Secondary Classification of Fingerprints With Small Letter Grouping with practical examples. If there is whorl pattern found on the thumb then ridge tracing will be done. Therefore, fair chances of occurrence of fingerprint in all types of crime. Comparison of average fingertip size in male and female fingerprints. The back-propagation neural network classifier was used to classify the gender [13] and the classification rate achieved was 92.67%. Outline the steps in taking a ridge count from a fingerprint. In 1896, Sir Edward Richard Henry developed a fingerprint classification system that uses all fingerprints (hence, also called a 10-digit system). Primary Classification A numerical system of classifying a full set of prints based on the whorl pattern. The ridge count is calculated by counting the number of ridges intervening between the delta and core [19]. If there is a loop pattern then ridge counting will be done. As a novel method, the optimal score assignment (OSA) method is proposed to classify gender. However, only one value is used to classify it in the henry classification line. Ridge ending and ridge bifurcation are two frequently used minutiae in most fingerprint matching algorithms. On each fingertip, the number of primary dermal ridges (the "ridge count") provides a measure of fingertip growth activity during the early fetal period (18, 20). Fingertip size is measured as another parameter to find gender. Ridge count of at Types of fingerprint patterns.ppt - Types of fingerprint. In addition to publishing its own journals, the division also provides traditional and digital publishing services to many client scholarly societies and associations. A maximum score of 10 is assigned for this FTS. 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.
