The field of medicine has integrated with law and
regulation in the form of forensic medicine. While the field of
medicine, as a whole, is leaping forward by integrating computer
solutions, Forensic Medicine- particularly in developing regions
such as Sri Lanka- is lacking innovative computer integrations.
The process of forensic facial reconstruction in particular, is still
at its infancy in Sri Lanka, and is yet to utilize the advanced
technologies of other countries. Hence introducing a more
efficient multimedia based technique to the local forensic officials
in order to improve the efficiency and the accuracy of the
reconstructions is the aim of this study. In contrast to the facial
reconstructions conducted in other countries, this study
introduces a novel semi-automated method of computer aided
digital sculpting to the field of forensic medicine. The adopted
process involved, acquiring a 3D model of the skull and digitally
sculpting muscles in a 3D environment, followed by adding
different facial features to improve identification. The research
also encompassed a tissue thickness analysis and a facial
component analysis, both of which were conducted for the first
time on Sri Lankans since both were needed to improve the
accuracy of the final output. This procedure was attempted on
cases of the age category 20-30 and of medium weight. The
outputs and the process were evaluated with different parties
such as general public, forensic officials, lawyers and CID all of
which yielded true positive results. The ultimate goal of
conducting the study was to understand and overcome the
challenges faced in developing this novel application for the Sri
Lankan Forensic officials and to establish the first unit for facial
reconstruction in Sri Lanka.
