Measured fingerprint RCs are listed in an ascending order and the number of each RC is counted. If there is whorl pattern found on the thumb then ridge tracing will be done. When multicollinearity occurs, least squares estimates are unbiased, but their variances are large so they may be far from the true value. Scores for the remaining FTS are determined by Eq. Activity 3. In this classification, the little fingers of both hands are employed, and ridge counting is performed on loops and whorls patterns. Tap here to review the details. In secondary classification, the pattern type of the index fingers is designated by a capital letter. where RCF and FTSF are the respective scores of ridge count and fingertip size assigned for female fingerprints. With respect to core and delta, RCs are determined (traditional method) and in addition, ridge counts measured diagonally (at 45 and 135) with respect to the core points are averaged. Using the ridge thickness to valley thickness ratio (RTVTR) and white lines count features [4], gender was classified.
