Fingerprint Patterns and Ridge Characteristics There are three main types of fingerprint patterns with several subgroups of patterns: 1. Friction ridges or papillary ridges Elevated strips of skin that begin as raised apertures around the pores and then are joined together into rows forming the ridges. 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]. In this section, singular points detection, ridge count and fingertip size measurements are elaborated. Measured fingerprint RCs are listed in an ascending order and the number of each RC is counted. Google Scholar, Yin Y, Tian J, Yang X (2004) Ridge distance estimation in fingerprint images: algorithm and performance evaluation. For example. Primary, major, secondary, sub secondary, final, and key classification are the six main classifications. 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. 1. Thus, they leave fingerprints at the crime scene or an object he touches. {\text{ of occurence of an FTS}}}}{\text{Total number of samples}} \times 100.

Ridge ending and ridge bifurcation are two frequently used minutiae in most fingerprint matching algorithms. 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. o If the delta is on the only loop, there is no ridge count. Fingers involve= index, middle and ring of both hands Loops ridge count I O. From Table2, it is clarified that the ridge count of 31 was found to be 287 times among the 4100 female fingerprints. . called the total ridge count (TRC), the sum of the ridge counts for all 10 fingers. This method produced a success rate of 88.41% and 90.11% is achieved for the right hand ring finger. Principles of Fingerprint Analysis.
