This document establishes:
terms and definitions for quantifying finger image quality;
methods used to quantify the quality of finger images; and
standardized encoding of finger image quality;
for finger images at 196,85 px/cm spatial sampling rate and a bit depth of 8 bit for the greyscale pixel intensity values scanned or captured using optical area sensors in direct contact with friction ridges.
BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
