Putting on Glasses

Scanning people and generating realistic face models is becoming nowadays an important branch in Computer Graphics. The main applications are the creation of 3D selfies that can be immediately viewed or printed in 3D, the creation of 3D avatars for augmented or virtual reality applications, content creation for games or movies, or the developing of 3D face authentication algorithms (more robust respect to the 2D counterpart). This thesis provides an overview on a common issue that arises when scanning people wearing glasses and in turn proposes different solutions to solve or at least bypass the original problem, showing the strengths and the weaknesses. Distinct techniques for automatically putting a pair of glasses on a human face are also present. Furthermore, a study on the physical properties of glasses is documented, involving both the frame and the lenses, along with a brief description of the Blender software and its main features that were essential during the development.
