"Age and sex are essential for the identification of corpses, and the pubis is especially relevant for this purpose. In our study, we exploited the great capacity of computer systems to discriminate between the different gray shades in a histogram (the human eye only can discriminate 64) to determine how histograms can provide information about age and sex", Lopez Alcaraz states. The researcher notes that this technique might be useful in virtopsies or virtual autopsies. "At present, the main drawback of virtual autopsy is that it cannot replace the macroscopic analysis of tissues for the identification of potential pathologies, determining whether an injury was inflicted before or after death, assessing the course of an injury...etc. As the new technique is based on image analysis, it can be applied to virtual autopsy to provide many more answers than traditional analysis methods.

The researcher affirms that this is a step forward in the field of Forensic Anthropology. "We should replace traditional osteological methods with new technologies and exploit the advantages of the visual communications and image era", the researcher states.

In addition, this study contradicts the traditional assumption in Forensic Anthropology that the pubis is only useful for the identification of corpses in the age range of 20 to 40 years. "We obtained excellent results in the identification of corpses of people older than 50 years, especially in men", the author notes.
