Abstract
Face verification technology is widely used in public safety, e-commerce, access control, and so on. We propose a novel face
verification approach, which combines a relatively new object descriptor—Histogram of Gabor Phase Patterns (HGPP), AdaBoost
Algorithm selecting HGPP features and learning binary classifier, and Quotient Image method synthesizing face images under
new illumination conditions. Although Gabor wavelets have been widely used in face recognition, previous studies mainly focus
on the magnitude information of Gabor feature, while neglect the phase information of it. We use HGPP as an attempt to utilize
the neglected Gabor phase information in face verification. Then AdaBoost algorithm trains binary classifiers, meanwhile significantly
reduce the dimension of HGPP. Further, the novel strategy that synthesizes and extends training samples with Quotient Image
method enhances our algorithm’s robustness for illumination variation. Experiments demonstrate our novel approach is able
to achieve promising face verification results under different illumination conditions.
