Int J Comput Sci Issues 9(3):274282, Gnanasivam P, Muttan S (2012) Singular value decomposition based fingerprint gender classification. Not only by theoretical calculation, this principle was verified by the millions of individual who have had their fingerprint classified during the past years,. The following is the typical layout of a ten-digit fingerprint card. how to calculate it? Designated by letters: for loops (S, L), and for whorls (I, O)5. The individuality of fingerprint is not based on its pattern or shape, but it is based on the ridges characteristics called as minutiae. Syst. The fingerprints are the friction ridges that are developed on the palm side of thumb and fingers. Ridge Counting . For the plain arch, for calculation purpose, a point in a ridge which has a high peak is chosen as core and a point in the bottom-most ridge, which is almost straight, is chosen as a delta point.

The scanned image is of the size 300 260. . PubMedGoogle Scholar. If there is whorl pattern found on the thumb then ridge tracing will be done. The percentage occurrence of a particular FTS among total fingerprints is determined by Eq. In addition, the most common RC differs between male and female. Major Classification: Ridge counts or trace values of loops and whorls on the thumbs. Why does the original fingerprint division need modification? . It is used when the sub secondary classification ridge counting and ridge tracing is done and is based on the ulnar loop, composites, whorls, accidental and double loop is present in the middle and ring fingers. Secondary Classification: 3. This paper demonstrates the identification of gender using the spatial parameters of the fingerprint. The ridges make a backward turn in loops but they do not twist. Simply click, and the calculator will do the rest. Also, the traditional spectral analysis method was realized and a novel statistical method was presented for ridge distance estimation [8]. Ridge parameters such as fingerprint ridge count, ridge density, ridge thickness to valley thickness ratio, ridge width and fingerprint pattern types are used for gender determination.

All 10 fingers of each subject were scanned and thus in total, 8130 fingerprints were used. Accessed Nov 2018, Gnanasivam P, Muttan S (2012) Fingerprint gender classification using wavelet transform and singular value decomposition. To enable this, an imaginary line is drawn between core and delta at 135 (referred to as the principal diagonal) and 45 (referred to as the other diagonal) as shown in Fig. This is the highest occurrence in comparison with other RC counts. Scores for the remaining RC are determined by Eq. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'forensicreader_com-narrow-sky-1','ezslot_12',133,'0','0'])};__ez_fad_position('div-gpt-ad-forensicreader_com-narrow-sky-1-0');The right-hand finger counting value is placed in the numerator and the left hand is the denominator. The fraction thus obtained is the primary classification of fingerprint.

The total ridge count is calculated by Eq. Finger ridge count (an index of the size of the fingerprint pattern) has been used as a model trait for the study of human quantitative genetics for over 80 years. In this classification, the little fingers of both hands are employed, and ridge counting is performed on loops and whorls patterns. The measured fingerprint FTSs are listed in ascending order and the number of each FTS is counted. The ridge counting of the whorls in the final classification is very rarely used.
