Special Issue on " An insight on eye biometrics"

The purpose of this special issue has been to give the opportunity to researchers interested in detection and recognition methods based on all eye-related biometrics to have a common place to present all aspects of their closely related research activities. Many valuable contributions on eye biometrics such as iris pattern, retinal pattern, periocular regions, gaze and eye tracking have been published in the past, but this "Insight on Eye Biometrics" is the first special issue gathering contributions from researchers working on different eye biometrics. It is interesting pointing out the significant presence of papers devoted to present techniques based on eye movements. Being new-comes, they are presently an object of advanced investigations.
