| Summary: | Craniofacial superimposition are used in cases where one has found an
unknown human skull. The purpose of this research was to develop craniofacial
superimposition by applying mathematical programme to increase the credibility
of craniofacial superimposition in Thailand. To calculate the overlay position of
face-real skull photo and face photo from the same owner were compared to
the face-randomised skull photo and face photo. This study was carried out on a
sample of 20 skulls, divided into 10 male skulls and 10 female skulls. All samples
of bones were taken from the Forensic Osteology Research Center (FORC), Faculty
of Medicine, Chiang Mai University. Skull and face photography of the deceased
took only the front-straight face position. The similarity was found out from edges
of them that compared at important points with the mathematical programme,
in which the researchers applied functions and mathematical principles of
matrix and logical. In each individual experiment between face-real skull and
face-randomised skull, the results were recorded and explained in the form of
qualitative experiments. From the experiment found that the used programme can
be able to correctly assess the similarity are 19 cases of 20 cases. Craniofacial
superimposition can save the budget of DNA testing and can be screening for the
initial assumption. This research will be able to facilitate, work faster, more reliable
and save budget in the identifying process. |
