Reliability assessment (Helmer, 1993)
A double blind accuracy study was carried out by Prof. Dr. Richard Helmer. Two researchers reconstructed 12 skulls following a plan based upon the skull morphology. Each reconstruction (examples A & C) was then compared to an ante-mortem photograph of the subject (examples B) using resemblance ratings from five observers. The results suggested the reconstructions were closer resemblances to each other (50% approximate) than to the subjects (42% slight). Image courtesy of Wiley-Liss Inc.
