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. It is demonstrated that the males have a higher ridge breadth than females [1]. A ridge is a line of high ground, with the land dropping away on either side. 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.

Finger ridge count (an index of the size of the fingerprint pattern) has been used as a model trait for the study of human quantitative genetics for over 80 years. In this sub-division classification system, the patterns present in the index, middle, and ring fingers are considered and symbolized by the specific ridge counting and ridge tracing values.Know how second sub-secondary values are calculated.

[4], and the proposed method (age group of 1925). Nutant loop: in this pattern the loop is in the appearance of sickle cell and bends near the core of the delta. The ulnar loop has 2 patterns: The final classification is made by recording the ridge counting of the loop and ridge tracing of the whorl pattern on the little finger. Ridge counting-and-tracing.

PDF Fingerprint Distribution Patterns and Ridge Counts What is ridge counting and how it is done? Although the basic whorl, arch, and loop patterns may be similar, the details of the patterns are specific to each individual. Fingerprint is an impression made by the friction ridges that are almost parallel at constant crest to crest wavelength. From the above 10-digit fingerprint card, the common interpretation is: All the fingerprints are patent on their respective position on the fingerprint card. To enable this, an imaginary line is drawn between core and delta at 135 (referred to as the principal diagonal) and 45 (referred to as the other diagonal) as shown in Fig. The ridge counting of the whorls in the final classification is very rarely used. In this classification, only whorl and loop pattern is considered on the right and left thumb. If there is whorl pattern found on the thumb then ridge tracing will be done. If the whorl pattern is found on any finger of 1st pair, number 16 is assigned to it. Estimation of ridge count. In Henrys fingerprint classification system, there are 6 main divisions with 3 common extensions. Considering I as the male fingerprint, the total score IMS is calculated by Eq. These frictions are provided during the birth to provide firm grasping and resistance to slipping. In the FBI modified version, the classification system consists of 6 main sub-classifications.

We published on topics on fingerprints, questioned documents, forensic medicine, toxicology, physical evidence, and related case studies. present on the index, middle, and ring fingers. Biometric Fingerprint Verification System Based on BFS using Ridge Features. In doing so, you just have to place it in the numerator, and place immediately left of the major division value. The average fingerprints have as many as 150 ridge characteristics. where RCM and FTSM are the respective scores of ridge count and fingertip size assigned for male fingerprints. Frequency domain analysis of fingerprint [11] for the identification of gender produces a good classification rate. Verma and Agarwal [22] used ridge density and ridge width in addition to RTVTR as features and with the SVM classifier, the results obtained by them are shown in Table7.
