This paper proposes a novel computer vision approach that processes video sequences of people walking and then recognises those people by their gait. Human motion carries different information that can be analysed in various ways. The skeleton carries motion information about human joints, and the silhouette carries information about boundary motion of the human body. Moreover, binary and gray-level images contain different information about human movements. This work proposes to recover these different kinds of information to interpret the global motion of the human body based on four different segmented image models, using a fusion model to improve classification. Our proposed method considers the set of the segmented frames of each individual as a distinct class and each frame as an object of this class. The methodology applies background extraction using the Gaussian Mixture Model (GMM), a scale reduction based on the Wavelet Transform (WT) and feature extraction by Principal Component Analysis (PCA). We propose four new schemas for motion information capture: the Silhouette-Gray-Wavelet model (SGW) captures motion based on grey level variations; the Silhouette-Binary-Wavelet model (SBW) captures motion based on binary information; the Silhouette-Edge-Binary model (SEW) captures motion based on edge information and the Silhouette Skeleton Wavelet model (SSW) captures motion based on skeleton movement. The classification rates obtained separately from these four different models are then merged using a new proposed fusion technique. The results suggest excellent performance in terms of recognising people by their gait.; FAPESP Sao Paulo State Foundation

Early American crania show a different morphological pattern from the one shared by late Native Americans. Although the origin of the diachronic morphological diversity seen on the continents is still debated, the distinct morphology of early Americans is well documented and widely dispersed. This morphology has been described extensively for South America, where larger samples are available. Here we test the hypotheses that the morphology of Early Americans results from retention of the morphological pattern of Late Pleistocene modern humans and that the occupation of the New World precedes the morphological differentiation that gave rise to recent Eurasian and American morphology. We compare Early American samples with European Upper Paleolithic skulls, the East Asian Zhoukoudian Upper Cave specimens and a series of 20 modern human reference crania. Canonical Analysis and Minimum Spanning Tree were used to assess the morphological affinities among the series, while Mantel and Dow-Cheverud tests based on Mahalanobis Squared Distances were used to test different evolutionary scenarios. Our results show strong morphological affinities among the early series irrespective of geographical origin, which together with the matrix analyses results favor the scenario of a late morphological differentiation of modern humans. We conclude that the geographic differentiation of modern human morphology is a late phenomenon that occurred after the initial settlement of the Americas. Am J Phys Anthropol 144:442-453...

During an excavation in the 1970s, a disarticulated female human skeleton, later nicknamed Luzia, was discovered at 12m depth at Lapa Vermelha rockshelter in central Brazil. Radiocarbon dating of associated charcoal suggested an age of 11.4-16.4 ka for the skeleton. The scattering of the skeletal parts, some uncertainty about the exact provenience of the skeleton, and evidence of pervasive insect turbation in the archaeological layers have raised doubts about the accuracy of the age. Luminescence dates for the depositional ages of the sediments at Lapa Vermelha are reported here. Single-grain optically stimulated luminescence (OSL) of quartz along with grain-size, chemical and micro-morphological analyses of the sediments were employed to assess stratigraphic integrity, particularly the degree of sediment mixing. These various lines of evidence point to high stratigraphic integrity with little mixing at Lapa Vermelha. Sediments closest to where Luzia was recovered give OSL ages ranging from 12.7 to 16.0 ka, thus not refuting the original dates. (C) 2010 Wiley Periodicals, Inc.

Os recursos empregados para identificação humana variam desde antropologia física até o estudo dos ácidos nucléicos. Exemplos recentes como o Tsunami, na Tailândia e o Katrina, em Nova Orleans reforçam a necessidade de domínio de técnicas de extração do DNA no processo de identificação de corpos esqueletizados ou em estado de decomposição avançado que estiveram sob influência de ambiente aquoso. Neste sentido, o objetivo deste trabalho foi conhecer a casuística de situações que envolvam casos de afogamento, através dos registros do Instituto Médico-Legal Nina Rodrigues na cidade de Salvador - Bahia, além de, verificar o potencial de recuperação do DNA obtido de dentes humanos, imersos na água doce e salgada, por 1 mês. Foram utilizados 40 dentes sendo o DNA extraído pelo método orgânico e amplificado por PCR utilizando a amelogenina como iniciador. A eletroforese ocorreu inicialmente em gel de agarose e posteriormente em gel de poliacrilamida. Em seguida, foram selecionadas 10 amostras para amplificação através do sistema Powerplex® 16 System, sendo a eletroforese realizada em seqüenciador automático. No levantamento, observou-se 346 óbitos por afogamento, a maioria destes na água salgada (51...

