In case of whorl pattern, the ridge counting is performed in the manner for right little finger, the ridge counting is done from left delta to core of the pattern and for the left little finger, the ridge counting is done from right delta to the core . A white space must always intervene between the delta and the first ridge to be counted. Fingerprints are unique patterns, made by friction ridges (raised) and furrows (recessed), which appear on the pads of the fingers and thumbs. $$, $$ {\text{RC score }} = \, \frac{{{\text{Occurrence \% of a particular RC}}}}{{{\text{Maximum occurence \% }}}} \times 100. Clipping is a handy way to collect important slides you want to go back to later. Information on the gender of a person plays a vital role in crime investigation, authentication and statistical report on the visitors. Ridges are common between two hilltops, such as between Kanturk and Scarr. The FTS values of male and female are compared in the line chart in Fig. This is the highest occurrence in comparison with other RC counts. Measured fingerprint RCs are listed in an ascending order and the number of each RC is counted. Key Classification: 1st loop count on the card excluding little finger.

Also, the OSA method works well even for the poor quality fingerprints. Fingerprint is an impression made by the friction ridges that are almost parallel at constant crest to crest wavelength. Instant access to millions of ebooks, audiobooks, magazines, podcasts and more. A detailed analysis of RC and FTS was carried out in the previous section. 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. For example, as in Table2, RC of 25 has its occurrence percentage as 3.2195. Fingertip size is measured as another parameter to find gender. The individuality is not based number, but also have the relative locations to one another in the prints. The fingerprints were categorized into four age groups, viz., 812, 1318, 1825 and above 25.
