A core point is the turning point of an innermost ridge. [4], and the proposed method (age group of 1925). Required fields are marked *. In this the pattern on it is represented by capital letter, the right index in the numerator and left index in the denominator. For this study, the RTVTR, and white lines count features were analyzed for 255 persons (150 males, and 105 females). 6 What are the tracing rules for Ridge tracing? Thus, FTS scores are computed individually for male (4030 samples) and female (4100 samples) of all the internal databases and shown in Table4. The SlideShare family just got bigger. o Fragments and dots are counted as ridges only if they appear as thick as the surrounding ridges. According to them, the females fingerprint is characterized by a high RTVTR, while the males fingerprint is characterized by low RTVTR. It is characterized by almost parallel ridges that form distinguishable configurations. From the analysis, it is observed that the ridge count and the fingertip size of the fingerprints are more for male than female. To distinguish . Based on the ridge count of the left thumbprint, the right thumb designation can be determined based on the conversion chart. It appears that you have an ad-blocker running. Ridge patterns exhibit many properties that reflect the biology of individuals.

In the fingerprint card, the major divisions ridge count or ridge trace values are placed immediately to the left of the primary classification column. The ridge features extracted are ridge count, ridge length, ridge curvature direction (concav e shape and conve x shape), and ridge type between two minutiae. The back-propagation neural network classifier was used to classify the gender [13] and the classification rate achieved was 92.67%. Finger ridge count (an index of the size of the fingerprint pattern) has been used as a model trait for the study of human quantitative genetics for over 80 years. Minutia points are classified by: Type Orientation Spatial frequency Curvature Position Let's examine the macro features, then the micro features of a fingerprint. 1 Clear inspection reveals dozens of other imperfections such as ridge endings, ridge bifurcations, island ridges etc. These are called level 1 details. Thus, the proposed method achieves better results than all the methods discussed. Values vary from 1/1 to 32/32.2. Variations in ridge parameters for male and female are found statistically [1, 2].
