Core:

Massive improvements in performance and quality across all modules.
Document detection and crop
- Added capability to locate and recognize double page spread of the document in one image. There are passports, that have meaningful data not only on the data page, but also on the second page of the spread. To get the data from both pages in one go we have implemented this “Double page spread” mode. Disabled by default.
- Added capability of smart detection of the document by its recognition. Document can be in any orientation, flat or with perspective distortion, hold in the hands like a book, etc. This greatly improves success rate on mobile and service use cases. Can be enabled/disabled in process parameters. By default, enabled for processing of static images and disabled for processing series of images from camera on mobile.
- Optimized ID2 Visa stickers cropping from passport page.
Document type recognition
- Improved performance of document type recognition by multiple algorithm optimizations.
- Improved quality of document type recognition. Now document images with corrupted proportions, not fully visible in image, with high perspective distortion are correctly recognized in most possible cases.
- Improved recognition of documents with non-standard proportions.
- Improved algorithm of image resolution determination by using data from templates (laminated documents).
OCR
- Added scenario OcrFree for arbitrary text OCR, based on provided parameters. You can define field definition template using mask and recognize any data, not only on documents.
- Added support for Armenian alphabet (lcid 1067).
- Added support for Malta language (lcid 1082).
- Added bank cards recognition in specific scenario.
- Added recognition of registration stamp (address) in Russian Federation domestic passports.
- Added recognition of CCC/CTC codes for China / Hong Kong documents.
- Improved recognition of text with multiple languages in one field.
- Improved recognition of special symbols, like @, ≤, ≥, *, _, etc.
- All alphabets recognition is now based on neural networks (including Greek, Georgian, Azeri/Turkish).
- All NN were re-trained on significantly larger datasets to ensure better recognition accuracy.
- Improved recognition time.
- Document templates were revisited for each field to assure correctness and high recognition accuracy based on statistics.
- Perforated numbers OCR now available on all platforms (Ukraine domestic passport).
- Optimized serial OCR recognition mode from multiple frames, based on recognition probability and matching results between frames.
- Internal resource usage optimization that allowed to reduce memory impact and package size.
Text data parsing and validation
- Added content validation for Belarus personal number.
- Added parsing of Russian Federation registration address text into separate fields.
- Added transliteration into Latin characters of all Cyrillic characters for Russian Federation domestic passports.
- Added generation of MRZ for Russian Federation domestic passports without MRZ by its data.
- Added generation of text name of issuing authority by its code for Russian Federation domestic passports.
- Added date validation for revision FT_FIRST_ISSUE_DATE, FT_REVISION_DATE & FT_DATE_OF_CREATION.
- Added new country code XES (XC).
- Added new calculated fields FT_AGE_AT_ISSUE, FT_YEARS_SINCE_ISSUE based on date of issue of the document and date of birth for convenience.
- Fixed issue of conversion Albanian character ç into Latin c.
- Fixed issue with FT_DL_UNDER_18_DATE, FT_DL_UNDER_19_DATE, FT_DL_UNDER_21_DATE fields validation.
- Fixed issues with date of expiry parsing for some documents, that do not expire (99-99-9999).
- FT_MRZ_TYPE field now present in text comparison results.
- Fixed issue with transliteration from Greek to Latin for specific exceptional cases.

August 23, 2019 - v5.0

API:

Added a new Core framework type doctype.
Added a new scenario Capture, which allows obtaining a frame from the camera without image processing.
Added possibility to set a separate scenario for the capture button (captureButtonScenario).
Added correct display of RFID reading progress.
Added barcode parsing results (DocumentReaderBarcodeResult).
Added possibility to set the measurement system in the final results: (measureSystem).
Added possibility to get a full original image from which the final document image was obtained (returnUncroppedImage).
Added possibility to change the status text of the tooltip.
Added the ability to change the alpha of the background mask around the frame.
Added new eGraphicFieldType enum member:
- GF_PORTRAIT_OF_CHILD.
Added new eVisualFieldType enum members:
- FT_DATE_FIRST_RENEWAL,
- FT_DATE_SECOND_RENEWAL.
Added French localization.
Added new property DocumentReader.Instance().licenseResult() that contains information about the current license:
- expiryDate: license expiration date
- countryFilter: codes of countries whose documents are available for OCR (if the array is empty, it means that there are no restrictions on countries).
Updated the logic of the Ocr scenario. Now it always returns a correct image of the document.
Changed the logic of layout of the pictures for the startup animation (helpAnimationImageID), multi-page animation (multipageAnimationFrontImage, multipageAnimationBackImage) and background frame (borderBackgroundImage). Now it is possible to change the scaleType property for all the images listed above.
Updated the logic of capture button operation. Added timers of button display after the start of scanning (showCaptureButtonDelayFromStart) or after the detection of document boundaries (showCaptureButtonDelayFromDetect). By default, their values are 5 and 10 seconds, respectively.
Changed the structure of the results. Now most of them contain the property pageIndex, which contains the index of the page from which the result was obtained.
The documentType property in the final result DocumentReaderResults is now an array that contains information about each page that has been read.
In the enum eGraphicFieldType, the value GT_DOCUMENT_FRONT is replaced by the GF_DOCUMENT_IMAGE value. The value GT_DOCUMENT_REAR has been deleted. Now, to obtain the back side of the document, the pageIndex property of the graphic field (DocumentReaderGraphicField) should be used.
Corrected the logic of calculating the final field validity status (eCheckResult).
Fixed the logic of the MrzAndLocate scenario. Now it stops working only after detecting the MRZ and detecting the borders of the document containing this MRZ.
Fixed the logic of the customization properties statusPositionMultiplier and resultStatusPositionMultiplier.
