For the fingerprint image I for which gender is to be identified, scores are assigned for ridge count and fingertip assuming that the given image is male. However, only one value is used to classify it in the henry classification line. In case of double loop, the ascending core is taken as constant for ridge counting and descending core will not be considered. The section Conclusion concludes the proposed work and briefs the future work. WCDX is an acronym for Whorl, Central Pocket, Double, and Accidental loop whorls. UNIQUENESS: the fingerprint is unique. Designated by specific letter (I, M, O).4. Also, the OSA method works well even for the poor quality fingerprints. Ridge counts were determined for all 8130 fingerprints of 403 male and 410 female fingerprints and analyzed. In this classification, only whorls are classified and named down based on the pattern appearing on all of the fingers. In a fingerprint card, there is a specific layout and position of each finger of the hand. According to them, the females fingerprint is characterized by a high RTVTR, while the males fingerprint is characterized by low RTVTR. Best Answer. AGREEMENT: The ridge flow, characteristics and / or details appear in the same relative position with the same intervening ridge count, allowing for explainable differences, so to enable the practitioner to reach their conclusion.
