This paper presents a thorough study of gender classification methodologies performing on neutral, expressive
and partially occluded faces, when they are used in all possible arrangements of training and testing roles. A comprehensive
comparison of two representation approaches (global and local), three types of features (grey levels,
PCA and LBP), three classifiers (1-NN, PCA + LDA and SVM) and two performance measures (CCR and d′) is provided
over single- and cross-database experiments. Experiments revealed some interesting findings, which were
supported by three non-parametric statistical tests: when training and test sets contain different types of faces,
local models using the 1-NN rule outperform global approaches, even those using SVM classifiers; however,
with the same type of faces, even if the acquisition conditions are diverse, the statistical tests could not reject
the null hypothesis of equal performance of global SVMs and local 1-NNs. [-]
