This competition comprises two tasks:

  • cross spectral iris recognition
  • cross spectral periocular recognition

Each participant can participate with methods for either iris recognition, periocular recognition or both tasks.

Cross-spectrum iris recognition competition:

The iris is well known as an accurate biometric trait. Recent datasets for iris recognition and its applications in the mobile biometrics scenario tend to capture images in visible wavelengths. However, in less constrained settings when capturing under visible wavelength light it is hard to capture iris images with enough quality for reliable recognition. The cross spectrum iris imaging allows us to maintain backward compatibility with existing databases and devices but at the same time to meet the demand of robust iris recognition capabilities; in mobile devices for example.

Cross-spectrum periocular recognition competition:

This biometric trait, comprising the whole eye region is therefore broader than the iris and allows overcoming the limitations caused to recognition by noisy and less quality iris images. The periocular recognition is also interesting to be used in on-the-move scenarios which again involve less controlled image acquisition scenarios and therefore less quality iris images.

Dataset features

The CROSS-EYED - "Reading Cross-spectrum Iris/Periocular Dataset" - is the benchmark dataset for the competition.
It is composed by eye images both visible (VW/RGB) and near infra-red (NIR).

The CROSS-EYED images used for this competition are captured with a custom made dual spectrum imaging sensor, which acquires near infrared and colour images synchronously, eliminating any possible influence of pupil dilation on the reported accuracies. The images are acquired from a distance between 1.5 and 2 meters.

The images acquired under near infrared wavelength have a single channel, while the visible spectrum iris images contain 3 channels of information.

Key features:

  • Cross-spectrum: synchronised Near Infra-Red + Visible range
  • Captured from distance: 1-2m
  • Realistic indoor environment with realistic illumination condition
  • A large variation in ethnicity and eye colour
  • Realistic and challenging illumination reflection

The best evaluated algorithm will win the "Cross-spectrum Iris/Periocular Recognition competition" (CROSS-EYED) award at BTAS 2016.