Many methods based on biometrics such as fingerprint, face, iris, and retina have been proposed for person identification. However, for deceased individuals, such biometric measurements are not available. In such cases, parts of the human skeleton can be used for identification, such as dental records, thorax, vertebrae, shoulder, and frontal sinus. It has been established in prior investigations that the radiographic pattern of frontal sinus is highly variable and unique for every individual. This has stimulated the proposition of measurements of the frontal sinus pattern, obtained from x-ray films, for skeletal identification. This paper presents a frontal sinus recognition method for human identification based on Image Foresting Transform and shape context. Experimental results (ERR = 5,82%) have shown the effectiveness of the proposed method.

Pós-graduação em Ciência da Computação - IBILCE; Diversos métodos biométricos baseados em características físicas do corpo humano como impressão digital, face, íris e retina têm sido propostos para identificação humana. No entanto, para a identificação post-mortem, tais características biométricas podem não estar disponíveis. Nestes casos, partes do esqueleto do corpo humano podem ser utilizadas para identificação, tais como dentes, tórax, vértebras, ombros e os sinus frontais. Investigações anteriores mostraram, por meio de técnicas manuais para extração de características, que os padrões dos sinus frontais são altamente variáveis entre indivíduos distintos e únicos para cada indivíduo. Esta dissertação de mestrado tem por objetivo propor um método computacional para o reconhecimento de sinus frontais para identificação humana post-mortem em aplicações forenses. Para tanto, foram avaliados métodos de segmentação de imagens de radiografias anteroposteriores de sinus frontais. O método baseado na Transformada Imagem-Floresta demonstrou ser eficiente para segmentação dos sinus frontais das imagens de radiografias, exigindo mínima intervenção humana. Foram também investigadas e implementadas técnicas para extração de descritores geométricos e descritores baseados nas formas dos sinus frontais. Experimentos realizados em um banco de imagens contendo 90 radiografias anteroposteriores de 29 indivíduos mostraram que a técnica de extração de características baseada nos descritores de contexto da forma foi a mais eficaz...

During an excavation of a site of the corded ware culture in the Saale-Unstrut-Valley (ca. 3000 BC) in Germany, a soil sample from the pelvis of a human skeleton was studied under palaeoparasitological aspects. Eggs of the trematode Fasciola hepatica and of the nematode genus Capillaria were found. This is the first case of a direct association of a F. hepatica-infestation to both a prehistoric human skeleton and domesticated animal remains. Sheep and cattle bones were present at the same site and F. hepatica eggs were found in bovine samples. This strongly points toward an existing infection cycle, involving humans as a final host.

The discovery of an early Upper Paleolithic human burial at the Abrigo do Lagar Velho, Portugal, has provided evidence of early modern humans from southern Iberia. The remains, the largely complete skeleton of a ≈4-year-old child buried with pierced shell and red ochre, is dated to ca. 24,500 years B.P. The cranium, mandible, dentition, and postcrania present a mosaic of European early modern human and Neandertal features. The temporal bone has an intermediate-sized juxtamastoid eminence. The mandibular mentum osseum and the dental size and proportions, supported by mandibular ramal features, radial tuberosity orientation, and diaphyseal curvature, as well as the pubic proportions align the skeleton with early modern humans. Body proportions, reflected in femorotibial lengths and diaphyseal robusticity plus tibial condylar displacement, as well as mandibular symphyseal retreat and thoracohumeral muscle insertions, align the skeleton with the Neandertals. This morphological mosaic indicates admixture between regional Neandertals and early modern humans dispersing into southern Iberia. It establishes the complexities of the Late Pleistocene emergence of modern humans and refutes strict replacement models of modern human origins.

Although disorders of the skeleton are individually rare, they are of clinical relevance because of their overall frequency. Many attempts have been made in the past to identify disease groups in order to facilitate diagnosis and to draw conclusions about possible underlying pathomechanisms. Traditionally, skeletal disorders have been subdivided into dysostoses, defined as malformations of individual bones or groups of bones, and osteochondrodysplasias, defined as developmental disorders of chondro-osseous tissue. In light of the recent advances in molecular genetics, however, many phenotypically similar skeletal diseases comprising the classical categories turned out not to be based on defects in common genes or physiological pathways. In this article, we present a classification based on a combination of molecular pathology and embryology, taking into account the importance of development for the understanding of bone diseases.

