Facial reconstruction in forensic science

In this paper, we present a method for automated estimation of a human face given a skull remain. Our proposed method is based on three statistical models. A volumetric tetrahedral skull model encoding the variations of different skulls, a surface head model encoding the head variations, and a dense statistic of facial soft tissue thickness FSTT. All data are automatically derived from computed tomography CT head scans and optical face scans. In order to obtain a proper dense FSTT statistic, we register a skull model to each skull extracted from a CT scan and determine the FSTT value for each vertex of the skull model towards the associated extracted skin surface.

With general information about the thickness and types of tissue covering the skull at various points, the forensic sculptor can create a likeness of that individual. The skull provides clues to personal appearance. The brow ridge, the distance between the eye orbits, the shape of the nasal chamber, the shape and projection of the nasal bones, the chin's form, and the overall profile of the facial bones all determine facial features in life.

Forensic Facial Reconstruction

Facial reconstruction is a method used in the forensic field when a crime involves unidentified remains. Facial reconstruction is usually performed by a sculptor who is an expert in facial anatomy. Either way, the sculptor will work with forensic anthropologists to interpret the features of the skeleton that will ultimately help reveal the age, sex and ancestry of the victim. The sculptor can also reveal anatomical features features that are related to the body structure such as facial asymmetry, evidence of injuries like a broken nose or teeth that were lost before death.
