Finger ridge count (an index of the size of the fingerprint pattern) has been used as a model trait for the study of human quantitative genetics for over 80 years. These three patterns helps to classify the prints in all ten fingerprint classification. Most of the early work was based on general-purpose image processing techniques Gender classification from fingerprint ridge count and fingertip size using optimal score assignment, $$ {\text{RC}} = a + \frac{1}{2}\left( {b + c} \right).
