Why does the original fingerprint division need modification? Part of Springer Nature. Also, the traditional spectral analysis method was realized and a novel statistical method was presented for ridge distance estimation [8]. 1. Slider with three articles shown per slide. They allow individualization and classification. WCDX is an acronym for Whorl, Central Pocket, Double, and Accidental loop whorls. ridge count has often been used to increase reliability of analysis ; Ridge count is an abstract measurement of the distances between any two points in a fingerprint image ; Typically used in forensic matching ; 39 Summary of the chapter. The fingerprints were categorized into four age groups, viz., 812, 1318, 1825 and above 25. Comparing both values, gender is declared. Ridge ending and ridge bifurcation are two frequently used minutiae in most fingerprint matching algorithms. 1 Clear inspection reveals dozens of other imperfections such as ridge endings, ridge bifurcations, island ridges etc. In this manuscript, automatic gender identification from the fingerprint ridge count (RC) and fingertip size (FTS) using the OSA method is proposed.

Primary Classification A numerical system of classifying a full set of prints based on the whorl pattern. *Whorls will have a right ridge count & a left ridge count. If the male score (MS) is higher than the female score (FS), the decision is declared as male, otherwise it is declared as female. 4.UNIVERSAL: the palmer surface of the hand, finger carries the friction ridges. For the age group 1925 years, the results are good and the success rate achieved is 88.41%. Figure6 illustrates the increase in classification rate (%) from the frequency domain technique to the spatial parameters technique. . The class characteristics of fingerprints ridge patterns can be classified in three traits: Whorls, Loops, and Arches. As the scores assigned for a particular value of RC/FTS are different for male and female, the sum of these scores computed for each gender is distinguishable and thus declares more accurate results. In Henrys fingerprint classification system, there are 6 main divisions with 3 common extensions. Ridge counting-and-tracing. What are the rules in Ridge tracing? 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. Sci Mon 52(5):389402, Nithin MD, Manjunatha B, Preethi DS, Balaraj BM (2011) Gender differentiation by finger ridge count among south Indian population. It will be represented in the form of numerical fraction. These are called level 1 details. In Image #3 at the right, there is a line drawn between the delta and core. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'forensicreader_com-medrectangle-3','ezslot_1',125,'0','0'])};__ez_fad_position('div-gpt-ad-forensicreader_com-medrectangle-3-0');More precisely, these six divisions with extensions are referred to as FBI modified Henry fingerprint classification system. One of the largest, most distinguished, and innovative of the university presses today, its collection of print and online journals spans topics in the humanities and social sciences, with concentrations in sociology, musicology, history, religion, cultural and area studies, ornithology, law, and literature. For example, as in Table4, FTS=400 has its occurrence percentage as 2.8780. A white space must always intervene between the delta and the first ridge to be counted. Request Permissions, Gordon Mendenhall, Thomas Mertens and Jon Hendrix, Published By: University of California Press. A human fingerprint is the representation of dermal ridges on each fingertip. From the analysis, it is observed that the ridge count and the fingertip size of the fingerprints are more for male than female. The gender of the unknown fingerprint I is declared as male if IMS>IFS, and otherwise declared as female. Correspondence to Proportionate scores are assigned to the remaining values of the ridge count and fingertip considering the most occurring ridge count and fingertip as reference. Geometric and spectral methods were used to estimate fingerprint ridge distance [9]. The SlideShare family just got bigger. The pattern is dominated by central features, such as whorls, loops, arches and triradii. In this classification, only whorls are classified and named down based on the pattern appearing on all of the fingers. 1. Ridge counts were determined for all 8130 fingerprints of 403 male and 410 female fingerprints and analyzed. In case of right thumb, the left delta is considered. Approximately 255 of population have 1/1 value, it means all their fingers have arch or loop. A detailed analysis of RC and FTS was carried out in the previous section.

We published on topics on fingerprints, questioned documents, forensic medicine, toxicology, physical evidence, and related case studies. 4. The singular point area is defined as a region where the ridge curvature is higher than normal and where the direction of the ridge changes rapidly [15]. Do not sell or share my personal information. Comparison of FTS values is made between genders and all four age groups. The percentage occurrence of a particular FTS among total fingerprints is determined by Eq. The fingertip size is computed in square millimeter. Although the basic whorl, arch, and loop patterns may be similar, the details of the patterns are specific to each individual. The types of fingerprints and its singular points are illustrated in Fig. Ridge CountingThe process of counting the ridges that touch orcross the line of count drawn between the delta and core of loop patterns. Eur J Sci Res 59(2):191199, Samta Gupta, Prabhakar Rao A (2014) Fingerprint based gender classification using discrete wavelet transform & artificial neural network. The third section details the OSA method. These were: With this system, every finger in this world can be registered in one of the 1024 possible groups. And the process of inserting information such as appropriate numbers, letters, and symbols onto the card is known as blocking the card. CLASSIFIABLE : as the fingerprints have different patterns such as loops, whorls, and arches. She writes a part of this blog post. He was able to discover the three families of fingerprint patterns. Int J Comput Sci Issues 9(3):274282, Gnanasivam P, Muttan S (2012) Singular value decomposition based fingerprint gender classification. R. Vijayarajan. You can read the details below. The total ridge count is calculated by Eq. In doing so, you just have to place it in the numerator, and place immediately left of the major division value. The right thumb is to be the first finger. called the total ridge count (TRC), the sum of the ridge counts for all 10 fingers.

Gender classification from ridge count and fingertip size. Similarly, considering I as a female fingerprint, the total score of IFS is calculated by Eq. Fingerprint Matching Chapter 4, sections 4.4-4.8 Handbook of fingerprint recognition & . If you count the intersecting lines between these two points you should come up with 11 (plus or minus 1). Required fields are marked *. Dermal Papillae - are irregular pegs composed of delicate connective tissue protruding and forming the ridges of the skin on the fingers, palms, toes and soles of the feet. What are the tracing rules for Ridge tracing? Secondary Classification: 3. He also made his own system Ridge count of at Types of fingerprint patterns.ppt - Types of fingerprint. Ridge density in a particular space was used to classify gender using fingerprint and further demonstrated that the females have a higher ridge density compared with males. Performance evaluation was done with the methods tested and the earlier methods by other researchers. 1). They used a dataset of 400 fingerprints (200 males and 200 females) of Indian origin in the age group of 1860years. However, only one value is used to classify it in the henry classification line. The FBI have nearly 50 million of fingerprint records in its computer database but as impossible to find two fingerprints are identical of two different persons. {\text{ of occurence of an RC}}}}{\text{Total number of samples}} \times 100. Ferroprussinate was used as the developer. - 80.83.122.10. Click here to review the details. The acceptance of fingerprint evidence in the court of law based on assumption that no two individual posses the identical fingerprints. An algorithm for assigning score for each value of the parameters was discussed. If fingerprint is of the right hand, the square is placed at the upper left of the core. In addition to publishing its own journals, the division also provides traditional and digital publishing services to many client scholarly societies and associations. Ridge counts were determined for all 8130 fingerprints of 403 male and 410 female fingerprints and analyzed. Plain Arch Raised ridges characterize this pattern and they extend from one side of the finger to the other in a continuous fashion. The main reason behind this is that fingerprint is unique and unchanging through the lifetime. For loop pattern, ridge counting is done in following manner. Nutant loop: in this pattern the loop is in the appearance of sickle cell and bends near the core of the delta. Therefore, fair chances of occurrence of fingerprint in all types of crime.
