In a \mbox{realistic} scenario, it is very likely that the lighting conditions of the probe image does not correspond to those of the gallery image, hence there is a need to handle such variations. In this work, we present a new preprocessing algorithm based on Local Binary Patterns (LBP): a texture representation is derived from the input face image before being forwarded to the classifier. The efficiency of the proposed approach is empirically demonstrated using both an appearance-based (LDA) and a feature-based (HMM) face authentication systems on two databases: BANCA and XM2VTS (with its darkened set). Conducted experiments show a significant improvement in terms of verification error rates and compare to results obtained with state-of-the-art preprocessing techniques.}, pdf = {https://publications.idiap.ch/attachments/papers/2006/heusch-AFGR-2006.pdf}, postscript = {ftp://ftp.idiap.ch/pub/papers/2006/heusch-AFGR-2006.ps.gz}, ipdmembership={vision}, } crossreferenced publications: @TECHREPORT{heusch:rr05-76, author = {Heusch, Guillaume and Rodriguez, Yann and Marcel, S{\'{e}}bastien}, projects = {Idiap}, title = {Local Binary Patterns as an Image Preprocessing for Face Authentication}, type = {Idiap-RR}, number = {Idiap-RR-76-2005}, year = {2005}, institution = {IDIAP}, abstract = {One of the major problem in face authentication systems is to deal with variations in illumination.
