ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONE.5 Number of photographsLevels 50 and 51 records mandate multiple images. However, if the subject has accessories thatocclude facial features, e.g. such as eyebrow studs, ear plugs, or rings through the nose, at leastone frontal image should be captured with them and one image without. Levels 50 and 51 shallinclude at least five photographs of the subject: (frontal, left full profile, right full profile, lefthalf profile and right half profile).Figure 22: Five poses for SAP 50 and 51Figure 23: A facial template and example of"Head and Shoulders" scene constraintsMay, 2013 DRAFT VERSION UPDATE 2013 Page 477
ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONFigure 24: Facial image template and example of "Head Only" scene constraintsE.6 Data handling requirementsE.6.1Compression algorithmE.6.1.1 SAP Levels 30 and 32 onlyThe algorithm used to compress mugshot and facial images shall conform to the JPEGSequential Baseline mode of operation as described in ISO/IEC 10918. The target size for aJPEG compressed color mugshot image file shall be 25,000 to 45,000 bytes.E.6.1.2 SAP Levels 40 and aboveNon-frontal facial images shall be compressed using JPEG 2000, as specified in ISO/IEC15444. (JPEG is not allowed). There shall be one frontal facial image compressed usinglossless JPEG 2000. If multiple frontal images are in the transaction, then one image must becompressed via lossless compression and the others can be compressed either using losslessJPEG 2000 or lossy JPEG 2000 that meets the maximum compression limits specified below.The best practice is to apply the lossless compression to the frontal image with ears visible.E.6.2Compression ratioThe maximum compression ratio for both JPEG and JPEG 2000 of a rectangular regioncontaining any exposed skin of the face, from crown to chin and ear to ear, shall be at most15:1. This requirement is derived from studies of face algorithm matching at high and lowresolutions. The non-facial portion of the mugshot, as well as other Type-10 records, can becompressed up to a ratio of 120:1.Custom JPEG source code can be created to implement compression with both ROI and fixed478
