Large-scale testing involving more than a trillion comparisons between the iris patterns of different persons has confirmed that the entropy of IrisCodes is large enough to deliver collision avoidance (absence of False Matches) in population sizes of national, continental, and even planetary scale. This short paper explains how the entropy of this biometric achieves it.

Complex-valued Iris Recognition Network
This work designs a fully complex-valued neural network that can better capture the multi-scale, multi-resolution, and multi-orientation phase and amplitude features of the iris texture and exploits visualization schemes to convey how thecomplex-valued network, when in comparison to standard real-valued networks, extract fundamentally different features from the iri texture.

Radial correlations in iris patterns, and mutual information within IrisCodes
The authors measured the mutual information entailed by radial correlations within each of 632,500 different iris patterns from persons of 152 nationalities and show that a non-uniform allocation of encoding resolution radially leads to significant performance improvements by reducing redundancy.

A simple two-state hidden Markov model is shown to emulate exactly the statistics of bit sequences generated both from natural and white noise iris images, including their imposter distributions, and may be useful for generating large synthetic IrisCode databases.
Face recognition accuracy of forensic examiners, superrecognizers, and face recognition algorithms
In a comprehensive comparison of face identification by humans and computers, it is found that forensic facial examiners, facial reviewers, and superrecognizers were more accurate than fingerprint examiners and students on a challenging face identification test.
The MegaFace Benchmark: 1 Million Faces for Recognition at Scale
The MegaFace dataset is assembled, both for identification and verification performance, and performance with respect to pose and a persons age is evaluated, as a function of training data size (#photos and #people).
