Ridge Counting in Fingerprints: Rules, Need, Calculation With Images

Ridge Counting in Fingerprints Rules, Need Calculation With Images

Ridge counting is a technique that involves counting the intervening ridges present between the core and delta of a fingerprint. In essence, this method quantifies the ridges between these two reference points, helping to categorize fingerprints based on their ridge counts. Ridge counting is mostly used for loop patterns. For arches, ridge counting is generally
