ANSI/NIST-ITL 1-2011Data Format for the Interchange of Biometric and Forensic Informationnominal transmitting resolutionThe number of pixels per unit distance (ppmm or ppi) of the transmitted image.The transmitting resolution may be the same as the scanning resolution for aparticular image. On the other hand, the transmitting resolution may be less thanthe scanning resolution if the scanned image was subsampled, scaled, orinterpolated down before transmission.NFIQAbbreviation for NIST Fingerprint Image Quality.palmprintAn exemplar or latent friction ridge image from the palm (side and underside) ofthe hand. A full palmprint includes the area from the wrist to the tips of thefingers. A lower palmprint includes the area from the wrist to the base of thefingers, including the entire interdigital area. An upper palmprint includes the areafrom the tips of the fingers to the interdigital area, and must include enough of theinterdigital area to be able to determine that upper and lower palm images arefrom the same hand.palmarHaving to do with the friction ridge skin on the hands (fingers).plain fingerprintA fingerprint image resulting from the touching of one or more fingers to alivescan platen or paper fingerprint card without any rolling motion.plantarHaving to do with the friction ridge skin on the feet (soles and toes).ppiAbbreviation for pixels per inch.ppmmAbbreviation for pixels per millimeter.proximal segmentThe segment of the finger or thumb closest to the palm.recurving ridgeA ridge whose path begins in one direction, curves and continues in a pathparallel or nearly parallel to its start.An innermost recurving ridge is a recurving ridge that encloses no otherrecurving ridges.265DRAFT 2
