Gender classification from fingerprints is an important step in forensic anthropology in order to identify the gender of a criminal and minimize the list of suspects search. A dataset of 10-fingerprint images for 2200 persons of different ages and gender (1100 males and 1100 females) was analyzed. Features extracted were; ridge count, ridge thickness to valley thickness ratio (RTVTR), white lin...

Abstract Background The present study is an attempt to explore the distribution of different minutiae in two topological areas thumbprint and its application determine sex distinctions. Methods For this purpose, a sample 100 subjects (50 males 50 females) ranging age from 18 years 25 were taken Shimla (North India). A modified standardized method was adopted count classify 20 types minutiae. Re...

Background: In forensic sciences, the nature and variability of configurations of epidermal ridge minutiae has practically been explored in the evaluation and comparison of fingerprints, including partial fingerprints. The objectives of the present study were to determine the potential of fingerprint minutiae (level two features) in estimation of sex using likelihood ratio and posterior probabi...

Several previous studies have investigated the gender difference of the fingerprint features. However, regarding to the statistical significance of such differences, inconsistent results have been obtained. To resolve this problem and to develop a method for gender determination, this work proposes and tests three fingertip features for gender determination. Fingerprints were obtained from 115 ...

UNLABELLED The human palms and soles are textured with skin different to that of the other body surface. Instead of sebaceous glands or hairs, there are sweat glands opening into epidermal ridges. They are variously oriented, thus forming different patterns. The aim of the study was to assess some dermatoglyphic patterns, the TRC and the a-b ridge count in a sample of patients and a control gro...

Introduction: The existing bone is regarded as an important criteria in dental implants. In this regard, the radiographic modality is of great significance in quantifying the remaining bone, and CBCT accurately represents height and width of the existing bone. Therefore, this study aimed to evaluate the frequency distribution of the edentulous posterior mandibular ridge types using cone beam co...

Computing a reliable orientation map is a critical step in automatic fingerprint analysis and especially for analysis of fingermarks obtained at crime-scenes especially. Being the initial step of processing image information it may influence the further operations: registration, enhancement and matching. We suggest a new way of automatic frequency estimation improving the state-of-theart result...

The present study has attempted to explore the relationship among three Slovakian Haban populations with other Central European populations using finger ridge-count data. A multivariate approach to the analysis of finger-ridge count data allows for the study of population relationships using R-matrix calculations. Historical and ethnographic evidence suggests that the Haban populations have rem...
