| |
Human skulls are the target objects in craniofacial surgery planning, forensic investigation and
physical anthropological study. In cramofacial surgery planning, a patient's skull can be defective due to impact injury, congenital deformity or tumor. To repair the patient's skull accurately, a surgeon requires a normal reference model to guide his operations. In forensic investigation, a victim's skull can be defective due to impact injury caused by violence. To identify the victim, an investigator needs to reconstruct the victim's skull followed by facial reconstruction. In physical anthropological study, a human or non-human hominid skull can be defective in many ways including natural causes. To fully characterize the skulls, an anthropologist needs to reconstruc the subject's skull from the defectivfe ones. |

| Research Goal |
| |
Our research goal is to develop software tools and algorithms for reconstruction of normal skulls from defective skulls that are applicable to craniofacial surgery, forensic investigation and physical anthropology.
