Gender classification from fingerprint ridge count and fingertip size The number, relative location and identity of the characteristics impart individuality to a fingerprint. Distance The ridge count Relative orientation of each surrounding minutiae with the central one. Friction Skin -Skin that covers the inside surface of the hands and fingers and the bottom of the feet and toes. Thus, collectively 4030 samples were used for testing the proposed method. While the second-sub secondary, WCDX and special loop division are three extensions. Ridge Characteristics Must match in two fingerprints in order for their common origin to be established No set limit on how many minutiae must match has been set However, courts will accept 8-12 points of similarity Also known as minutiae Includes Ridge ending Short ridge Dot or fragment Bifurcation Double bifurcation 4.UNIVERSAL: the palmer surface of the hand, finger carries the friction ridges.

According to them, the females fingerprint is characterized by a high RTVTR, while the males fingerprint is characterized by low RTVTR. An internal database consisting of fingerprints of 403 males and 410 females is used to test the method. An algorithm for assigning score for each value of the parameters was discussed. [Worksheet] Major Classification of Fingerprint: Calculation & Rules 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 above para is the short introduction to fingerprint classification modified by the FBI. The best results were obtained for the age group 1925 years alone compared with the earlier publications of the author in Table6. The percentage of occurrence of a particular RC among total fingerprints is determined by Eq. A ridge-based coordinate system in . It is a special extension majorly used to classify the large groups of whorls patterns such as 32/32. 1). 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]. For example. Scores for the remaining FTS are determined by Eq. [4], and the proposed method (age group of 1925). Required fields are marked *. Adjacent finger numbers of opposite hands are followed by an addition of 5. Information on the gender of a person plays a vital role in crime investigation, authentication and statistical report on the visitors. The process of manual fingerprint classification always starts with primary classification. Ridge patterns exhibit many properties that reflect the biology of individuals. In case of double loop, the ascending core is taken as constant for ridge counting and descending core will not be considered. EURSIP J Appl Sig Process 4:495502, Acree AM (1999) Is there a gender difference in fingerprint ridge density. Activate your 30 day free trialto continue reading. If the ridge count is between. 5. Every criminal uses his hands for the commission of crime. These fingerprints were divided equally for training and testing with SVM classifier. If the pattern is a loop, ridge counting is obtained. b. Ridge counting. 6 What are the tracing rules for Ridge tracing? The pattern on the right is taken as numerator and the left are taken as denominator. (5). Monika Sethi, Munish Kumar & M. K.

A delta point is a place where a ridge is bifurcated (or) a delta point is a place where two ridges run side by side and diverge [19]. From Table4, it is concluded that the FTS of 450mm2 and 530mm2 are occurring more for female and male, respectively. These methods calculate ridge direction directly. An extensive analysis of both parameters was done and it is found that all the values obtained are greater for male than female. 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.
