ISO/IEC 19794-6:2011

Information technology - Biometric data interchange formats - Part 6: Iris image data

ISO/IEC 19794-6:2011 specifies iris image interchange formats for biometric enrolment, verification and identification systems. The image information might be stored as

  • an array of intensity values optionally compressed with ISO/IEC 15948 or ISO/IEC 15444, or
  • an array of intensity values optionally compressed with ISO/IEC 15948 or ISO/IEC 15444 that might be cropped around the iris, with the iris at the centre, and which might incorporate region-of-interest masking of non-iris regions.

ISO/IEC 19794-6:2011 does not establish

  • requirements on the optical specifications of cameras,
  • requirements on photometric properties of iris images, or
  • requirements on enrolment processes, workflow and use of iris equipment.
