ANSI/<strong>NIST</strong>-ITL 1-<strong>2011</strong> - UPDATE 2013 DRAFT VERSIONDifferent uses may require different subsets of the features defined in this annex. Field 9.303:EFS feature set profile / FSP defines the specific sets of EFS fields. Profiles can beincorporated by reference into the definition of transactions: this decoupling of feature sets fromtransactions enables different transactions to share a common feature set, aiding ininteroperability.Automated algorithms can use the extended features defined <strong>for</strong> a latent search withoutexplic<strong>itl</strong>y computing them <strong>for</strong> the exemplar image, and thus it must be emphasized thatautomated extraction of the extended features on the exemplar is not necessarily the only nor thebest way to use this in<strong>for</strong>mation.F.4 No features present fieldsThe following table shows the correspondence between related pairs of fields. For each row inthe table, only one field shall be present in a record.For example, if there are no cores included in Field 9.320: EFS cores / COR, then Field9.325: EFS no cores present / NCOR would be set to “Y” if analysis determined that therewere no cores discernible, but would have been omitted if analysis had not been conducted <strong>for</strong>cores.Table 117: Features and Corresponding presence fieldsFeature fieldsFields indicating lack of the featureField 9.320: EFS cores / COR Field 9.325: EFS no cores present / NCORField 9.321: EFS deltas / DEL Field 9.326: EFS no deltas present / NDELField 9.324: EFS distinctive features / DIS Field 9.327: EFS no distinctive featurespresent / NDISField 9.331: EFS minutiae / MIN Field 9.334: EFS no minutiae present / NMINField 9.340: EFS dots / DOT Field 9.346: EFS no dots present / NDOTField 9.341: EFS incipient ridges / INR Field 9.347: EFS no incipient ridgespresent / NINRField 9.342: EFS creases and lineardiscontinuities / CLDField 9.348: EFS no creases or lineardiscontinuities present / NCLDField 9.343: EFS ridge edge features / REF Field 9.349: EFS no ridge edge featurespresent / NREFField 9.345: EFS pores / POR Field 9.344: EFS no pores present / NPOR486
