Set 1 is comprised of face and fingerprint scores from the same
set of 517 individuals. For each individual, the set contains one score
from the comparison of two right index fingerprints, one score from the
comparison of two left index fingerprints, and two scores (from two
separate matchers) from the comparison of two frontal faces. The
fingerprint images and the face images from which these scores were
computed are from the same person (i.e. the chimera assumption is not in
use) at the same time (and the dates are provided).
The non-matching scores from the full
cross-comparison are also included.

Set 2 is comprised of fingerprint scores from one system
run on images of 6000 individuals.
For each individual, the set contains
one score from the comparison of two left index fingerprints,
and another from two right index fingerprints.
The non-matching scores from the left
vs. left and right vs. right cross-comparisons are also included.

Set 3 contains scores from two face systems run on images
from 3000 individuals. For each individual, the set contains one score
from the comparison of face A with a later face, B, and a score from face
A and another later face, C. This data is provided for each of two
mid-2002 face recognition algorithms |
