Periocular Biometrics: A Modality for Unconstrained Scenarios
Periocular refers to the region of the face that surrounds the eye socket.
This is a feature-rich area that can be used by itself to determine the
identity of an individual. It is especially useful when the iris or the face
cannot be reliably acquired. This can be the case of unconstrained or
uncooperative scenarios, where the face may appear partially occluded, or the
subject-to-camera distance may be high. However, it has received revived
attention during the pandemic due to masked faces, leaving the ocular region as
the only visible facial area, even in controlled scenarios. This paper
discusses the state-of-the-art of periocular biometrics, giving an overall
framework of its most significant research aspects
