Craniofacial Superimposition Based on Genetic Algorithms and Fuzzy Location of Cephalometric Landmarks

摘要

Craniofacial superimposition is the second stage of a complex forensic technique that aims to identify a missing person from a photograph (or video shot) and the skull found. This specific task is devoted to find the most appropriate pose of the skull to be projected onto the photograph. The process is guided by a number of landmarks identified both in the skull (craniometric landmarks) and in the photograph (cephalometric landmarks). In this contribution we extend our previous genetic algorithm-based approach to the problem by considering the uncertainty involved in the location of the cephalometric landmarks. This proposal is tested over two real cases solved by the Physical Anthropology lab at the University of Granada (Spain).
