The back-propagation neural network classifier was used to classify the gender [13] and the classification rate achieved was 92.67%. Frequency domain analysis of fingerprint [11] for the identification of gender produces a good classification rate. This friction skin consists of series of lines corresponding to hills are ridges and valleys are grooves. These can be seen in almost 60 to 70% of the fingerprints that are encountered. These ridges are also present on the toes, the palms of the hands, and the soles of the feet. Weve updated our privacy policy so that we are compliant with changing global privacy regulations and to provide you with insight into the limited ways in which we use your data. PERMANENCE: a fingerprint is permanent and unchangeable during lifetime. On the fingertips three main pattern types are discriminated: whorls, loops and arches (see Fig. A white space must always intervene between the delta and the first ridge to be counted. For example, as in Table2, RC of 25 has its occurrence percentage as 3.2195. The prints that are developed from the perspiration are the latent prints that are invisible by the naked eyes. In this section, a novel approach of the gender classification using the OSA method is compared with various methods experimented by the author [12, 20, 21].

The measured fingerprint FTSs are listed in ascending order and the number of each FTS is counted. There are three most common extensions used by the FBI to subdivide large Henry search groups. f Major Division - is placed just to the left of the primary in the classification formula. *Numerical values are assigned to each finger *If the finger has a whorl pattern, then plug that number into the primary classification equation. In the fingerprint card, the major divisions ridge count or ridge trace values are placed immediately to the left of the primary classification column. Designated by letters: for loops (S, L), and for whorls (I, O)5. Ridge Counting. The Perks of Technology in Communication.pdf. Thats why the majority of final classification is known to be only loop pattern-driven. In a fingerprint card, there is a specific layout and position of each finger of the hand. These frictions are provided during the birth to provide firm grasping and resistance to slipping. Looks like youve clipped this slide to already. where RCF and FTSF are the respective scores of ridge count and fingertip size assigned for female fingerprints. Avoid the most common mistakes and prepare your manuscript for journal Tap here to review the details. 2 What is ridge counting and how it is done? From the analysis, it is observed that the ridge count and the fingertip size of the fingerprints are more for male than female. Fingerprints and Ridge 5.

I did and I am more than satisfied. Variations in inking and pressure. 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 the future, the fingerprint data obtained in the present study, which are stored as PDF files, and the free software RIDGECOUNTER [24] can be used to analyse quantitative dermatoglyphic. The process of manual fingerprint classification always starts with primary classification. The ridge counting of the loop and ridge tracing of the whorl pattern is consider. For terms and use, please refer to our Terms and Conditions c. Ridge tracing. Thus, collectively 4030 samples were used for testing the proposed method. 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. If the whorl pattern is found on any finger of 1st pair, number 16 is assigned to it. A maximum score of 10 is assigned for this FTS. While classification, as stated earlier, these small letters appear next to the secondary capital letters. Comparison of average fingertip size in male and female fingerprints. The best results were obtained for the age group 1925 years alone compared with the earlier publications of the author in Table6. Ridge Regression is a technique for analyzing multiple regression data that suffer from multicollinearity. The average RC values of male and female (for all fingerprints of the database) are compared in the line chart shown in Fig. In this classification, only whorl and loop pattern is considered on the right and left thumb. Ridge counts were determined for all 8130 fingerprints of 403 male and 410 female fingerprints and analyzed. o If you cross a bifurcation, count each of its arms. What are various methods available for deploying a Windows application? The fingertip size is computed in square millimeter. FTS is computed using the scanner information. Secretions stick to unique ridge patterns on skin, 1902 first murder solved using fingerprints, 2007 Department of Homeland Security has 63 million records, Treated with powders or chemicals enhance ridge pattern, Prints can be formed through surgical gloves, Prints left on the inside of gloves can be lifted, Whorls occur in 25% of fingerprint patterns, IAFIS (Integrated Automated Fingerprint Identification System) can search back 99 years, Can search 47 million set of prints in 30 minutes, AFIS searches for a biometric pattern not a fingerprint!

The SlideShare family just got bigger. Fingers involve= index, middle and ring of both hands Loops ridge count I O. This backward turn or loop is distinguished by how the loop flows on the hand and not by how the loop flows on the card where the imprint is taken. If there is a loop pattern then ridge counting will be done. Comparing both values, gender is declared. 6 What are the tracing rules for Ridge tracing? In terms of age, the quality scores of 1825 age group are good [6] compared to<18 and>25 age groups. For example, as in Table4, FTS=400 has its occurrence percentage as 2.8780. Ridge counts were determined for all 8130 fingerprints of 403 male and 410 female fingerprints and analyzed. What is Ridge counting and tracing in geology? This item is part of a JSTOR Collection. Using the ridge thickness to valley thickness ratio (RTVTR) and white lines count features [4], gender was classified. Check how you can easily calculate sub-secondary classification numbers easily. It refers to the insertion on a fingerprint card the results of the interpretation of all ten. The sum of these two scores is calculated for male and female. Every criminal uses his hands for the commission of crime. As a novel method, the OSA method is proposed to classify gender. If the traced ridge ends without reaching the right side, it is necessary to drop perpendicularly to a point on a ridge directly below and continue the tracing up to the relative point nearest the right delta. 1.
