Face recognition has received a great deal of attention from the scientific and industrial communities over the past several decades owing to its wide range of applications in information security and access control law enforcement surveillance and more generally image understanding. In this paper we combine KLDAcombination of LBP and GABOR features with gradient face featureswhich are more resistive to the noise effects for more effective recognition process. Specifically we make three main contributions i we present a simple and efficient preprocessing chain that eliminates most of the effects of changing illumination while still preserving the essential appearance details that are needed for recognition ii we introduce Local Ternary Patterns LTP a generalization of the Local Binary Pattern LBP local texture descriptor that is more discriminant and less sensitive to noise in uniform regions and we show that replacing comparisons based on local spatial histograms with a distance transform based similarity metric further improves the performance of LBPLTP based face recognition and iii we further improve robustness by adding Kernel PCA feature extraction and incorporating rich local appearance cues from two complementary sources - Gabor wavelets and LBP - showing that the combination is considerably more accurate than either feature set alone.
