A person's fingerprints are based on the patterns of skin ridges (called dermatoglyphs) on the pads of the fingers. This roughened skin makes it easier to grip things and, up close, it appears as patterns of tiny ridges and furrows. *Numerical values are assigned to each finger *If the finger has a whorl pattern, then plug that number into the primary classification equation. In a fingerprint card, there is a specific layout and position of each finger of the hand. 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. Loop patterns account for 60-65 . editors. From Table2, it is clarified that the ridge count of 31 was found to be 287 times among the 4100 female fingerprints.
