In this work, we propose and experiment an original solution to 3D face recognition that supports accurate face matching also in cases where just some parts of probe scans are available. In the proposed approach, distinguishing traits of the face are captured by first extracting keypoints of the 3D depth image and then measuring how the face depth changes along facial sections between pairs of keypoints. Face similarity is evaluated by comparing facial sections across inlier pairs of keypoints that match between probe and gallery scans. In doing so, facial sections of the gallery scans are associated with a saliency measure in order to distinguish sections that model characterizing traits of some subjects from sections that are frequently observed in the face of many different subjects. The recognition accuracy of the approach is experimented using the Face Recognition Grand Challenge v2.0 dataset.

Abstract

In this work, we propose and experiment an original solution to 3D face recognition that supports accurate face matching also in cases where just some parts of probe scans are available. In the proposed approach, distinguishing traits of the face are captured by first extracting keypoints of the 3D depth image and then measuring how the face depth changes along facial sections between pairs of keypoints. Face similarity is evaluated by comparing facial sections across inlier pairs of keypoints that match between probe and gallery scans. In doing so, facial sections of the gallery scans are associated with a saliency measure in order to distinguish sections that model characterizing traits of some subjects from sections that are frequently observed in the face of many different subjects. The recognition accuracy of the approach is experimented using the Face Recognition Grand Challenge v2.0 dataset.
