Project 1623 - ISO/IEC 19794-6:2005, Information technology
- Biometric data interchange formats - Part 6: Iris image data
Scope
This part of ISO/IEC 19794 specifies two alternative image interchange
formats for biometric authentication
systems that utilize iris recognition.
The first is based on a rectilinear image storage format that may be a
raw, uncompressed array of intensity values or
a compressed format such as that specified by ISO/IEC 15444.
The second format is based on a polar image specification that requires
certain pre-processing and image
segmentation steps, but produces a much more compact data structure
that contains only iris information.
Data that comply with either one of the iris image formats specified in
this part of ISO/IEC 19794 are
intended to be embedded in a CBEFF-compliant structure in the CBEFF
Biometric Data Block (BDB) as specified
in ISO/IEC 19785-1.
