Detecção de movimentos não usuais no espaço_fase / Detection of unusual motion in space-phase

Hennemann, Luciano 22 February 2008 (has links)
Made available in DSpace on 2015-03-05T13:59:44Z (GMT). No. of bitstreams: 0 Previous issue date: 22 / Nenhuma / Este trabalho tem como finalidade apresentar um modelo para detecção de comportamentos não usuais baseados em trajetórias. O modelo segue uma linha de pesquisa bastante atual na área de câmeras inteligentes ou vigilância electrônica que tende a concorrer com a enorme variedade de dispositivos baseadas em hardware hoje disponíveis no mercado. O fundamento está no processamento das trajetórias de pedestres ou objetos adquiridas por meio de filmagens feitas de ambientes com tráfego. O modelo é fundamentado em um período de treinamento, onde irá aprender o perfil das trajetórias selecionando, agrupando e posteriormente, guardando-as em um banco de dados. Depois irá compará-las com trajetórias novas que vão sendo adquiridas continuamente no período de teste ou operação propriamentte dito. No período de teste, uma trajetória será classificada com usual se compatível com as trajetórias adquiridas durante o treinamento, ou não usual, caso contrário. Neste trabalho, portanto, serão apresentados algoritmos que detectam / This work aims to present a model for detection of unusual motion based on trajectories. This model relates to the research field on intelligent cameras and surveillance systems, that tends to compete nowadays with the enormous range of devices based in hardware available on the market. The main idea of the proposed approach is to analyze trajectories acquired from film scenes. The first step of the algorithm consists of a training period, that learns the profile of trajectories, selecting, grouping and later, keeping them in a database. After that, the algorithm compares new trajectories that are being acquired continously in the test period. In test period, one given trajectory will be classified as usual if it is compatible with the trajectories acquired during the training period, or unusual otherwise. This work, therefore, will present algorithms that detect patterns of similarity between a set of trajectories in the training period with each new trajectory acquired in the test period

Céramique, habitat et territoires au premier âge du Fer en Bourgogne orientale (du VIIIe au Ve siècle avant J.-C.) / Pottery, settlement and territories in the Early Iron Age in Eastern Burgundy (8th-5th century BC)

Labeaune, Régis 23 November 2016 (has links)
Jusque dans les années 1980, le premier âge du Fer en Bourgogne orientale était connu essentiellement par les fouilles des nécropoles tumulaires et des habitats de hauteur. Les travaux sur les habitats de plaine étaient très lacunaires et reposaient très largement sur des observations réalisées lors de découvertes fortuites. Depuis une vingtaine d’années, le développement de l’archéologie préventive lié aux différents travaux d’aménagement du territoire a permis d’effectuer de nombreux décapages de grande envergure. Grâce à ces chantiers, nos connaissances sur les habitats de plaine se sont développées et ont été réactualisées. Pour aborder ces sites le choix s’est fondé sur les plus caractéristiques soit en raison de leur surface ou soit en fonction du mobilier archéologique recueilli. Le corpus se compose de 110 habitats dont 98 ont été découverts lors d’opérations d’archéologie préventive. Comme beaucoup de ces sites ne sont pas publiés, les volumes 2 et 3 présentent la documentation des sites, les études et les planches de mobilier qui ont servi d’outils de référence à l’étude. Ce sont donc 250 ensembles clos découverts sur ces habitats de plaine du premier âge du Fer qui permettent de proposer une sériation du mobilier, associant céramique et métal, pour aboutir à une typologie précise de cette période pour la région. En complément, l’étude des structures présentes sur ces différents habitats propose une hiérarchisation des sites dont le nombre augmente fortement au premier âge du Fer et témoigne de la spécificité de ce territoire rural, principalement liée à une activité agro-pastorale. / Up until the 1980s the excavation of monumental cemeteries and hilltop settlements provided most of the information on the Early Iron Age in Eastern Burgundy. Studies of lowland settlements were few and far between and consisted mainly of observations from fortuitous discoveries. During the last 20 years the rise of development led archaeology carried out prior to various building developments has provided the opportunity of large scale excavations. These works have developed and renewed our knowledge of lowland settlements. This approach has focused on the most characteristic sites either because of their large surface area or because of their finds. The corpus includes 110 settlements, 98 of which were discovered through development led archaeology. As many of the sites remain unpublished, the volumes n° 2 and 3 present the site documentation, the specialised studies and the drawings of the objects that are the references for this study. The 250 assemblages discovered on the lowland settlements of the Early Iron Age form the basis of a seriation of the finds that associates pottery and metal to establish a precise typology for this period and for the area. Also, the study of the features themselves proposes a hierarchy of the settlements the number of which greatly increases during the Early Iron Age and bears witness to the specificity of this rural territory mainly linked to mixed farming.

Analyse spatiale à Saqqâra des origines à la fin de l'Ancien Empire : les exemples des complexes funéraires de Netjerikhet et de Sekhemkhet / Spatial analysis occupation at Saqqara from the origins to the end of the Ancient Kingdom : examples of the Funerary Complexes of Netjerikhet and Sekhemkhet

Noc, Eloïse 14 November 2015 (has links)
Cette étude est une analyse spatiale des vestiges archéologiques datant des origines à la fin de l'Ancien Empire des complexes funéraires de Netjerikhet et de Sekhemkhet à Saqqâra. L'objectif de ce travail est de comprendre l'occupation spatiale, l'enjeu étant de pouvoir traiter la quantité très importante d'informations issues des publications. Pour cerner l'ensemble de la documentation à examiner, une base de données et un système d'information géographique (SIG) ont été créés. Grâce à ces outils informatiques, tous les artefacts ont ainsi pu être enregistrés et une analyse des relations qu'entretiennent les différentes entités recensées a pu être menée pour tenter de comprendre comment s'organise l'espace. Des cartes imprimées permettent de visualiser les résultats de requêtes, d'ailleurs imaginées au préalable pour construire les outils. Cet examen des données, par le biais d'une géodatabase, permet également d'évaluer tout l'intérêt des outils informatiques pour la recherche. / This study is a spatial analysis of the archaeological remains dating from the origins to the end of the Old Kingdom of the funerary complexes of Netjerikhet and Sekhemkhet at Saqqara. The aim of this work is to understand the spatial occupation, the challenge is to process the very large amount of information from publications. To include all of the documentation to be processed, a database and a geographic information system (GIS) have been created. With these software tools, all artefacts were thus recorded and an analysis of the relationships between the different entities listed has been conducted to try to understand how the space is organized. Printed maps allow visualizing query results, queries moreover imagined beforehand to build the tools. This examination of the data through a geodatabase also assesses the interest of these tools for research.
