<RecognitionLanguage> languages = EnumSet.noneOf( RecognitionLanguage.class );
                languages.add(e);
                config.setRecognitionLanguages(languages);
            }
        }
    
        RecognitionManager recManager = Engine.getInstance().getRecognitionManager(config);
        try {
            Object o = recManager.recognizeText(bitmap, progressListener);
            Log.i("RESULT!", o.toString());
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (RecognitionFailedException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
