ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSION7.7.12.1 Type-9 extended feature set (EFS) pathsThe vertices for paths in the EFS Type-9 records are defined in a single information item 43for each of the following fields (See Table 30 Type-9 Fields for EFS). If multiple paths arepresent, they are stored within separate subfields. Each vertex is expressed as an (X,Y) pairof non-negative 44 integers in units of 10 micrometers (0.01mm).The Extended Feature Set used in the Record Type-9: Minutiae data record wasdeveloped as a separate encoding structure that has been incorporated into this standard. Inorder to avoid conflicts with systems that had already programmed using the EFS method ofspecifying paths, that structure is retained in this standard.EFS fields using closed paths, and requiring at least 3 vertices, are:• Field 9.300: EFS region of interest / ROI• Field 9.302: EFS finger - palm - plantar position / FPP• Field 9.324: EFS distinctive features / DIS• Field 9.357: EFS local quality issues / LQI• Field 9.360: EFS area of correspondence / AOCAn open path is a series of connected points in which there is not an implicit connectionbetween the last and first vertices. Within EFS, open paths are used in Field 9.373: EFSridge path segments / RPS.7.7.12.2 All other fields specifying pathsThe first information item is dependent upon the Record Type and field.• In Field 10.033: Feature contours / FEC which is an open path, the firstinformation item is the feature contour code / FCC, selected from the “Code”column of Table 18.• In Record Type-17 Fields 17.033 through 17.036, and in Field 10.015: Face imagepath coordinates in full image / FPFI the first information item is the boundarycode / BYC, with an alphabetic value selected from the “Code” column of Table 19.• For Field 10.045: Occlusions / OCC and Field 17.037: Non-eyelid occlusions /NEO, the first information item is the occlusion opacity / OCY, selected from the“Code” column of able 20.• In Field 14.025: Alternate finger segment position(s) / ASEG and Field 19.019:Friction ridge - toe segment position(s) / FSP the first information item contains afriction ridge generalized position / FGP, an integer from Table 8.43In Traditional encoding, it is entered as a single string of “x1,y1-x2,y2-…-xN,yN” where xK indicates theK th vertex, up to the total number of vertices. A comma “,” shall be entered between the X and Ycoordinates of a vertex in this string, and a dash “-“ shall be entered between coordinate pairs.44[2013e>] Error correction from first edition: postitive integers → non-negative integers [
ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSION• In Field 20.016: Segments / SEG the first information item is the referencesegment position / RSP. This provides a unique index to a segmentation. (SeeSection 7.3.2.2 for its use in Field xx.997 in other record types.)• In Field 21.016: Segments / SEG the first information item is the associatedsegment position / ASP. This provides a unique index to a segmentation. (SeeSection 7.3.3.2 for its use in Field xx.995 in other record types.).For Field 10.045, Field 17.037, Field 20.016, and Field 21.016, the second informationitem is described below.• For Field 10.045: Occlusions / OCC and Field 17.037: Non-eyelid occlusions /NEO, the second information item is the occlusion type / OCT. It is one charactercontaining a code from Table 21.• For Fields 20.016 and 21.016 only, the second information item is the internal filereference pointer/ IPT. It is set to 0 if the source representation is a single file. Ifthe external file referenced in Field 20.994: External file reference / EFR or Field21.994: External file reference / EFR is a PDF, video, or presentation file, or hasmultiple locations where a sample may be located, this information item is thereference to the particular instance, such as page, video frame, or slide number usedto derive the image transmitted in other record types. If a particular frame is chosenand there is no further image segmentation needed, the following information itemsshall not be used.The second (or third in the case of Field 10.045, Field 17.037, Field 20.016, or Field21.016 ) information item (number of points / NOP) shall specify the number of vertices.The next information items are pairs of x and y coordinates of vertices. The horizontaloffsets (X) are the pixel counts to the right, and the vertical offsets (Y) are the pixel countsdown from the origin. The first information item in this pairing is the horizontal pointoffset / HPO. The second information item in this pairing is the vertical point offset /VPO. Pairings are inserted for each vertex, up to the NOP.94
