Abstract: | Facial reconstruction can be used as a forensic technique to identify a person, when no other identification method is applicable.
The facial soft tissue thickness applied to the skull is crucial when performing an accurate facial reconstruction. Historically,
scientists developed several techniques to measure the soft tissue of the face. It was their aim, to build a database of a
unique point-set, differentiated by gender, age, ethnic origin, BMI. All used a limited number of landmarks and an inaccurate
measuring technique. We developed a contact-free and precise measuring technique, using low-dose CT and holographic data.
Due to the extremely short exposure time, the holographic measurement is very precise. We lay out our first experiences to
create a facial soft tissue layer map of the face. |
