ANSI/NIST-ITL 1-2011Data Format for the Interchange of Biometric and Forensic Information19.3 Field 15.003: Impression type / IMPThis mandatory field shall be selected from Table 8, describing the manner bywhich the fingerprint image information was obtained.19.4 Field 15.004: Source agency / ORI / SRCThis mandatory ASCII field shall contain the identification of the administration ororganization that originally captured the palmprint image contained in the record.Normally, the Originating Agency Identifier, ORI, of the agency that captured theimage will be contained in this field. The SRC shall be defined by the user andbe in accordance with the receiving agency.19.5 Field 15.005: Palmprint capture date / PCDThis mandatory ASCII field shall contain the date that the palmprint imagecontained in the record was captured. See the relevant Annex in this standardfor the exact encoding format for this data. The YYYY characters shall representthe year the image was captured; the MM characters shall be the tens and unitsvalues of the month; and the DD characters shall be the tens and units values ofthe day in the month.19.6 Field 15.006: Horizontal line length / HLLThis mandatory ASCII field shall contain the number of pixels contained on asingle horizontal line of the transmitted image.19.7 Field 15.007: Vertical line length / VLLThis mandatory ASCII field shall contain the number of horizontal lines containedin the transmitted image.19.8 Field 15.008: Scale units / SLCThis mandatory ASCII field shall specify the units used to describe the imagesampling frequency (pixel density). A "1" in this field indicates pixels per inch, ora "2" indicates pixels per centimeter. A "0" in this field indicates no scale isgiven. For this case, the quotient of HPS/VPS gives the pixel aspect ratio.19.9 Field 15.009: Horizontal pixel scale / HPSThis mandatory ASCII field shall specify the integer pixel density used in thehorizontal direction of the transmitted image providing the SLC contains a "1" ora "2". Otherwise, it indicates the horizontal component of the pixel aspect ratio.19.10 Field 15.010: Vertical pixel scale / VPSThis mandatory ASCII field shall specify the integer pixel density used in thevertical direction of the transmitted image providing the SLC contains a "1" or a"2". Otherwise, it indicates the vertical component of the pixel aspect ratio.194DRAFT 2
195ANSI/NIST-ITL 1-2011Data Format for the Interchange of Biometric and Forensic Information19.11 Field 15.011: Compression algorithm / CGAThis mandatory ASCII field shall specify the algorithm used to compress thetransmitted grayscale images. An entry of "NONE" in this field indicates that thedata contained in this record is uncompressed. For those images that are to belosslessly compressed, this field shall contain the code from Table 2 to indicatethe compression method used for the palmprint images. WSQ or JPEG 10918are to be used for those images scanned or transmitted at 500 ppi and JPEG2000 for those images scanned and transmitted at ppi greater than 500. SeeSection 5.6.1. for additional information on the usage of JPEG 2000 for thecompression of friction ridge images. The domain registrar shall maintain aregistry of acceptable compression techniques and corresponding codes thatmay be used as they become available.19.12 Field 15.012: Bits per pixel / BPXThis mandatory ASCII field shall contain the number of bits used to represent apixel. This field shall contain an entry of “8” for normal grayscale values of “0” to“255”. Any entry in this field greater than “8” shall represent a grayscale pixelwith increased precision.19.13 Field 15.013: Palmprint position / PLPThis mandatory tagged field shall contain the palmprint position that matches thepalmprint image. The decimal code number corresponding to the known or mostprobable palmprint position shall be taken from Table 9 and entered as a twocharacterASCII subfield.19.14 Field 15.016: Scanned horizontal pixel scale / SHPSThis optional ASCII field shall specify the horizontal pixel density used for thescanning of the original impression providing the SLC field contains a "1" or a "2".Otherwise, it indicates the horizontal component of the pixel aspect ratio.19.15 Field 15.017: Scanned vertical pixel scale / SVPSThis optional ASCII field shall specify the vertical pixel density used for thescanning of the original impression providing the SLC field contains a "1" or a "2".Otherwise, it indicates the vertical component of the pixel aspect ratio.19.16 Field 15.020: Comment / COMThis optional ASCII field may be used to insert comments or other ASCII textinformation with the image data.19.17 Field 15.024: Palmprint quality metric / PQMThis optional ASCII field is used to specify one or more different metrics ofpalmprint image quality score data for the image stored in this record. Themeaning attributed to this metric must be defined and interpreted by the producerof the scoring algorithm or by the person or system used to assign the metric tothe palmprint image. The metric may be a predictor of AFIS matcher accuracyDRAFT 2
