Face Reconstruction. Selection of Vertices According to Cylindrical Projection. Fast Deformation Method

Nowadays exist many different methods of computer assisted face reconstruction. Part of them are based on the deformation of the model face. Article presents this kind of method which incorporates the fast methods of deformation of the triangle mesh and vertices selection. Importance of the forensic face reconstruction with no doubt is known for everyone. When other methods of identification of the victim of crime failed forensic anthropologist could help to solve the case. These matters are much often present in computer visualisation papers but yet there is not available good enough complex solution. Nowadays personal computers are fast enough and have enough memory to run complicated algorithms which could quickly solve problems of analyzing large data sets. In addition, compilers are day by day better and generate more optimal programs. Time is a very important aspect in a computer reconstruction and visualization systems, even more important than quality. There are few different approaches how to do a face reconstruction. Some of them try to just copy the methodology of the traditional clay face reconstruction [1]. There is also a lot of methods which use deformable models of face [3]. All of them as a base of the reconstruction use a 3d triangle mesh model of skull generated by segmentation and triangulation of CAT scans or from 3d scanners 2. ANATOMICAL LANDMARKS In the computer assisted reconstruction like in the traditional method one of the most important factors is the set of properly placed markers. Each marker should be set in the characteristic anatomical landmark of the skull. The number of landmarks depends on a chosen method and includes from one dozen to several dozen places. The solution proposed here uses 21
