compare the obtained results with those achieved by other methods in the literature.
Scenario evaluations typically do not use public datasets, but require sets of specif-
ically acquired biometric data to describe the evaluated scenario in an exhaustive
manner.
Studies have examined the accuracy evaluation of symmetric matching func-
tions [61]. For two biometric samples A and B, a matching function M is symmetric
if M(A, B) = M(B, A). The evaluation procedures reported here are those pro-
posed in [61] and can be applied to both symmetric and asymmetric matching
functions, in which M(A, B) = M(B, A). Accuracy evaluation techniq ...
