3D face recognition has gained growing attention in the last years,mainly because both the limitations of 2D images and the advances in 3D imagingsensors. This paper proposes a novel approach to perform 3D face matchingby using a new metric, called the Surface Interpenetration Measure (SIM).The experimental results include a comparison with a state-of-art work presentedin the literature and show that the SIM is very discriminatory as confrontedwith other metrics. The experiments were performed using two different databasesand the obtained results were quite similar, showing the robustness of ourapproach.
