PAPILLON-POLYFACE Automated Facial Recognition System
 


 

PAPILLON-POLYFACE  has emerged as an attractive solution to address many contemporary needs for identification and verification of identity claims, in which an image of an individual's face would be matched to a pre-existing image stored in a reference database or watchlist.

POLYFACE allows users to maintain databases consisting of two galleries:

  • Enrolled facial images of known persons, captured in controlled environments
  • Facial images of unknown or unreliably known persons, including facial composites of wanted criminals

Facial images can be acquired from various sources:

  • Directly from digital cameras via POLYFACE interface enabling high-quality facial photography in compliance with требованиями ISO/IEC 19794-5:2005/ GOST R ISO/IEC 19794-5-2006 requirements
  • PAPILLON KLIM 3D system
  • PAPILLON AFIS database
  • Another POLYFACE database
  • Graphics files of standard formats
  • Flatbed scanners
  • OS clipboard

 

Besides facial images, the gallery record may contain:

  • Demographic data
  • Photos of distinctive marks (SMT photos)
  • Verbal portrait
  •  Specimen of handwriting.

PAPILLON-POLYFACE uses Firebird, an open source SQL relational database management system that allows reliable and efficient operation with database objects.


 


Creating Facial Templates

Facial recognition algorithms identity facial features by extracting landmarks from an image of the subject's face. In POLYFACE, creation of facial templates normally involves locating 28 anthropometric landmarks, 15 of which are extracted automatically.

Automatic Searches

For each newly entered image, the system searches the existing database for a biometric template that matches a submitted biometric sample, and if found, returns corresponding identities (candidates), based on a comparison score and rank. The results can be represented as a photo book.

Data Synchronization

Data synchronizability provided in POLYFACE enables creation of multi-level collections of facial images and related data that can be updated and shared quickly across jurisdictions through electronic channels.

Integration with PAPILLON AFIS

Integration with PAPILLON AFIS involves automatic transfer of data associated with every newly entered tenprint (demographics, mugshots and other photo images, verbal description of an individual's appearance and traits) to POLYFACE databases for enrollment and matching. Results of a search are transferred back to the AFIS site.

Alternatively, the POLYFACE program modules can be integrated into PAPILLON AFIS software architecture to enable multibiometric enrollment and identification.
