From Table2, it is clarified that the ridge count of 31 was found to be 287 times among the 4100 female fingerprints. A ridge count between any two points on the fingerprint is defined as the number of ridges running between the two points on the fingerprint. Looks like youve clipped this slide to already. The process of manual fingerprint classification always starts with primary classification. In the proposed method, instead of considering counting only between the core and delta, an effort is taken to count the ridges of the entire fingertip. In the sub-secondary classification system. In doing so, you just have to place it in the numerator, and place immediately left of the major division value. No two individual posses same ridge characteristics. Complex Intell.

The singular point area is defined as a region where the ridge curvature is higher than normal and where the direction of the ridge changes rapidly [15]. The low point on a ridge is called a col or saddle. Ridge Feature Recognition; Ridge Counting; Charted Enlargement (Loop) Charted Enlargement (Whorl) Charted Enlargement (Arch) IMPORTANT! These frictions are provided during the birth to provide firm grasping and resistance to slipping. cross the line of count drawn between the delta Copy. The maximum success rate attained is 88.41% for the age group 1825years and a good success rate of 90.11% is achieved for the right hand ring finger. Now, using Eq.

This method produced a success rate of 88.41% and 90.11% is achieved for the right hand ring finger. For ridge counting, draw an imaginary line from core to delta, and count the intervening ridges between them. Fingertip size is measured as another parameter to find gender. Values vary from 1/1 to 32/32.2. For loop pattern, ridge counting is done in following manner. thus these are the principles of fingerprint help us to give the presence of someone at the crime scene and various technology to identify, visualize and verification of the fingerprint.
