scope:

This part of ISO/IEC 19794 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. This part of ISO/IEC 19794 does not establish - requirements on the optical specifications of cameras, or - requirements on photometric properties of iris images, or - requirements on enrolment processes, workflow and use of iris equipment.
