[4.0.0] - 2021-01-11

Genius Scan SDK 4.0 is an entire rewrite from scratch of the Genius Scan SDK, using entirely new technologies and algorithms. Genius Scan 4.0 introduces breaking changes to the API.

Document Detection

The document detection has been entirely rewritten using deep learning. The document detection is more accurate and more robust to low-contrast, low-light or unusual settings.

API Change

On Android, instead of using GeniusScanLibrary.detectFrame(path), use the DocumentDetector class. On iOS, use the GSKDocumentDetector class.

Document Enhancement

New Algorithms

We used novel algorithms to improve the image filters to achieve enhanced quality and readability for your scanned documents. You can expect better removal of shadows, white-balancing, and treatment of the colors in text documents.

In automatic mode, the document enhancement pipeline can now automatically select one of the four filters: no filter if the image doesn’t contain any document, black and white if the image is a text document with little color, color for text documents with some colors, or photo when the document mainly contains visuals but not so much text.

Edge Cleaning

Edge cleaning is a powerful enhancement that cleans up the edges of the documents. Often, after you crop a scan, some artifacts are left on the edges. The edge cleaning cleans them up. This step results in a cleaner document and helps with the accuracy of the OCR step. Edge cleaning only applies to the monochrome, black and white, and color filters.

API Change

The document enhancement pipeline is available through a single processor object set up with configuration objects. Use the ScanProcessor on Android or the GSKScanProcessor on iOS instead of the static methods on GeniusScanLibrary and GSK. When creating a processor, use the associated configuration object to tune the processing to your liking.

ScanFlow

We’ve renamed the ScannerUI framework into ScanFlow.

We’ve simplified the ScanFlow module to two main screens: a Camera screen and a Scan Review screen, from which one can change the filter and edit the cropping area of the current page.

The batch scanning mode is now streamlined: after validating a page on the post-processing screen, instead of being prompted to add a new page, the user is brought back to the camera screen. Hitting the Done button validates the scanned pages and terminates the flow. Hitting the Cancel button cancels the entire scan flow after a confirmation.

API Change

On Android, the class containing all the static methods to manage the scan flow has been renamed from GeniusScanSdkUI to ScanFlow.

PDF Generation

We’ve made several changes to optimize the size of PDF files created with the SDK. When using the Monochrome filter, you have the ability to save the output as monochrome 1-bit PNG images. Resulting PDF files using these PNG images are up to 10 times smaller.

Integration

iOS

The SDK is now packaged as XCFrameworks. We’ve removed support for Carthage.

Android

All package names and Maven articfact groups have changed from com.thegrizzlylabs.geniusscan.sdk to com.geniusscansdk to match our website URL.

Modules have also been renamed as follows:

  • gs-sdk-core into gssdk-core
  • gs-sdk-ui into gssdk-scanflow
  • gs-sdk-ocr into gs-sdk-ocr

Other Changes

  • Improve API documentation. Up-to-date API documentation is now provided directly on the geniusscansdk.com website.
  • Rewrite iOS demo apps in Swift.
  • Large API simplifications.
  • Remove the Android interface ScanContainer which was used to hold the result of a capture and replace it with a File object.
  • Improve performance of algorithms.

Improved ScanFlow UI

We’ve simplified the ScanFlow module to 2 main screens: a Camera screen, and a Post-processing screen, from which one can change the filter and edit the cropping area of the current page.

Also, the batch scanning mode has been changed: after validating a page on the post-processing screen, the user is brought back to the Camera screen. Hitting the Done button validates the scanned pages and terminates the flow. Hitting the Cancel button cancels the entire scan flow after a confirmation.

[4.0.0-beta6] - 2020-10-26

[4.0.0-beta5] - 2020-10-23

  • [iOS, Android] Improve the document processor API to avoid confusing parameter combinations.

Edge Cleaning

Edge cleaning is a powerful enhancement that cleans up the edges of the documents. Often, after you crop a document, some artifacts are left on the edges of the document. The edge cleaning cleans them up. This results in a cleaner document and helps with the accuracy of the OCR step.

  • [Android] Add ability to set an additional camera frame processing. A onPreviewFrame method has been added to the CameraManager.Callback.

[4.0.0-beta3] - 2020-10-07

Best filter detection

The Best filter detection algorithm, which takes an image as input and returns the best filter to apply to this image, has been completely changed. It used to return only two outputs: Black & White or Photo. It now has 4 outputs:

  • None when the image does not contain a document
  • Black & White for text documents with very little color
  • Color for text documents with some color
  • Photo when the document contains mainly graphic parts and little text

Other changes

  • [Android] Revert incorrect renaming of the UI package in the Core module
  • [Core] The document detection now returns an empty quadrangle when no document has been detected on the image. A full quadrangle is returned when the detected document fills the entire image (e.g. no crop is needed).

[4.0.0-beta2] - 2020-10-05

  • Fix documentation and demo apps

[4.0.0-beta1] - 2020-10-02

Document detection

Document detection has been entirely rewritten using deep learning and a new interface is now available for Android and iOS.

On Android, instead of using GeniusScanLibrary.detectFrame(path), you need to build a CnnDocumentDetection object and call one of the detectDocument methods on it. Similarly, on iOS, instead of using [GSK detectQuadrangleFromImage:imageOutOfCamera options:0], use the GSKDocumentDetector class and the detectQuadrangle* methods.

Scan processor

A new interface is also available for the different scan processing operations such as perspective correction, filtering and distortion correction. A single call is now needed to process an image and get a clean and readable document.

On Android, the corresponding methods have been removed from the GeniusScanLibrary class and have been replaced by a ScanProcessor class. On iOS, the GSKDocumentProcessor class replaces previous methods from GSKCore.

Image filters

The different image filters (Photo, Color, Black and White, Monochrome) have also been rewritten from scratch using novel algorithms to improve the quality and readability of the scanned documents. This results in a better removal of shadows, a correction of the colored tint that appears on some documents because of ambient light, and a better treatment of colors in text documents.

Monochrome filter and smaller PDF files

We’ve made several changes to optimize the size of PDF files created with the SDK. When using the Monochrome filter, you have the ability to save the output as monochrome 1-bit PNG images. Resulting PDF files using these PNG images are up to 10 times smaller.

Other changes

  • [Cordova ReactNative Flutter] iOS: Change the output format to match the documentation. Now, the scans and the generated PDF all have a URL in the form file:///path/to/file.ext.

[3.0.25] - 2020-10-01

  • [Core] Android: Properly throw an exception in perspective correction when quadrangle is invalid.
  • [Core] iOS: Fix crash in perspective correction when two vertices of the quadrangle are really close.

[3.0.23] - 2020-07-21

  • [UI] Improve translations, mainly in Turkish.
  • [Android] Keep symbols in AARs to be able to track crashes (eg with Firebase Crashlytics). This shouldn’t result in bigger APKs since native symbols are stripped when built in Release mode.

[3.0.22] - 2020-07-15

  • [OCR] Improve error reporting in TextLayoutToTextConverter.
  • [UI] Improve German localization.
  • [UI] iOS: Add cancel button when picking an image from the Photos or scanning directly from a URL.
