Definitions Edit

Biometrics Edit

The threshold is

[a] user setting for biometric systems operating in the verification or open-set identification (watchlist) tasks. The acceptance or rejection of biometric data is dependent on the match score falling above or below the threshold. The threshold is adjustable so that the biometric system can be more or less strict, depending on the requirements of any given biometric application.[1]

General Edit

A threshold is the

[t]ime, monetary unit, or resource level, placed on something, which is used as a guideline that, if exceeded, causes some type of management review to occur.[2]
