- Abstract: Periocular refers to the externally visible region of the face that surrounds
the eye socket. This feature-rich area can provide accurate identification in
unconstrained or uncooperative scenarios, where the iris or face modalities may
not offer sufficient biometric cues due to factors such as partial occlusion or
high subject-to-camera distance. The COVID-19 pandemic has further highlighted
its importance, as the ocular region remained the only visible facial area even
in controlled settings due to the widespread use of masks. This paper discusses
the state of the art in periocular biometrics, presenting an overall framework
encompassing its most significant research aspects, which include: (a) ocular
definition, acquisition, and detection; (b) identity recognition, including
combination with other modalities and use of various spectra; and (c) ocular
soft-biometric analysis. Finally, we conclude by addressing current challenges
and proposing future directions.
