We propose an automatic facial landmarks detection in 3D mesh manifold. The method is based on 3D Constrained Local Model (CLM) which learns both global variations in 3D face scan and local ones around every vertex landmark. Differently from the other approaches of CLM, our contribution is a full 3D mesh. The framework exploits the intrinsic 3D features around the mesh vertices by utilizing histogram-based mesh Local Binary Patterns (mesh-LBP). The experiments are conducted on publicly available 3D face scans Bosphorus database.
