In 1897 , sir Edward Henry proposed a classification to arrange the various fingerprint patterns into a group known as henry classification, converted the ridge patterns of all ten fingerprints into letters and alphabets which can be arranged in the form of fractions. ridge count is obtained by making an imaginary line between the delta and the core and then counting the number of ridges that intersect the line. An optimal score is calculated for male and female from the internally collected fingerprint database. Frequency domain analysis of fingerprint [11] for the identification of gender produces a good classification rate. The low point on a ridge is called a col or saddle. f Major Division - is placed just to the left of the primary in the classification formula. This is the highest occurrence in comparison with other RC counts. No two individual posses same ridge characteristics.

Outline the steps in taking a ridge count from a fingerprint. placed immediately to the left of the primary classification column. A white space must always intervene between the delta and the first ridge to be counted. Values: Ridge tracing and Ridge counting. But, before jumping directly to the six divisions of Henrys fingerprint classification system modified by the FBI, lets take a look at the original Henrys classification system of fingerprints with a simple calculator.Table of ContentsHenry Classification Calculator For FingerprintOriginal Henry Classification SystemList of Fingerprint Classification System Originated From HenryFilling a Henry 10-digit Fingerprint CardHenry Fingerprint Classification System Modified by FBIOverview of the Henry Classification System (FBI Modified)#1 Primary Classification#2 Secondary Classification#3 SubSecondary Classification#4 Major Division Classification#5 Final Classification#6 Key Classification SystemExtension to Henry Classification By FBIShort Summary of Henry Fingerprint Classification System. As the scores assigned for a particular value of RC/FTS are different for male and female, the sum of these scores computed for each gender is distinguishable and thus declares more accurate results. These three patterns helps to classify the prints in all ten fingerprint classification. Ridges are common between two hilltops, such as between Kanturk and Scarr. Article (Note 4): Sub Secondary Classification of Fingerprint-> Rules-> Calculation Formula-> WorksheetCheck Now: Sub Secondary of Fingerprint With Practical Examples. Friction ridges or papillary ridges Elevated strips of skin that begin as raised apertures around the pores and then are joined together into rows forming the ridges. These frictions are provided during the birth to provide firm grasping and resistance to slipping. 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. The average RC values of male and female (for all fingerprints of the database) are compared in the line chart shown in Fig. The fingerprint patterns and ridge counts were evaluated using a computer based Hp Scanjet scanner and AutoCAD computer software. This method of gender identification will be helpful in short listing the suspects and victims from crime scenes and improves the performance of a system which is used for person recognition and human computer interfaces. As the fingerprint becomes the main part of policing and forensic science works. In Henrys fingerprint classification system, there are 6 main divisions with 3 common extensions. It is a special extension majorly used to classify the large groups of whorls patterns such as 32/32. In case of double loop, the ascending core is taken as constant for ridge counting and descending core will not be considered. FTS is computed using the scanner information. What are the tracing rules for Ridge tracing? A similar calculation is made assuming that the given image is female. Ridge count of the Loop and Ridge Tracing of the Whorl from Index, Middle and Ring Fingers.
