July 9, 2021

Product revision number: 20210709
Product revision hash: b9fa1fc33e4c9fc33b2397042abe809a6fa8fbe0
The first release of MegaMatcher 12.2 SDK line.

Algorithms:

  • Faces:
    • Added the fastest extraction speed scenario for faces. It can be enabled using a parameter. This scenario is especially useful for devices with low compute power to improve extraction time. Obviously, this results in lower quality. Use this option only if default extraction speed was found unnaceptable.
    • New face liveness detection mode optimized for high resolution images. Can be enabled using using a parameter.
    • Face/not-face filtering for existing face templates. Latest face quality algorithm can be applied to existing templates generated even with previous versions of the SDK in order to accurately remove non-face images. This feature is enabled using a parameter. When enrolling face templates to engine, if a face does not pass quality threshold it means either there are no face or low quality face is present in template and ObjectNotFound NBiometricStatus is returned. It is possible to adjust the threshold.
    • New high quality face photo background elimination algorithm. For mobile devices there is a special version which works a lot faster but is less accurate. User may choose between high quality and fast version using a parameter.
    • More accurate face landmark detection.
  • Irises:
    • Possibility to automatically determine iris position. It is beneficial to set position to left or right for irises so that matching is done only with compatible position resulting in better performance. This feature can be enabled using a parameter.
    • Improved iris extraction and matching algorithm. More accurate template is created when engine.TemplateSize=Large (default since this line). Iris templates are interoperable with the previous product lines.

New features:

  • Added parallel face extraction tutorial for C language which demonstrates how to perform tasks in parallel for maximum performance.

Fixes:

  • Fixed several issues in Activation Wizard.
  • Fixed license generation bug on Android when using BouncyCastle as the security provider.

Updates and improvements:

  • Better interoperability with older SDK versions when using dongle licensing.
  • Better issue diagnostics message on Android if Internet permission not present.
  • Fingerprint scanners:
    • Added DigitalPersona U.are.U support on ARM Linux.
    • Added support for Jenetric LIVETOUCH QUATTRO Compact scanner. Updated Jeneteric's SDK which includes advanced spoof detection and some bug fixes.
    • Added Mantra finger scanner module (MFS500 and MAPRO CX devices supported).

Product revision hash: 414d47a2a5619dcac90ccbb6c6a9f59cc79c653e
The first release of MegaMatcher 12.1 SDK line.

Algorithms:

  • Fingerprints:
    • Special fingerprint matching mode for the cases when some fingerprint records have incorrect resolution.
    • Fingerprint segmenter algorithm updated to improve handling of complex segmentation cases.
  • Faces:
    • Face liveness detection from a single frame added.
