DANSK DSF/ISO/IEC FDIS 39794-6 PDF

This part of ISO/IEC 39794 specifies – 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, – examples of data record contents, – application specific requirements, recommendations, and best practices in data acquisition, and – conformance test assertions and conformance test procedures applicable to this part of ISO/IEC 39794. The iris image information is 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 39794 also specifies elements of conformance testing methodology, test assertions, and test procedures as applicable to this part of ISO/IEC 39794. It establishes test assertions pertaining to the structure of the iris image data format as specified in Clause 6, 7, 8 and 9 of this part of ISO/IEC 39794, test assertions pertaining to internal consistency by checking the types of values that may be contained within each field, and semantic test assertions. The conformance testing methodology specified in this part of ISO/IEC 39794 does not establish – tests of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, security), – tests of conformance of systems that do not produce data records conforming to the requirements of this part of ISO/IEC 39794.
