Anotace textu normy ISO/IEC 19794-6-ed.2.0 :

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.
