We conduct experiments using a database of 960 bitmap images of 120
individuals (60 male, 60 female), extracted from the AR Face Database provided
by Martinez and Benavente*. We separate the database into
two disjoint sets: i) The training set, containing 60 images of different
people of various gender, race and age taken under natural lighting conditions
with neutral expression; ii) the test set containing 900 images (15 images
of 60 people of various gender, race and age). Each of the 15 images
were taken under the conditions described in the table below. All
images are scaled and rotated such that the centres of the eyes are aligned,
using our eye detection algorithm (not described here).

The above images are examples indicating the image capture conditions
represented in the
database, however none of these images are actually included in the
database.
