Abstract
A vast majority of the existing face recognition techniques encounter misclassifications when there is a large variation of the
subject in terms of pose, illumination and expression as well as artefact such as occlusion. With the usage of Local Binary Pattern
(LBP), local feature representation which preserves local primitives and texture information, robust against illumination,
expression and occlusion was realized in the feature extraction process. Mahalanobis distance and k-NN classifier were
employed for recognition as basis for comparison. An assessment of both algorithms was considered. It was observed that
Mahalanobis distance measure outperformed the k-NN classifier for access control and recognition system due to its high
recognition rate (98.4%), genuine acceptance rate (98.37) and its stern adherence to both FAR and FRR (0.0144, 1.568) than k-
NN with 94.9% and (0.392 and 2.895) respectively. This result demonstrates the robustness of Mahalanobis distance classifier for
use access control system.
