Landmark Detection on 3D Face Scans by Facial Model Registration (2008)
Tristan Whitmarsh, Remco C. Veltkamp, Michela Spagnuolo, Simone Marini, Frank Ter Haar
Abstract. This paper describes a way to locate landmarks on a 3D face scan, by registering a facial model to the scan data, and then mapping the landmark location from the model to the data.
Mapping independent triangulation of parametric surfaces (2008)
Marco Attene, Bianca Falcidieno, Michela Spagnuolo
Typical methods for the triangulation of parametric surfaces use a sampling of the parameter space, and the wrong choice of parameterization can spoil a triangulation or even cause the algorithm to...
