Ensemble of patterns of oriented edge magnitudes descriptors for face recognition


In this work we propose an ensemble of descriptors for face recognition. Starting from the base patterns of the oriented edge magnitudes (POEM) descriptor, we developed different ensembles by varying the preprocessing techniques, the parameters for extracting the accumulated magnitude images (AM), and the parameters of the local binary patterns (LBP) applied to AM. Our best proposed ensemble works well regardless of whether dimensionality reduction by principal component analysis (PCA) is performed or not before the matching step. We validate our approach using the FERET datasets and the Labeled Faces in the Wild (LFW) dataset. We obtain very high performance rates in both datasets. To the best of our knowledge, we obtain one of the highest performances reported in the literature on the FERET datasets. We want to stress that our ensemble obtains these results without combining different texture descriptors and without any supervised approach or transform. Finally, two cloud use cases are proposed. The MATLAB source of our best approach will be freely available: http://www.dei.unipd.it/wdyn/?IDsezione=3314&IDgruppo_pass=124
