abstract = "We present an automatic face verification system inspired by known
properties of biological systems. In the proposed algorithm the
whole image is converted from the spatial to polar frequency
domain by a Fourier-Bessel Transform (FBT). Using the whole image
is compared to the case where only face image regions (local
analysis) are considered. The resulting representations are
embedded in a dissimilarity space, where each image is represented
by its distance to all the other images, and a Pseudo-Fisher
discriminator is built. Verification test results on the FERET
database showed that the local-based algorithm outperforms the
global-FBT version. The local-FBT algorithm performed as
state-of-the-art methods under different testing conditions,
indicating that the proposed system is highly robust for
expression, age, and illumination variations. We also evaluated
the performance of the proposed system under strong occlusion
conditions and found that it is highly robust for up to 50% of
face occlusion. Finally, we automated completely the verification
system by implementing face and eye detection algorithms. Under
this condition, the local approach was only slightly superior to
the global approach.",
