ANSI/NIST-ITL 1-2011Data Format for the Interchange of Biometric and Forensic Information17 Type-13 variable-resolution latent image recordThe Type-13 record shall contain image data acquired from latent captures offingerprint, plantar or palmprint images. These images are intended to betransmitted to agencies that will automatically extract or provide humanintervention and processing to extract the desired feature information from theimages. Information regarding the scanning resolution used, the image size, andother parameters required to process the image, are recorded as tagged fieldswithin the record.MnemonicCondcode*FieldnumberCharacterTypeTable 66 Type-13 RecordField nameMinOccur countMaxBrad Wing 6/21/10 10:08 AMComment: Table now included in recorddescription; with subfields and information itemsM 13.001 RECORD HEADER 1 1IDC M 13.002 N IMAGE DESIGNATION CHARACTER 1 1IMP M 13.003 N IMPRESSION TYPE 1 1SRC M 13.004 AN SOURCE AGENCY / ORI 1 1LCD M 13.005 N PLATENT CAPTURE DATE 1 1HLL M 13.006 N HORIZONTAL LINE LENGTH 1 1VLL M 13.007 N VERTICAL LINE LENGTH 1 1SLC M 13.008 N SCALE UNITS 1 1HPS M 13.009 N HORIZONTAL PIXEL SCALE 1 1VPS M 13.010 N VERTICAL PIXEL SCALE 1 1CGA M 13.011 AN COMPRESSION ALGORITHM 1 1BPX M 13.012 N BITS PER PIXEL 1 1FGP M 13.013 N FRICTION RIDGE POSITION 1 UnlimitedSPD C-FGP 13.014 SEARCH POSITION DESCRIPTORS 1 9Brad Wing 6/21/10 10:15 AMComment: Note change on upper limitFGP M⇑ N FINGER RIDGE POSITION CODE 1 1SLC M⇑ N PORTION OF EJI OR TIP IMAGE TO SEARCH 1 1PPC C-FGP 13.015 PRINT POSITION COORDINATES 1 12FVC M⇑ N FULL FINGER VIEW CODE 1 1SLC M⇑ N LOCATION OF SEGMENT 1 1LHC M⇑ N LEFT HORIZONTAL COORDINATE 1 1RHC M⇑ N RIGHT HORIZONTAL COORDINATE 1 1TVC M⇑ N TOP VERTICAL COORDINATE 1 1170DRAFT 2
