of the face template. Similar to the gait module, as the size of the
templates increases the FRR increases and FAR decreases.
Although matching feature vectors extracted within the same
sequence produces low error rates in general, inter-sequence matches
are a more challenging task especially when the variances present in
the enrolment sequence differ much from these present in the match-
ing sequence. Face recognition algorithms are known to be sensitive
to data outliers in terms of incorrectly normalised samples and severe
intrapersonal variations such as extreme facial expressions and occlu-
sions ...
