6 years ago Hi @techvedikasolutions,
unfortunately, we don't have those devices at the office, but we tested our SDK on few other devices with the code snippets that you have provided. We haven't noticed any performance issues. Maybe there is a problem in your implementation of the ImageListener, maybe you are performing some expensive operations there. Can you please share your implementation of the ImageListener with us? While we were testing the SDK, we used this ImageListener implementation from the documentation.
When you use setNumMsBeforeTimeout, you can get partial results. For example, if you set number of milliseconds before timeout to 2000ms, when first non empty result arrives (for example only first name is scanned), after 2000ms scanning will be finished and you will get the data which was scanned up to that time. Probably, that is happening when you are scanning the German driver's license.
Can you please send us the images of the documents that you are trying to scan to support@microblink.com.

Hi,I updated my blink sdk from 3.6.0 to 3.12.0.I tested my app in different devices(Moto e4-7.1.1V,HTC-6.0V,Asus-5.0.2V)Below are my observations(scanning performance issues) and code settings for corresponding recognizer settings.
1.mrtd documents scan with image listener(like common passport docs) scanning time is too long in 3.12.0 compared with 3.6.0 Code settings : MRTDRecognizerSettings mrtd = new MRTDRecognizerSettings(); mrtd.setShowFullDocument(true); mrtd.setAllowUnverifiedResults(true); scanIntent = buildIntent(new RecognizerSettings[]{mrtd}, ScanCard.class, null); 2.USDL barcode scan with image listener scanning time is too horrible in 3.12.0 Code settings: USDLRecognizerSettings usdl = new USDLRecognizerSettings(); usdl.setUncertainScanning(false); usdl.setNullQuietZoneAllowed(false); scanIntent = buildIntent(new RecognizerSettings[]{usdl}, ScanCard.class, null); 3.For German driving license(EUDL) : Scanned immediately but getting only first name(getting correct name) and last name(getting incorrect name) details from the results. Code settings: EUDLRecognizerSettings germanDl = new EUDLRecognizerSettings(EUDLCountry.EUDL_COUNTRY_GERMANY); germanDl.setShowFullDocument(true); scanIntent = buildIntent(new RecognizerSettings[]{germanDl}, ScanCard.class, null);
MainIntent Settings private Intent buildIntent(RecognizerSettings[] settArray, Class<?> target, Intent helpIntent) { final Intent intent = new Intent(this, target); intent.putExtra(ScanActivity.EXTRAS_BEEP_RESOURCE, R.raw.beep);
if (helpIntent != null) { intent.putExtra(ScanActivity.EXTRAS_HELP_INTENT, helpIntent); }
RecognitionSettings settings = new RecognitionSettings(); //IMAGE meta data settings MetadataSettings.ImageMetadataSettings ims = new MetadataSettings.ImageMetadataSettings();
ims.setDewarpedImageEnabled(true);
ims.setSuccessfulScanFrameEnabled(true); settings.setNumMsBeforeTimeout(2000); settings.setAllowMultipleScanResultsOnSingleImage(true); settings.setFrameQualityEstimationMode(RecognitionSettings.FrameQualityEstimationMode.ALWAYS_ON);
settings.setRecognizerSettingsArray(settArray); intent.putExtra(ScanActivity.EXTRAS_RECOGNITION_SETTINGS, settings); intent.putExtra(ScanActivity.EXTRAS_LICENSE_KEY, Config.LICENSE_KEY); intent.putExtra(ScanActivity.EXTRAS_SHOW_FOCUS_RECTANGLE, true); intent.putExtra(ScanActivity.EXTRAS_ALLOW_PINCH_TO_ZOOM, true); intent.putExtra(ScanCard.EXTRAS_SPLASH_SCREEN_LAYOUT_RESOURCE, R.layout.loding_screen); intent.putExtra(ScanCard.EXTRAS_IMAGE_LISTENER, new MyImageListener()); intent.putExtra(ScanCard.EXTRAS_IMAGE_METADATA_SETTINGS, ims); intent.putExtra(SegmentScanActivity.EXTRAS_SHOW_OCR_RESULT_MODE, (Parcelable) ShowOcrResultMode.ANIMATED_DOTS); return intent; }
In all devices the performance is same.Please check this and let me know if any code settings need to be change at my end.
Thanks in Advance.
