There are more minutiae encoding standards that define minutiae angle granularity differently:

  • XYT format (NBIS software by NIST based on ANSI/NIST-ITL 1-2007 standard): 1 degree (valid values 0-359)
  • ISO/IEC 19794-2 format: 1.40625 degree (valid values 0-255)
  • ANSI INCITS 378: 2 degrees (valid values 0-179)

Make sure our extracted minutiae points are converted to the correct representation depending on the selected matching algorithm.

Notes:
Bozorth3 matcher takes minutiae in XYT format. (Option M1 expects minutiae encoded in ANSI INCITS 378 format).
Suprema SDK matcher takes minutiae in ISO/IEC format.
