A white space mustalways intervene between the delta and the first ridge to be counted. Therefore, fair chances of occurrence of fingerprint in all types of crime. The pattern on the right is taken as numerator and the left are taken as denominator. To match a print, the analyst uses the minutiae, or ridge characteristics, to identify specific points on a suspect fingerprint with the same information in a . And the process of inserting information such as appropriate numbers, letters, and symbols onto the card is known as blocking the card. Invaded loop: the ridge passing over the pattern coming from the direction of the delta or trying to engulf the loop. In this classification, the little fingers of both hands are employed, and ridge counting is performed on loops and whorls patterns. For the age group 1925 years, the results are good and the success rate achieved is 88.41%. This pattern makes up a mere 5% of the total population, making it the rarest type. For this study, the RTVTR, and white lines count features were analyzed for 255 persons (150 males, and 105 females).

Each issue features reviews of books, classroom technology products, and "Biology Today." These three patterns helps to classify the prints in all ten fingerprint classification. If the traced ridge ends without reaching the right side, it is necessary to drop perpendicularly to a point on a ridge directly below and continue the tracing up to the relative point nearest the right delta. Variations in ridge parameters for male and female are found statistically [1, 2]. No two individual posses same ridge characteristics. Here, a maximum score of 10 is assigned for each RC. Frequency domain analysis of fingerprint [11] for the identification of gender produces a good classification rate. To improve the success rate further, other fingerprint features can also be included. 4.UNIVERSAL: the palmer surface of the hand, finger carries the friction ridges. These ridges are also present on the toes, the palms of the hands, and the soles of the feet. AGREEMENT: The ridge flow, characteristics and / or details appear in the same relative position with the same intervening ridge count, allowing for explainable differences, so to enable the practitioner to reach their conclusion. Fingerprint is an impression made by the friction ridges that are almost parallel at constant crest to crest wavelength. The ridge count is calculated by counting the number of ridges intervening between the delta and core [19].

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. 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 . As 60-65% percent of population have loops, 30-355 have whorls, about 5% have arches. [4] compared RTVTR, ridge count, white lines count, ridge count asymmetry and pattern type concordance as features. Like others, ridge counting values of the right hand are placed in the numerator and left hand in the denominator. $$, $$ {\text{RC score }} = \, \frac{{{\text{Occurrence \% of a particular RC}}}}{{{\text{Maximum occurence \% }}}} \times 100. 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]. 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. 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. Age group-wise gender classifications are presented in Table5. ridges in the immediate pattern.
