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]. Because, when 1M prints got registered, this classification system by Henry became complex and inefficient to manage. Ridge Formation - (Ridges starts to form in the fingers and thumb during the 3rd to 4th months of the fetus life.) Comparison of average fingertip size in male and female fingerprints. Thus, FTS scores are computed individually for male (4030 samples) and female (4100 samples) of all the internal databases and shown in Table4. Fingerprint Matching Chapter 4, sections 4.4-4.8 Handbook of fingerprint recognition & . If you count the intersecting lines between these two points you should come up with 11 (plus or minus 1). The third section details the OSA method. Ridge count of at Types of fingerprint patterns.ppt - Types of fingerprint. Secondary Classification: 3. It is demonstrated that the males have a higher ridge breadth than females [1]. Ridge Feature Recognition; Ridge Counting; Charted Enlargement (Loop) Charted Enlargement (Whorl) Charted Enlargement (Arch) IMPORTANT! What are various methods available for deploying a Windows application? The following is the typical layout of a ten-digit fingerprint card. The ridge count is calculated by counting the number of ridges intervening between the delta and core [19]. In this classification, numerical values of the finger with whorl are considered. These methods calculate ridge direction directly. The singular point area is defined as a region where the ridge curvature is higher than normal and where the direction of the ridge changes rapidly [15]. View Fingerprint-reviewer.ppt from BSCRIM 123 at University of La Salette - Main - Santiago City, Isabela. Patterns: Loops and Whorls. FCM, LDA, and NN classifiers were used for gender classification. A person's fingerprints are based on the patterns of skin ridges (called dermatoglyphs) on the pads of the fingers. A maximum score of 10 is assigned for this RC. 4.UNIVERSAL: the palmer surface of the hand, finger carries the friction ridges. For this study, the RTVTR, and white lines count features were analyzed for 255 persons (150 males, and 105 females). Article (Note 9): Special Loop Extension of Fingerprint Classification-> When to Use-> How they align on Henry Line-> Procedure-> WorksheetCheck Now: Special loop extension of fingerprint With Worksheet. Thus, collectively 4030 samples were used for testing the proposed method. The fingertip size is computed in square millimeter. 4. The ridge counting of the loop and ridge tracing of the whorl pattern is consider. 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. In this manuscript, automatic gender identification from the fingerprint ridge count (RC) and fingertip size (FTS) using the OSA method is proposed. Left thumb conversion for ridge counts: 1 to 11 small (S), 12 to 16 medium (M), 17+ large (L) Right thumb: If the ridge count of the left thumb is 16 or less, the same conversion is used for the left and .

By adding a degree of bias to the regression estimates, ridge regression reduces the standard errors. The total ridge count is calculated by Eq. The software system includes digitizer, preprocessor and counter subsystems. We published on topics on fingerprints, questioned documents, forensic medicine, toxicology, physical evidence, and related case studies. But Why Not effective? o Fragments and dots are counted as ridges only if they appear as thick as the surrounding ridges.

The proposed method of gender classification is demonstrated in Fig. ALUMINIUM POWDER: The most commonly used development powder used extensively since the 1970s. In the proposed method, instead of considering counting only between the core and delta, an effort is taken to count the ridges of the entire fingertip. {\text{ of occurence of an RC}}}}{\text{Total number of samples}} \times 100.

[4] compared RTVTR, ridge count, white lines count, ridge count asymmetry and pattern type concordance as features. When multicollinearity occurs, least squares estimates are unbiased, but their variances are large so they may be far from the true value. The types of fingerprints and its singular points are illustrated in Fig. The fingertips, palms, and soles can sometimes create a transfer of these patterns when they come into contact with surfaces and objects. The low point on a ridge is called a col or saddle. Complex Intell. Major Classification: Ridge counts or trace values of loops and whorls on the thumbs.
