ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSION8.9.5.8 Field 9.133: M1 finger view / FVWThis mandatory field contains the view number of the finger associated with this record’sdata. The view number begins with “0” and increments by one to “15”. Finger viewdifferentiates multiple images of the same finger that are included in the transaction to betaken consecutively to develop an "average" template for that particular set of finger minutiaefor enrollment applications.8.9.5.9 Field 9.134: M1 friction ridge generalized position / FGPThis is a mandatory field. See Section 7.7.4.2 for details . Valid codes for this field arebetween 1 and 10, taken from Table 8 to indicate the finger position. (Note that codes 16and 17 are not covered in INCITS 378). The 2007 version restricted this to fingerprint codes.The 2008 version also allowed palm codes, but this version of the ANSI/NIST-ITL standarddoes not in order to maintain consistency with INCITS 378.8.9.5.10 Field 9.135: M1 friction ridge quality data / FQDThis mandatory field shall contain the quality of the overall finger minutiae data. There maybe a subfield for each algorithm and predictive performance measure. Each subfield shallcontain the first information item (quality value / QVU) described in Section 7.7.7. Thesecond two information items are optional for this field. (algorithm vendor identification /QAV and algorithm product identification / QAP).The 2004 version of INCITS 378 had only 1 byte for quality with no second and thirdinformation items. The 2009 version of INCITS 378 had all three information items and allthree are mandatory in that standard. The 2007 and 2008 versions of ANSI/NIST-ITLmandated the presence of all three information items. However, this version of ANSI/NIST-ITL allows the second and third items to be optional, in order to accommodate those usersfollowing the 2004 version of INCITS 378.8.9.5.11 Field 9.136: M1 number of minutiae / NOMThis mandatory field shall contain a count of the number of minutiae recorded in this block.8.9.5.12 Field 9.137: M1 finger minutiae data / FMDThe total number of subfields shall agree with the count found in Field 9.136: M1 numberof minutiae / NOM. Each subfield has six information items.• The first information item (minutia index number / MAN), shall be initialized to“1” and incremented by “1” for each additional minutia in the fingerprint.• The second information item (‘x’ coordinate / MXC) is expressed in pixel units.• The third information item (‘y’ coordinate / MYC) is expressed in pixel units.• The fourth information item (minutia angle / MAV) is recorded in units of twodegrees. This value shall be nonnegative between 0 and 179, inclusive.• The fifth information (minutia type / M1M) has a value of “0” to represent aMay, 2013 DRAFT VERSION UPDATE 2013 Page 139
ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONminutia 77 of type “OTHER”, a value of “1” for a ridge ending and a value of “2” fora ridge bifurcation.• The sixth information item (quality of minutia / QOM) shall range from 1 as aminimum to 100 as a maximum. A value of “0” indicates that no quality value isavailable. Note that this is an integer.8.9.5.13 Field 9.138: M1 ridge count information / RCThis optional field shall consist of subfields of three information items. It can only appear ifa value of '514' or '515' is entered in CFT of Field 9.126: M1 CBEFF information / CBI.For the first subfield:• The first information item (ridge count extraction method / REM) shall have avalue of 0, 1 or 2. A “0” indicates that no assumption shall be made about themethod used to extract ridge counts, nor their order in the record. A “1” indicatesthat for each center minutiae, ridge count data was extracted to the nearestneighboring minutiae in four quadrants, and ridge counts for each center minutia arelisted together. A “2” indicates that for each center minutiae, ridge count data wasextracted to the nearest neighboring minutiae in eight octants, and ridge counts foreach center minutia are listed together.• The remaining two information items (filler 1 / FI1 and filler 2 / FI2) of this firstrepeating subfield shall each contain “0”.Subsequent subfields have three information items each:• The first information item (center minutia index / CMI) is a positive integer.• The second information item (neighboring minutia index / NMN) is a positiveinteger. It shall not be equal to CMI.• The third information (number of ridges crossed / NRC) is a positive integer.8.9.5.14 Field 9.139: M1 core information / CINThis optional field shall consist of one subfield for each core present in the original image.It can only appear if a value of '514' or '515' is entered in CFT of Field 9.126: M1 CBEFFinformation / CBI. Each subfield consists of three information items.• The first item (‘x’ coordinate / XCC) is an integer in pixel units.• The second item (‘y’ coordinate / YCC) is an integer in pixel units.• The third information item (angle of the core / ANGC) is recorded in units of twodegrees. The value shall be between 0 and 179, inclusive.77[2013e>] Corrected typographical error [
