ANSI/NIST-ITL 1-2011Data Format for the Interchange of Biometric and Forensic InformationRGBAbbreviation for Red, Green, Blue used to represent color pixels comprised of aspecified number of bits to represent each of these primary color components.ridgeA raised portion of the epidermis on the palmar or plantar skin, consisting of oneor more connected ridge units of friction ridge skin.ridge segmentA section of a ridge that connects two minutiae; a single non-intersecting portionof a skeletonized image.ridge tracingSee skeletonized image.ridge unitA portion of a ridge that contains one pore.ROIAbbreviation for region of interest.rolled fingerprintA fingerprint image collected by rolling the finger across a livescan platen orpaper fingerprint card from nail to nail. Rolls may be from livescan devices orscanned from paper fingerprint cards.SAPAbbreviation for Subject Acquisition Profile. It is a series of sets of progressivelymore stringent parameters and requirements relevant to a device and modality.skeletonized imageA representation of a friction skin image in which all pixels are white except for a1-pixel-wide thinned black skeleton following the midpoint of each ridge. Alsoknown as a ridge tracing.slap fingerprintSlap fingerprints (slaps) are taken by simultaneously pressing the four fingers ofone hand onto a scanner or fingerprint card. Slaps are also known as four-fingersimultaneous plain impressions.SMTAbbreviation used for scar, mark, and tattoo information.266DRAFT 2
ANSI/NIST-ITL 1-2011Data Format for the Interchange of Biometric and Forensic Informationscanning resolutionInformally, the number of pixels per unit distance at which an image is captured(ppmm or ppi). More formally, “resolution” (resolving power) is distinct from“sampling frequency” (number of pixels per unit distance). Resolution can becharacterized by a measurement of the Spatial Frequency Response (SFR)function. The capture of high quality friction ridge images generally requires animage quality specification, such as the FBI’s IAFIS Image Quality Specification(EFTS Appendix F) or Image Quality Specifications for Single Finger CaptureDevices (PIV), which defines both resolution and sampling frequency. Withoutsuch a specification, the term “resolution” is only informational.substrateSurface upon which a friction ridge impression is deposited.recordA record containing unique ASCII field identifiers for variable-length data fieldsthat is capable of being parsed based on the field identifier and the data contentsof each field.transactionA command, message, or an input record that explicitly or implicitly calls for aprocessing action. Information contained in a transaction shall be applicable to asingle subject.valleyA lowered portion of the epidermis on the palmar or plantar skin, consisting ofthose areas between ridges.W3CAbbreviation for the World Wide Web Consortium. It is an internationalcommunity that develops standards for web development.267DRAFT 2
