Reassembling 3D thin shells using integrated template guidance and fracture region matching

Abstract

Geometric restoration that composes 3D fragmented pieces into the original complete object is an important computer graphics and geometric processing problem. Automatic and effective restoration has applications in many fields such as archeological reconstruction, digital heritage archiving, forensic evidence processing, to name a few. For example, archaeologists reconstruct ceramic fragments (sherds) into complete pots in order to analyze the information of the ancient society. Forensic scientists reassemble skull fragments into complete skull for face reconstruction and body identification. In both of these problems we need to solve a composition of digitized thin-shell fragments with different shapes, sizes, and resolutions. This problem remains very challenging.
