Η creation images of the suspects of a crime energys, which will have been created using only the DNA of the perpetrators, could be the script of a movie. However, his researchers Pennsylvania State University have managed to create the technology that turns the scenario into reality.
More specifically, researcher Mark Shriver and his team have developed an application that can produce a three-dimensional representation of individuals who have left a DNA sample at a crime scene and are suspected, without any evidence of their external appearance.
The research team used 600D images of about 7.000 volunteers, men and women, who came from various races and ethnic groups. More than XNUMX were subsequently created digitally points αναφοράς, βασισμένα σε χαρακτηριστικά προσώπου και στη συνέχεια έγινε καταγραφή της ακριβούς θέσης του κάθε ενός από αυτά τα σημεία. Τα «πλέγματα» που δημιουργήθηκαν, χρησιμοποιήθηκαν στη συνέχεια για τη measurement of differences in facial features from person to person.
Then, a computational model was created that could identify how the person's characteristics were affected by gender, genes, and race. Thus, the team of researchers discovered that since the sex and race of the individual were selected, there were 20 genes with 24 versions that could be used to safely predict the shape and characteristics of a person.
In order to improve the system, Pennsylvania State University researchers will expand the application database to allow for more accurate forecasts. For this reason 30.000 reference points will be used as opposed to 7.000 in the initial phase of the survey.
As reported in a Tech Times report, the results of this application could not be accepted by any court in the United States. However, they could be used to create three-dimensional images that could replace the known police suspects.
