As 60-65% percent of population have loops, 30-355 have whorls, about 5% have arches. Values vary from 1/1 to 32/32.2. Geometric and spectral methods were used to estimate fingerprint ridge distance [9]. If the right middle and left index contains whorl pattern and other fingers contains loops then the primary classification would be: In this classification 1 is added to both numerator and denominator is according to the pigeon system. The prints that are developed from the perspiration are the latent prints that are invisible by the naked eyes. In 1896, Sir Edward Richard Henry developed a fingerprint classification system that uses all fingerprints (hence, also called a 10-digit system). For example, as in Table4, FTS=400 has its occurrence percentage as 2.8780. PERMANENCE: a fingerprint is permanent and unchangeable during lifetime.

For Sci Int 102(1):3544, Hong L, Wan Y, Jain A (1998) Fingerprint image enhancement: algorithm and performance evaluation. In a fingerprint card, there is a specific layout and position of each finger of the hand. From Table4, it is clarified that the fingertip size of 450mm2 was found 175 times among the 4100 female fingerprints. We published on topics on fingerprints, questioned documents, forensic medicine, toxicology, physical evidence, and related case studies. The class characteristics of fingerprints ridge patterns can be classified in three traits: Whorls, Loops, and Arches. These frictions are provided during the birth to provide firm grasping and resistance to slipping. This pattern makes up a mere 5% of the total population, making it the rarest type. The program yields semi-automated ridge counts and logs the location of the user-selected core and delta points to aid in the training of new researchers and ensure the repeatability of count. If the intervening ridges moves inside and towards the right delta and ridges are between >3 inner whorl, And if move towards outside of the delta and between >3- outer whorl. Scores for the remaining FTS are determined by Eq. With respect to core and delta, RCs are determined (traditional method) and in addition, ridge counts measured diagonally (at 45 and 135) with respect to the core points are averaged.
