WebFace recognition gives a false match rate of around 1 in 1000. For single-eye iris recognition, Mansfield and Rejman-Greene (2003) quote a false-match rate of 1 in 1,000,000. Using two eyes improves the rate considerably. These rates do not allow you to predict how many false matches there will be in any single small-scale test. Webwork. Section 4 presents an analysis of false match rate (FMR) and false non-match rate (FNMR) as a function of the matcher decision threshold. Section 5 describes differences in the impostor and genuine distributions between cohorts. Section 6 considers how differences in image quality between cohorts are related to differences in accuracy.
