In the paper, we have focused on the problem of choosing the best set of features in the task of gender classification/recognition. Choosing a minimum set of features, that can give satisfactory results is also important in the case where only a part of the face is visible. The minimum set of features can simplify the classification process to make it useful for mobile applications. Many authors have used SVM in facial classification and recognition problems, but there are not many works using facial geometry features in the classification neither in SVM. Almost all works are based on the appearance-based methods. In the paper, we show that the classifier constructed on the base of only two or three geometric facial features can give satisfactory (though not always optimal) results with accuracy 82% and positive predictive value 87%, also in incomplete facial images. We show that Matlab and Mathematica can produce very different SVMs given the same data.
