Also, all these values differ for male and female in all the age groups. The types of fingerprints and its singular points are illustrated in Fig. Nutant loop: in this pattern the loop is in the appearance of sickle cell and bends near the core of the delta. A ridge is a line of high ground, with the land dropping away on either side. Table7 shows only the overall classification rate obtained by Badawi et al. Using Bayes theorem [3] on the rolled fingerprint images belonging to the South Indian population, it is found that the fingerprint possessing ridge density<13 ridges/25mm2 is most likely to be of male and ridge count>14 ridges/25mm2 are most likely to be of female. Scores for the remaining RC are determined by Eq. Check how you can easily calculate sub-secondary classification numbers easily. PPT - FINGERPRINTS PowerPoint Presentation, free download - ID:6912383 UNIQUENESS: the fingerprint is unique. Secondary classification=U/U, subsecondary= UUU/UUU; and other classification values governed by respective ridge counts. Its occurrence percentage is calculated as 4.2683 and referred to as the maximum occurrence percentage. Holt (1968) found that the average TRC for males is 145 and for females, 126. For example. Performance evaluation was done with the methods tested and the earlier methods by other researchers. The primary classification values caries from 1/1 to 32/32. Clipping is a handy way to collect important slides you want to go back to later. A white space must always intervene between the delta and the first ridge to be counted.

Fingerprint Analysis: Principles - Forensic Science Simplified Sub Secondary Classification: Ridge count or trace of the index, middle, and ring finger. A ridge count between any two points on the fingerprint is defined as the number of ridges running between the two points on the fingerprint. In this classification, the little fingers of both hands are employed, and ridge counting is performed on loops and whorls patterns. In this the pattern on it is represented by capital letter, the right index in the numerator and left index in the denominator. Fingerprints are unique patterns, made by friction ridges (raised) and furrows (recessed), which appear on the pads of the fingers and thumbs.

The main reason behind this is that fingerprint is unique and unchanging through the lifetime. Ridge Regression is a technique for analyzing multiple regression data that suffer from multicollinearity. 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. Similarly, considering I as a female fingerprint, the total score of IFS is calculated by Eq. The percentage of occurrence of a particular RC among total fingerprints is determined by Eq. The value of the special loop extension is brought by ridge count values of the index, middle and ring finger (sometimes left little finger) of both hands.

(4) and tabulated in Table4. Using the ridge thickness to valley thickness ratio (RTVTR) and white lines count features [4], gender was classified. An algorithm for assigning score for each value of the parameters was discussed. A ridge is a line of high ground, with the land dropping away on either side. chemistry. the recurve is included in the ridge count only when the delta is located below a line drawn at right angles to the spike.
