Detailed Description

Biometric information relating to finger images and derived information.

The Finger package gathers all finger related matters, including classes to represent finger minutiae and helper functions for conversion between biometric representations. Contained within this namespace are classes to represent specific record formats, such as ANSI/NIST finger image records.

Position

enum class BiometricEvaluation::Finger::Position

strong

Finger position codes.

These codes match those in ANSI/NIST. Other minutiae formats may have to map codes into this set.
