abstract = "Human faces are known to present large variability due to factors
like pose and facial expression variations, changes in
illumination and occlusion, among others, thus making face
verification a very challenging problem. In this paper we address
the problem of face verification with special interest on how to
reduce degradation usually associated with face images acquired
under uncontrolled environments. The approach we propose in this
paper starts with a preprocessing step to correct in-plane face
orientation and to compensate for illumination changes. SURF
features are then extracted, which adds to the method a certain
degree of invariance to pose, facial expression and other sources
of variation. Taking the SURF features as input, an original
pairwise face matching procedure is performed. The resulting
matching scores are stored in a similarity matrix, which is then
evaluated. An experimental study has revealed that the proposed
approach produced the best ROC curve when compared to published
work regarding the unsupervised setup of the Labeled Faces in the
Wild (LFW) face database.",
