Facial Model Deformation Based on Landmarks Using Laplacian

Abstract

Reconstructing a 3D face model from an unknown skull provides many benefits in the fields of archeology, anthropology, and forensic investigation. Computer systems for 3D facial reconstruction provide a big advantage in reducing time consumption. In this paper, we propose computer-based 3D face reconstruction for Indonesian from CT Scan images using facial model deformation which is limited by knowledge of soft tissue thicknesses. First, we prepare supporting data in the form of general face models and FSTTs for Indonesians. Then we set landmarks on the unknown skulls. By adding FSTT to the skull landmarks, we get landmark coordinates from predicted face. Finally, we performed Laplacian deformation on the face model so that its shape and size matched the landmark coordinates of the predicted face.
