State of the Art of Quality Assessment of Facial Images

no code implementations15 Nov 2022 Johannes Merkle, Christian Rathgeb, Benjamin Tams, Dhay-Parn Lou, André Dörsch, Pawel Drozdowski

The goal of the project "Facial Metrics for EES" is to develop, implement and publish an open source algorithm for the quality assessment of facial images (OFIQ) for face recognition, in particular for border control scenarios. 1 In order to stimulate the harmonization of the requirements and practices applied for QA for facial images, the insights gained and algorithms developed in the project will be contributed to the current (2022) revision of the ISO/IEC 29794-5 standard.

Security of the Improved Fuzzy Vault Scheme in the Presence of Record Multiplicity (Full Version)

no code implementations18 Dec 2013 Johannes Merkle, Benjamin Tams

Recently, Blanton and Aliasgari have shown that the relation of two improved fuzzy vault records of the same individual may be determined by solving a system of non-linear equations.
