Fingerprint Factoid: 60% of people have loops, 35% have whorls, and 5% have arches * Characteristics of Fingerprints Forensic examiners look for Core (the center of a whorl or loop) Deltas (triangular regions near a loop) Ridge count Counting from the core to the edge of the delta Distinguishes one fingerprint from another * Characteristics of . editors. The average RC values of male and female (for all fingerprints of the database) are compared in the line chart shown in Fig. In the same manner as inn major division classification. Loops A loop is that type of fingerprint pattern in which one or more of the ridges enter on either side of the impression, recurve, touch or pass an imaginary line drawn from the delta to the core, and terminate or tend to terminate on or toward the same side of the impression from whence such ridge or ridges entered. Copy. Approximately 255 of population have 1/1 value, it means all their fingers have arch or loop. 5. Ridge counts were determined for all 8130 fingerprints of 403 male and 410 female fingerprints and analyzed. Ferroprussinate was used as the developer. Your email address will not be published. The ridge counting of the whorls in the final classification is very rarely used. The acceptance of fingerprint evidence in the court of law based on assumption that no two individual posses the identical fingerprints. Given two points in the fingerprint image, the present ridge count process determines the length of the line (or bar) joining the points in terms of number of ridge distances, i.e., the number of times . Loop patterns account for 60-65 . Therefore, fair chances of occurrence of fingerprint in all types of crime.