Most of the signaling effectors located downstream of receptor activator of NF-κB (RANK) activation are calcium-sensitive. However, the early signaling events that lead to the mobilization of intracellular calcium in human osteoclasts are still poorly understood. The Ca2+-sensitive fluorescent probe Fura2 was used to detect changes in the intracellular concentration of Ca2+ ([Ca2+]i) in a model of human osteoclasts. Stimulating these cells with receptor activator of NF-κB ligand (RANKL) induced a rapid and significant increase in [Ca2+]i. Adding extracellular Ca2+ chelators, depleting intracellular stores, and the use of a phospholipase C inhibitor all indicated that the Ca2+ was of extracellular origin, suggesting the involvement of a Ca2+ channel. We showed that none of the classical Ca2+ channels (L-, T-, or R-type) were involved in the RANKL-induced Ca2+ spike. However, the effect of high doses of Gd3+ did suggest that TRP family channels were present in human osteoclasts. The TRPV-5 channel was expressed in osteoclasts and was mainly located in the cellular area in contact with the bone surface. Furthermore, the RNA inactivation of TRPV-5 channel completely inhibited the RANKL-induced increase in [Ca2+]i, which was accompanied in the long term by marked activation of bone resorption.

In the skeleton, male and female characteristics lie along a continuum of morphologic configurations and metric values. Size alone is not the best indicator of sex. In contrast, morphologic differences that arise from genetically sex-linked growth and development allow better separation of the sexes. This study presents a new morphologic indicator of sexual dimorphism in the human mandible. A sample of 300 mandibles from adults of known sex primarily from the Dart collection was analyzed. Of these, 100 were found to have obvious bony pathologies and/or excessive tooth loss ("pathologic" sample). Thus, the normative sample consisted of 200 individuals (116 males, 84 females). Examination of morphologic features led to the discovery of a distinct angulation of the posterior border of the mandibular ramus at the level of the occlusal surface of the molars in adult males. Flexure appears to be a male developmental trait because it is only manifest consistently after adolescence. In most females, the posterior border of the ramus retained the straight juvenile shape. If flexure was noted, it was found to occur either at a higher point near the neck of the condyle or lower in association with gonial prominence or eversion. In the normative sample...

In der vorliegenden Arbeit wurde ein dreidimensionales Computermodell erstellt, mit welchem die Berechnung der Druckverteilung auf den menschlichen Hüftgelenkflächen unter synthetisch generierter Bewegung mittels realitätsnah modellierter Muskel möglich ist. Damit wurde die Druckverteilung für den geregelten Zweibeinstandes berechnet. Da dafür kein geeignetes Modell existierte, lag die Hauptaufgabe in der Erstellung eines komplexen, biomechanischen Menschmodells (Anthropion), das die geforderten Funktionalitäten umfasste. In der Vergangenheit wurden zwar viele biomechanische Modelle entwickelt, diese konzentrieren sich aber meistens auf die Beschreibung eines eng umrissenen Aspekts des biomechanischen Gesamtsystems und sind komplett unabhängig voneinander. Allgemeinere Modelle, die einen weiteren Bereich des biomechanischen Gesamtsystems abdecken, existieren kaum bzw. waren zur Bearbeitung der vorliegenden Fragestellung nicht geeignet. Daher erfolgte im Zuge dieser Arbeit die Integration mehrerer dieser speziellen Modelle zu dem komplexen, biomechanischen Muskel-Skelett-Menschmodell Anthropion mit Bewegungskontrolle und realitätsnah arbeitenden Muskeln. Die Basis dieses als Computersimulation realisierten Modells ist ein dreidimensionales Mehr-Körper-System-Modell des Menschen mit Segmenten...

