ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSION8.17.28 Field 17.030: Device monitoring mode / DMMThis is an optional field. See Section 7.7.1.3 for details.8.17.29 Field 17.031: Subject acquisition profile – iris / IAPThis optional field lists the IAP level associated with the iris acquisition device. SeeSection 7.7.5.3 for details.8.17.30 Field 17.032: Iris storage format / ISFThis optional field, when used, shall indicate the storage format of the iris image 172 .ISF = 1 ISF = 2ISF = 3 ISF = 7Figure 19: Examples of ISF image formatsThe codes are shown in Figure 19 and Table 91. The value shall be a single digitcorresponding to the column “ISF code”. Image storage formats 1 and 2 might be thenative output of an iris camera. ISF format code 1 is designated for high resolutionoutputs. ISF level 2 is the format output in most commercial iris acquisition systems andcorresponds to the dimensions of the Video Graphics Array (VGA). Image storageformats 3 and 7 are typically prepared by client software: ISF 3 images are cropped; andISF 7 images are both cropped and masked. These operations, used in conjunction with172This is a new field with the 2011 of the standard. All new applications should use this field.May, 2013 DRAFT VERSION UPDATE 2013 Page 357
ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONthe standardized compression schemes, afford reduced record sizes. All of the formatsestablish geometric specifications. For ISF = 1 and 2, there are minimum marginrequirements specified in terms of the estimated iris radius, R (see Table 91). For ISF =3 and 7, there are exact margin requirements. These requirements support accuratelocalization of the iris boundaries.Figure 20: Iris margin specificationISF codeTable 91 Iris storage formatsDescriptionIrisCenteringIris margin requirement(R is radius of the iris)Horizontal Vertical1 Unconstrained image size Recommended ≥ 0.6R ≥ 0.2R2 Raw: 640x480 Recommended ≥ 0.6R ≥ 0.2R3 Cropped Required = 0.6R = 0.2R7 Cropped and Masked Required = 0.6R = 0.2R8.17.31 Field 17.033: Iris pupil boundary / IPBThis optional field defines the pupillary boundary, between the iris and pupil. See Section7.7.12 for a description of encoding paths.8.17.32 Field 17.034: Iris sclera boundary / ISBThis optional field defines the limbic boundary, between the iris and sclera. See Section7.7.12 for a description of encoding paths.8.17.33 Field 17.035: Upper eyelid boundary / UEBThis optional field defines the boundary between the upper eyelid and the eye. SeeSection 7.7.12 for a description of encoding paths. This is an open path.358
