ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSION7.7.5.1.1 Level 0 (Unknown profile)This level denotes any case when the SAP is unknown. This value may be used to alertsystems that the profile of the face image needs to be determined manually or viaadvanced face image quality evaluation techniques.7.7.5.1.2 Level 1 (Surveillance facial image)This SAP value denotes a surveillance facial image: a face image captured withoutspecific regard to scene, photographic, or digital requirements. For example, an image ofa face from commonly available surveillance video equipment is generally considered asurveillance facial image. Typically surveillance facial images are of relatively poorquality compared to mugshots, including significant pose angle used for the frontal view,poor image resolution, poor image contrast, etc.7.7.5.1.3 Levels 10-15 (Other application profiles)Levels 10-15 shall denote transaction associated with capture under the guidance of otherfacial standards or application profiles as defined below. Note that the facial images ofLevel-13 and Level-14 may come from travel documents as described in “Deployment ofMachine Readable Travel Documents’’, ICAO Technical Report, version 2.0.• Level-10 denotes a driver license facial portrait described in the AAMVAInternational Specification – DL/ID Card Design.• Level-11 denotes an ANSI facial image that meets requirements of the Full FrontalImage type defined in ANSI INCITS 385-2004.• Level-13 denotes an ISO facial image that meets the requirements of the FullFrontal Image defined in International standard ISO/IEC 19794-5• Level-14 denotes an ISO facial image that meets the requirements of the Token FaceImage type defined in International standard ISO/IEC 19794-5.• Level-15 denotes a PIV facial image that meets requirements of Biometric DataSpecification for Personal Identity Verification defined in NIST SP 800-76.See Section 3 Normative references for information about the references cited above.7.7.5.1.4 Level 20 (Legacy mugshot)A facial image conforming to this application profile level shall be a mugshot formattedaccording to ANSI/NIST-ITL 1-2000, but not necessarily conforming to the best practicerequirements given in level-30. The subject pose(s) may be Frontal, Profile, or Angled.May, 2013 DRAFT VERSION UPDATE 2013 Page 73

ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSION7.7.5.1.5 Level 30 (Basic mugshot)These mugshots shall adhere to strict background, lighting, and resolution requirements.In particular, the background is 18% gray, the lighting is three-point, and the image size isat least 480 x 600 pixels with an aspect ratio of 1:1.25. Annex E: Facial Capture –SAPs 30 and above for more information about Level 30.7.7.5.1.6 Level 32 (Mobile device basic mugshot)The requirements for level 32 are based on those of level 30, but not fully inclusive of allof those requirements. For instance, relative centering error and 18% grayscale withappropriate lighting may not be realistic for a mobile application. Use of this SAPnumber indicates that the image was captured with a mobile device. See Table 11 for thecomplete requirements for SAP level 32.7.7.5.1.7 Level 40 (Higher resolution mugshot)A facial image conforming to the level-40 application profile can be captured with an offthe-shelf1-megapixel camera. Requirements for conformance with level-40 facial imagecapture include the following (See Annex E: Facial Capture – SAPs 30 and above):· The image shall conform to the minimum requirements for the capture of level-30facial images· At least one full frontal face image shall be captured.· The minimum number of pixels in the digital image shall be 768 x 1024 pixels, and· Facial images shall conform to the “head and shoulders” composition detailedrequirements shown in Annex E: Facial Capture – SAPs 30 and above.It should be noted that the resolution aspect of the captured facial images are improved asthe number of pixels in both directions are increased. As images are captured with anincreased number of pixels, the 3:4 (Width : Height) aspect ratio shall be maintained.7.7.5.1.8 Level 42 (Mobile device higher resolution mugshot)The requirements for level 42 are based on those of level 40, but not fully inclusive ofthose requirements. For instance, relative centering error and 18% grayscale withappropriate lighting may not be realistic for a mobile application. Use of this SAPnumber indicates that the image was captured with a mobile device. See Table 11 for thecomplete requirements for SAP level 42.7.7.5.1.9 Levels 50 and 51 (Best practice mugshots)A facial image conforming to the level 50 and level 51 application profiles shall include“face image capture requirements”. See Annex E: Facial Capture – SAPs 30 andabove. These profile levels are intended to allow for examination of up to forensic-level74