ABSTRACT Bone research is limited by available methods to detect changes in bone metabolism. While dual x-ray absorptiometry is rather insensitive, biochemical markers are subject to significant intra-individual variation. Within the presented study, we evaluated isotopic labeling of bone using 41Ca, a long living radiotracer, as an alternative approach. After successful labeling of the skeleton, changes in the systematics of urinary 41Ca excretion are expected to directly reflect changes in bone Ca metabolism. A minute amount of 41Ca (100 nCi) was administered orally to 22 postmenopausal women. Kinetics of tracer excretion were assessed by monitoring changes in urinary 41Ca/40Ca isotope ratios up to 700 days post dosing using accelerator mass spectrometry and resonance ionization mass spectrometry. Isotopic labeling of the skeleton was evaluated by two different approaches: a) urinary 41Ca data were fitted for each individual to an established function consisting of an exponential- and a power law term; b) 41Ca data were analyzed by population pharmacokinetic (NONMEM) analysis to identify a compartmental model for describing urinary 41Ca tracer kinetics. A linear three compartment model with a central compartment and two sequential peripheral compartments was found to best fit the 41Ca data. Fits based on the use of the combined exponential/power-law for describing urinary tracer excretion showed substantially higher deviations between predicted and measured values than fits based on the compartmental modeling approach. By establishing the urinary 41Ca excretion pattern using data points up to day 500 and extrapolation of these curves up to day 700...

Although the concept of race has been thoroughly criticised in biological anthropology, forensic anthropology still uses a number of methods to determine the ‘race’ of a skeleton. The methods must be evaluated to see how effective they are given large individual variation. This study used 20 cases of skeletons of varied provenance to test whether the nine published methods of ‘race’ determination, using a range of various approaches, were able to consistently identify the ethnic origin. No one individual was identified as belonging to just one ‘major racial class’, e.g. European, meaning that complete consistency across all nine methods was not observed. In 14 cases (70%), various methods identified the same individual as belonging to all three racial classes. This suggests that the existing methods for the determination of ‘race’ are compromised. The very concept of ‘race’ is inapplicable to variation that occurs between populations only in small ways and the methods are limited by the geographic population from which their discriminant functions or observations of morphological traits were derived. Methods of multivariate linear discriminant analysis, e.g. CRANID, are supposed to allocate an individual skull to a specific population rather than a ‘major race’. In our analysis CRANID did not produce convincing allocations of individual skeletons to specific populations. The findings of this study show that great caution must be taken when attempting to ascertain the ‘race’ of a skeleton...

The TP1 skeleton discovered in 1929 during quarry work at Tuinplaas, near Pretoria, South Africa, has generally been considered to date from the Middle Stone Age on the basis of artefacts and biostratigraphy at the site. However, no direct association between the skeleton and the lithics or faunal remains could be demonstrated, and the date of TP1 has remained uncertain. We present U-series dates measured directly on a fragment of TP1 using laser ablation mass spectrometry. The results constrain the age to between 11.0 ± 0.7 and 20 ± 3 kyr, placing TP1 in the Late Stone Age.

While 'surgical' practices such as trepanations are well attested since the first stages of the European Neolithic, the amputation of limbs in Prehistoric periods has not been well-documented until the case presented here. The particularly well-preserved remains of an aged male were recently uncovered in the Neolithic site (4900-4700 BC) of Buthiers-Boulancourt in the vicinity of Paris, France. It was already noticed in situ that the distal part of the left humerus was abnormal and this led us to the hypothesis of a partially healed 'surgical' amputation.The further investigations reported here confirm a traumatic origin and a partial cicatrisation after surgery, indicating that the patient survived. It also proves the remarkable medical skills developed during Prehistorical times. In addition, the associated grave goods are original, including the skeleton of an animal, a polished schist axe and a massive 30 cm long flint pick. Despite the serious handicap from which he suffered in this pastoral-agricultural community, the buried man obviously enjoyed some particular social status, as suggested by the remarkable and 'prestigious' accompanying grave-goods. If indeed this man benefited from some form of community care...

Many methods based on biometrics such as fingerprint, face, iris, and retina have been proposed for person identification. However, for deceased individuals, such biometric measurements are not available. In such cases, parts of the human skeleton can be used for identification, such as dental records, thorax, vertebrae, shoulder, and frontal sinus. It has been established in prior investigations that the radiographic pattern of frontal sinus is highly variable and unique for every individual. This has stimulated the proposition of measurements of the frontal sinus pattern, obtained from x-ray films, for skeletal identification. This paper presents a frontal sinus recognition method for human identification based on Image Foresting Transform and shape context. Experimental results (ERR = 5,82%) have shown the effectiveness of the proposed method.
