Special issue on novel insights on ocular biometrics

Ocular biometrics have a great potential to support biometric applications, due to the unique features of the ocular traits. Notwithstanding this, the related lines of research still present several open issues,which justify the ongoing research efforts. For instance, the relatively recent emergence of the periocular and sclera traits makes it worth recording the progresses in those areas. Furthermore,wider and deeper investigations regarding all the traits underlying the ocular region and the best way to combine them still needs to be thoroughly undertaken. This would not only improve the recognition robustness, but alsomake perceiving the potential of this kind of solutions in solving problems in the biometrics domain. Moreover, “systems interpretability”, “weakly/partial supervised recognition” or “forensics evidence and biometric recognition” add interest to an already rich field of research. This special issue aims at providing a platform to publish and record the recent research on ocular biometrics in order to push the state-of-the-art forward.
