These frictions are provided during the birth to provide firm grasping and resistance to slipping. Its occurrence percentage is calculated as 4.2683 and referred to as the maximum occurrence percentage. This paper demonstrates the identification of gender using the spatial parameters of the fingerprint. Although the basic whorl, arch, and loop patterns may be similar, the details of the patterns are specific to each individual. In the Henry key classification system, you have to count the first loop that is appearing on the card except for loops on the little finger. What are the tracing rules for Ridge tracing? In the same manner as inn major division classification. In: The international conference on image processing. The percentage occurrence of a particular FTS among total fingerprints is determined by Eq. A human fingerprint is the representation of dermal ridges on each fingertip. Now, using Eq. (1). 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. 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. An extensive analysis of both parameters was done and it is found that all the values obtained are greater for male than female. (4) and tabulated in Table4.

The gender of the unknown fingerprint I is declared as male if IMS>IFS, and otherwise declared as female. A person's fingerprints are based on the patterns of skin ridges (called dermatoglyphs) on the pads of the fingers. The best results were obtained for the age group 1925 years alone compared with the earlier publications of the author in Table6. 1. For reference purpose, fingers are numbered 110 starting from left little finger to right little finger (left little finger 1, left thumb 5, right thumb 6 and right little finger 10). Check how you can easily calculate sub-secondary classification numbers easily. 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. The process of counting the ridges that touch or 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]. For an unknown fingerprint, different scores are assigned for RC and FTS for male and female. The software system includes digitizer, preprocessor and counter subsystems. The above para is the short introduction to fingerprint classification modified by the FBI. where RCM and FTSM are the respective scores of ridge count and fingertip size assigned for male fingerprints. First you must find the delta. In Henrys fingerprint classification system, there are 6 main divisions with 3 common extensions. A white space must Ridge parameters such as fingerprint ridge count, ridge density, ridge thickness to valley thickness ratio, ridge width and fingerprint pattern types are used for gender determination. A novel method of OSA technique was proposed for gender classification using the ridge count and fingertip size. The ridges make a backward turn in loops but they do not twist. This method produced a success rate of 88.41% and 90.11% is achieved for the right hand ring finger. From the results shown in Table7, it is observed that the OSA method results (age group 1925 years) are good individually for male and female. 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.

A maximum score of 10 is assigned for this RC. Fingerprints Analysis and Understanding By Hawthorne [, Advances in Fingerprint Technology by Fisher [, Fingerprint Analysis Laboratory Workbook by Daluz [Book]. It is characterized by almost parallel ridges that form distinguishable configurations. In a fingerprint card, there is a specific layout and position of each finger of the hand. The ridge features extracted are ridge count, ridge length, ridge curvature direction (concav e shape and conve x shape), and ridge type between two minutiae. Values vary from 1/1 to 32/32.2. The ridge count is calculated by counting the number of ridges intervening between the delta and core [19]. ridges only if they appear to be as thick and heavy as the other.
