- Abstract
In order to improve face recognition rate using geometric and neighborhood information, a local descriptor is proposed in this paper for 3D face recognition. In this method, equal geodesic contour line of the face is extracted and re-sampled and a local descriptor that does not rely on coordinate information is extracted by the analysis of cloud distribution information of local points on the contour line. Local characteristics are weighted and rules are integrated between the corresponding points of the tested face and library set face and ultimate recognition result is obtained by using nearest neighbor classifier. Performance of the algorithm is verified in FRGV v2.0 and experimental results show the method has good recognition performance. Improvement measures are also proposed to solve the problem that the geodesic contour line is easily affected by expression in the bottom part area of human face and experimental results show the improvement method is effective.
