Abstract:
This thesis is an investigation into the use of Volume Graphics techniques for the purpose of forensic facial reconstruction. The thesis also examines the rapid creation of a light volume for the accurate rendering of light within a scene. The main achievements of this thesis are: an examination of forensic facial reconstruction techniques, both manual and automatic; identification of weaknesses of these methods and an improved automatic method using a volume graphics approach; a general introduction to the rapidly evolving field of volume graphics; the introduction of a technique for calculating fast, accurate measurements of light intensities inside a volume dataset. This work has demonstrated that it is now feasible to use a computer to reconstruct the face of an unknown person given his/her skull without allowing artistic interpretation. It has also demonstrated that it is computationally feasible to calculate a “light volume” to store light intensities at voxel points within a volume, thus allowing for much faster recreation of shadowing effects e.g. during rendering. Part of this research was presented by the candidate at the 19th Eurographics UK conference at the University College, London, 2001.
