摘要:
The Local Binary Pattern (LBP) algorithm is popular and widely used in 2D pattern recognition. While in this paper, we successfully apply the LBP on 3D face recognition for the first time, and propose a novel framework for 3D face recognition based on LBP. We first normalize the 3D faces, and divide them into many block regions based on face features. Then, the LBP operator is applied on each block region, and the LBP histogram sequence of all the regions for each individual is used to represent the 3D face. In recognition step, we present three metric methods based on the LBP operator, 3DLBP, self-adaptive LBP (SLBP), and the weighted LBP (WLBP), to measure the similarity between any two 3D faces. At last, we test the proposed algorithm on BJUT-3D face database and achieve exciting recognition performances, which demonstrates that it is feasible and effective to apply LBP on 3D face recognition. © 2010 Binary Information Press.
