Face Recognition on Partial and Holistic LBP Features

An algorithm for face description and recognition based on multi-resolution with multi-scale local binary pattern(multi-LBP) features is proposed.The facial image pyramid is constructed and each facial image is divided into various regions from which partial and holistic local binary patter(LBP) histograms are extracted.All LBP features of each image are concatenated to a single LBP eigenvector with different resolutions.The dimensionality of LBP features is then reduced by a local margin alignment(LMA) algorithm based on manifold,which can preserve the between-class variance.Support vector machine(SVM) is applied to classify facial images.Extensive experiments on ORL and CMU face databases clearly show the superiority of the proposed scheme over some existed algorithms,especially on the robustness of the method against different facial expressions and postures of the subjects.
