  As a biometric palmprints have been largely under-utilized, but they offer
some advantages over fingerprints and facial biometrics. Recent improvements in
imaging capabilities on handheld and wearable consumer devices have re-awakened
interest in the use fo palmprints. The aim of this paper is to provide a
comprehensive review of state-of-the-art methods for palmprint recognition
including Region of Interest extraction methods, feature extraction approaches
and matching algorithms along with overview of available palmprint datasets in
order to understand the latest trends and research dynamics in the palmprint
recognition field.
