This document specifies:<\/p>\n
\u2014 generic extensible data interchange formats for the representation of iris image data: a tagged binary data format based on an extensible specification in ASN.1 and a textual data format based on an XML schema definition that are both capable of holding the same information,<\/p>\n
\u2014 examples of data record contents,<\/p>\n
\u2014 application specific requirements, recommendations, and best practices in data acquisition, and<\/p>\n
\u2014 conformance test assertions and conformance test procedures applicable to this document.<\/p>\n
The iris image information is stored as:<\/p>\n
\u2014 an array of intensity values optionally compressed with ISO\/IEC 15948 or ISO\/IEC 15444-1, or<\/p>\n
\u2014 an array of intensity values optionally compressed with ISO\/IEC 15948 or ISO\/IEC 15444-1 that can be cropped around the iris, with the iris at the centre, and which can incorporate region-of-interest masking of non-iris regions.<\/p>\n
This document also specifies elements of conformance testing methodology, test assertions, and test procedures, as applicable to this document.<\/p>\n
It establishes:<\/p>\n
\u2014 test assertions pertaining to the structure of the iris image data format, as specified in Clauses 6, 7, 8 and 9 of this document,<\/p>\n
\u2014 test assertions pertaining to internal consistency by checking the types of values that may be contained within each field, and<\/p>\n
\u2014 semantic test assertions.<\/p>\n
The conformance testing methodology specified in this document does not establish:<\/p>\n
\u2014 tests of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, security), or<\/p>\n
\u2014 tests of conformance of systems that do not produce data records conforming to the requirements of this document.<\/p>\n
This document does not establish:<\/p>\n
\u2014 requirements on the optical specifications of cameras, or<\/p>\n
\u2014 requirements on photometric properties of iris images, or<\/p>\n
\u2014 requirements on enrolment processes, workflow and use of iris equipment.<\/p>\n","protected":false},"excerpt":{"rendered":"
