Our gender classification approach relies on biological landmarks as basic points to determine different classification features.Certain landmarks were used for each facial region to select Euclidean distance，geodesic distances，and geodesic path curvaturesfollowingtherecommendationsof Toma[27].The aim of this experiment was to determine the landmark pairs that define the best geodesic-curvature based features（as described above）for gender discrimination.To achieve this aim，the paths connecting landmarks were ranked according to their individual classification accuracies obtained with the best combination of features（geodesic distance and geodesic path curvatures）from Experiment 4.Table 6 ranks inter-landmark paths for each face region，while Fig.8 shows the three geodesic paths with the highest rank for each region.
