ISABELA STATE UNIVERSITY Cauayan Campus A Review Material on Personal . 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. chemistry. The ridges make a backward turn in loops but they do not twist. Comparing local structures by correlation or tree-matching. Following is the example of a Henry fingerprint Classification system modified by FBI extension, based on the above example. . This method of gender identification will be helpful in short listing the suspects and victims from crime scenes and improves the performance of a system which is used for person recognition and human computer interfaces. The program yields semi-automated ridge counts and logs the location of the user-selected core and delta points to aid in the training of new researchers and ensure the repeatability of count.

You should check our dedicated article on how to fill 10-digit fingerprint cards with rules. In the Henry key classification system, you have to count the first loop that is appearing on the card except for loops on the little finger. In Image #3 at the right, there is a line drawn between the delta and core. The major classification is taking from the thumb of the hand. 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. *Whorls will have a right ridge count & a left ridge count. From Table1, it is identified that the minimum as well as the maximum RC are greater for male than female. (1). These ridges are also present on the toes, the palms of the hands, and the soles of the feet. ridge count is obtained by making an imaginary line between the delta and the core and then counting the number of ridges that intersect the line. Also, all these values differ for male and female in all the age groups. (7). Slider with three articles shown per slide.
