Automatic facial age estimation
The reliability of automatically estimating human ages, by processing input facial images, has generally been found to be poor. On other hand, various real world applications, often relating to safety and security, depend on an accurate estimate of a person’s age. In such situations, Face Image …

Age Estimation of Fetal Skeletal Remains from the Forensic Context
… from historic (1902-1917) fetal remains of known age. The second consisted of measurements from modern fetal remains of known age from the forensic context. Using these samples in the different prediction models for aging fetal remains, the accuracy of each was determined.

Age estimation in the living: a test of 6 radiographic methods
… that there is a requirement for methods of age estimation of the living to be rigorously tested to ensure that they are accurate, reliable and valid for use in forensic and humanitarian age estimation. The necessity for accurate and reliable methods of age estimation are driven both by …

Histological age estimation of the midshaft clavicle using a new digital technique.
Histological methods to estimate skeletal age at death, in forensic cases, are an alternative to the more traditional gross morphological methods. Most histological methods utilize counts of bone type within a given field for their estimation. The method presented in this paper uses the percentage …

Examining external morphological characteristics of Lucilia sericata pupae for age estimation in medico-legal investigations
… known as the post-mortem interval (PMI). The age of the oldest insects can provide the most precise estimation of the PMI. Flies undergo different stages of development. All the immature stages can be utilized as evidence at death scenes. Out of all the immature stages, pupae represent the …

Incorporating the Weathering Hypothesis and Virtual Imaging to Multivariable Macroscopic Adult Age Estimation for Forensic Anthropology
Adult age estimation in forensic anthropology is critical to the identification of unknown individuals across medico-legal, political violence, and humanitarian contexts. Despite decades of methodological development, current approaches remain accurate but imprecise—yielding wide age intervals that …

An Exploration of Histological Variation in the Human Rib: Applications for Age Estimation Methods in Applied Anthropology
… that address issues related to histological age-at-death estimation of the human rib. The overarching sample for the dissertation consists of N=246 individuals from three North American locations ranging in age from 16-102 years (M=55, SD=20.23). The locations include the Texas State …

Bone age estimation using machine learning approach: An assessment using hand and wrist bones of South African children
… and whether that individual is a minor. Bone Age Assessment (BAA) achieves this, as it is a clinical process used to establish an individual's biological profile. A large proportion of the South African population resides in rural areas where the fully functional civil registration system is …

Forensic Discrimination, Age Estimation, and Spectral Optimization For Trace Detection of Blood On Textile Substrates Using Infrared Spectroscopy and Chemometrics
… chemical-based tests that have disadvantages (i.e., toxicity and sensitivity to light). The feasibility of remote spectroscopic detection to visualize blood on forensically relevant textiles was evaluated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). …

Age estimation using epiphyseal closure at the wrist joint : an investigation of individuals of African origin, age 14 to 22 years
Age estimation techniques allow the researcher to compare chronological age, calculated from the individual's date of birth, to the level of functional and skeletal development known as biological age. This is useful in forensic cases where the age of an individual whether living or post mortem is …

Assessing the applicability of the Greulich and Pyle (1959) skeletal age estimation method to South African children between 0 and 13 years
The assessment of skeletal age (SA) in both clinical and forensic settings serves to estimate the degree of development and biological maturation of a child. This is a suitable and frequently used technique, as skeletal age is a valuable indicator which can be analysed from birth until the …

Study of Pelvic Growth and Development Through Examination of Interlandmark Distances and Geometric Morphometric Analyses: Implications for Subadult Skeletal Sex and Age Estimation
… relied upon by forensic anthropologists for age and sex estimations of unidentified skeletal remains. However, because subadult individuals are an underrepresented demographic in skeletal collections there is a lack of ontogenetic knowledge of the sub-elements (ilium, ischium, and pubis) and …

A comparison of the accuracy of various methods of postnatal gestational age estimation; including Ballard score, foot length, vascularity of the anterior lens, last menstrual period and also a clinician's non-structured assessment
Rationale Gestational age is a strong determinant of neonatal mortality and morbidity. Early obstetric ultrasound is the clinical reference standard, but is not widely available in many developing countries. There is a well recognised need to identify reliable and simple methods of postnatal …

In Support of a Rationally Managed Fishery: Age and Growth in Patagonian Toothfish (<i>Dissostichus eleginoides</i>)
… Stock structure, critical to good fisheries management, can be inferred from growth differences between areas, but available growth data are compromised by inconsistencies in age estimation methods, sampling and sample sizes, and techniques used to derive estimates. I asked the scientific …

A comparative microscopic study of human and non-human long bone histology.
… nonhuman bone were insufficient. Additionally, age estimation in bone may help in the identification of human individual, which can be done by using a histomorphometric method. Age estimation is based on bone remodeling process, where microstructural parameters have strong correlations with age. …

The Aging of Two Madtom Catfish Species From a Southwest Missouri Stream
Accurate techniques for age estimation of fishes are essential for determining the effects of resource management and to answer other life-history questions. Validation of an age estimation technique is important to insure that age is not over-or under-estimated. In this study two species of madtom …
