“…Classification rates from this study (89% for males, 86% for females, 88.2% overall) are not as high as other validation studies using pubic bone morphology , but are similar to the rates found by McBride et al and Ubelaker and Volk . While the classification rates reported here may be slightly less than those found in other discriminant function studies , this study demonstrates a high probability of correctly predicting sex to allow for the identification of an individual. In addition, these measurements performed better than the individual traits assessed on fragmentary remains at 60–80% accuracy by Bruzek .…”

“…The landmarks of the pelvis are often difficult to assess due to the morphological irregularity of the elements considered. For example, in previous metric studies of pubic bone length, acetabular endpoint evaluation was inconsistently defined and pubic body width has been described as both the width at the pubic symphysis midpoint and the shortest distance from the face to the obturator foramen . This study found that these were two different measurements on most individuals and that the pubic symphysis midface to obturator measurement was not as reliable as the minimum pubic body width.…”

“…Few studies, however, have metrically assessed the pubic body and elements surrounding it for sexual differences as most studies focus on pubic bone length . While morphological studies have high accuracy levels, metric measurements are reliable, are less impacted by observer experience, and may provide a means to quantify the variation captured in these nonmetric studies . Analyses using metric assessment of at least one pelvic feature range in accuracy of sex estimation from 69 to 99% ().…”

“…High sex estimation accuracies have been reported using measurements of the pubic bone, indicating that this bone shows promise for future research (). Notably, the aforementioned metric methods do not include measurements of the pubic body, as the measurement of the pubic bone is limited to overall length.…”

Biological sex estimation of skeletal remains is essential in forensic and archaeological analyses. Anthropologists most often use the pelvis, which is the most sexually dimorphic element both morphologically and metrically. While nonmetric pubic bone features have been studied extensively, few metric studies have examined this individual bone for dimorphism. For this study, three observers examined three previously identified and ten novel measurements of the pubic body on a modern sample of isolated pubic bones from the Maricopa County Forensic Science Center (FSC), in Phoenix, Arizona (n = 400). A relationship between pubic body measurements and biological sex was demonstrated, with significant correlations. Discriminant function analyses found that five measurements, four of which were novel, discriminated between males (89%) and females (86%). Observer experience level did not significantly impact the results. These five measurements were reliable and show promise for inclusion in metric methods for assessment of sex.

Recent research has explored the possibility of extracting ancillary information from primary biometric traits, viz., face, fingerprints, hand geometry and iris. This ancillary information includes personal attributes such as gender, age, ethnicity, hair color, height, weight, etc. Such attributes are known as soft biometrics and have applications in surveillance and indexing biometric databases. These attributes can be used in a fusion framework to improve the matching accuracy of a primary biometric system (e.g., fusing face with gender information), or can be used to generate qualitative descriptions of an individual (e.g., "young Asian female with dark eyes and brown hair"). The latter is particularly useful in bridging the semantic gap between human and machine descriptions of biometric data. In this paper, we provide an overview of soft biometrics and discuss some of the techniques that have been proposed to extract them from image and video data. We also introduce a taxonomy for organizing and classifying soft biometric attributes, and enumerate the strengths and limitations of these attributes in the context of an operational biometric system. Finally, we discuss open research problems in this field. This survey is intended for researchers and practitioners in the field of biometrics.
