Proficiency test results and discussion
Soft biometrics have been widely considered as a complementary way of identifying persons. By looking for specific characteristics of individuals such as birthmarks, scars, the color of the eye, ethnicity, etc., a second step of individual identification is evaluated, thus complementing the results of any other biometrics modality. As a soft biometric, Tattoo is of special interest for applications related to identifying suspects in a criminal investigation. Such a trait can be used in a law enforcement matching system to help suspects’ identification or even in linking them to a hate or criminal group, given a large gallery of criminals’ tattoos in a police dataset that should be matched (or not) with the suspect’s tattoo. However, the efficiency of developing such image analytic systems are by nature dependent on real probe and gallery data that are difficult to acquire in realworld situations. In this report, we describe the organization, accomplishment, and main outcomes of the proficiency test organized jointly by the European Commission’s Joint Research Centre unit T.2 at Ispra, Italy, an the Europol Innovation lab in tattoo soft biometrics using artificially generated data. This proficiency test aimed at assessing the maturity of tattoo recognition procedures in videos containing avatars that reproduce some challenges found in real data. The proficiency test involved the participation of 8 teams from law enforcement agencies, forensic institutes, universities, and companies.
