Available in PDF, EPUB and Kindle. Book excerpt: Omniprésents, la relation homme-machine est encore une définition ardue à cerner. Les ordinateurs réalisent dans le temps des tâches récurrentes. Ils aident ainsi l'homme à manipuler d'énormes quantités de données, souvent même plus rapidement et plus précisément que lui. Malgré cela, la capacité des ordinateurs demeure limitée lorsqu'il s'agit d'extraire automatiquement des informations d'images ou de vidéos, qui représentent pourtant des volumes de données extrêmement importants. La vision par ordinateur est un domaine qui inclut des méthodes d'acquisition, de traitement, d'analyse et de compréhension des images afin de produire de l'information numérique ou symbolique. Un axe de recherche contribuant au développement de ce domaine consiste à reproduire les capacités de la vision humaine par voie électronique afin de percevoir et de comprendre une image. Il s'agit de développer des algorithmes qui reproduisent une des capacités les plus étonnantes du cerveau humain à savoir la déduction des propriétés du monde purement externe au moyen de la lumière qui nous revient des divers objets qui nous entourent. Nos travaux de thèse s'inscrivent dans cet axe de recherche. Nous proposons plusieurs contributions originales s'inscrivant dans le cadre de résolution des problèmes de la reconnaissance et de la localisation des symboles graphiques en contexte. L'originalité des approches proposées réside dans la proposition d'une alliance intéressante entre l'Analyse Formelle de Concepts et la vision par ordinateur. Pour ce faire, nous nous sommes confrontés à l'étude du domaine de l'AFC et plus précisément l'adaptation de la structure du treillis de concepts et son utilisation comme étant l'outil majeur de nos travaux. La principale particularité de notre travail réside dans son aspect générique vu que les méthodes proposées peuvent être alliées à divers outils autre que le treillis de concepts en gardant les mêmes stratégies adoptées et en suivant une procédure semblable. Notre incursion dans le domaine de l'Analyse Formelle de Concepts et plus précisément notre choix de la structure du treillis de Galois appelé aussi treillis de concepts est motivé par les nombreux avantages présentés par cet outil. Le principal avantage du treillis de concepts est l'aspect symbolique qu'il offre. Il présente un espace de recherche concis, précis et souple facilitant ainsi la prise de décision. Nos contributions sont inscrites dans le cadre de la reconnaissance et de localisation de symboles dans les documents graphiques. Nous proposons des chaînes de traitement s'inscrivant dans le domaine de la vision par ordinateur.

Download or read book Reconnaissance de formes et symboles graphiques complexes dans les images de documents written by Rashid Jalal Qureshi and published by . This book was released on 2008 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail de thèse se situe à la croisée de trois thématiques de recherche : la mise en place de représentations structurelles pour décrire le contenu d’images de documents, la reconnaissance structurelle des formes et graphiques complexes et la localisation des symboles dans les images de documents. Pour répondre aux problématiques de l’analyse d’images de documents, nous avons choisi d’utiliser les graphes comme outils de représentation des contenus des images. La nouvelle représentation obtenue exploite un graphe multi-primitive et multi-attribut améliorant à la fois la tâche de localisation mais aussi la tâche de reconnaissance de formes graphiques contenues dans les documents. Une nouvelle approche générique et automatique est également présentée pour la localisation des symboles graphiques dans les images de documents. Notre approche de localisation des symboles nécessite un minimum de connaissances a priori sur les domaines ou sur le type de symboles présents dans les images. Concernant l’étape de reconnaissance, nous présentons trois stratégies originales pour la mise en correspondance de graphes, combinant les approches structurelle et statistique. Elles aident à la résolution du problème de complexité et évitent un temps de calcul exponentiel intolérable. Les nouvelles techniques d’appariement de graphes que nous proposons sont basées sur des fonctions de similarité qui tilisent aussi bien des valeurs numériques que symboliques pour produire un score. Ces mesures de similarité ont de nombreuses propriétés intéressantes comme un fort pouvoir discriminant, une invariance aux transformations affines et une faible sensibilité au bruit.

Download or read book Social Innovations in the Urban Context written by Taco Brandsen and published by Springer. This book was released on 2016-04-05 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the practice of social innovation, which is currently very much in the public eye. New ideas and approaches are needed to tackle the severe and wicked problems with which contemporary societies are struggling. Especially in times of economic crisis, social innovation is regarded as one of the crucial elements needed to move forward. Our knowledge of its dynamics has significantly progressed, thanks to an abundance of studies on social innovation both general and sector-specific. However, despite the valuable research conducted over the past years, the systematic analysis of social innovation is still contested and incomplete. The questions asked in the book will be the following: 1. What is the nature of social innovations? 2.What patterns can be identified in social innovations emerging at the local level? 3.How is the emergence and spread of social innovations related to urban governance? More precisely, which conditions and arrangements facilitate and hinders social innovation? We explore these questions using different types of data and methods, and studying different contexts. In particular, we focus on innovations that aim at solving problems of the young unemployed, single parents and migrants. This analysis is based on original research carried out in the period 2010-2013 in the framework of a European project with a specific empirical research strategy. Research was carried out in 20 cities in 10 different European countries.

Download or read book Harun Farocki written by Thomas Elsaesser and published by Amsterdam University Press. This book was released on 2004 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filmmaker, film essayist, installation artist, writer: the Berlin artist Harun Farocki has devoted his life to the power of images. Over the thirty-plus years of his career, Farocki has explored not the images of life but rather the life of images that surrounds us in newspapers, cinema, books, television, and advertising. Harun Farocki examines, from different critical perspectives, his vast oeuvre, which includes three feature films, critical media pieces, children’s television features, “learning films” in the tradition of Brecht, and installation pieces. Interviews, a selection of Farocki’s own writings, and an annotated filmography complete a valuable biography of this pioneering artist and his legendary career.

Download or read book Water Heritage written by Willem Willems and published by . This book was released on 2017-01-15 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects

Download or read book Advances in Low Level Color Image Processing written by M. Emre Celebi and published by Springer Science & Business Media. This book was released on 2013-12-17 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Color perception plays an important role in object recognition and scene understanding both for humans and intelligent vision systems. Recent advances in digital color imaging and computer hardware technology have led to an explosion in the use of color images in a variety of applications including medical imaging, content-based image retrieval, biometrics, watermarking, digital inpainting, remote sensing, visual quality inspection, among many others. As a result, automated processing and analysis of color images has become an active area of research, to which the large number of publications of the past two decades bears witness. The multivariate nature of color image data presents new challenges for researchers and practitioners as the numerous methods developed for single channel images are often not directly applicable to multichannel ones. The goal of this volume is to summarize the state-of-the-art in the early stages of the color image processing pipeline.

Download or read book Divine Names on the Spot written by Fabio Porzia and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Ancient Greek and Semitic languages resorted to a large range of words to name the divine. Gods and goddesses were called by a variety of names and combinations of onomastic attributes. This broad lexicon of names is characterised by plurality and a tendency to build on different sequences of names; therefore, the Mapping Ancient Polytheisms project focuses on the process of naming the divine in order to better understand the ancient divine in terms of a plurality in the making. A fundamental rule for reading ancient divine names is to grasp them in their context - time and place, a ritual, the form of the discourse, a cultural milieu...: a deity is usually named according to a specific situation. From Artemis Eulochia to al-Lat, al-'Uzza and Manat, from Melqart to "my rock" in the biblical book of Psalms, this volume journeys between the sanctuary on Mount Gerizim and late antique magical practices, revisiting rituals, hymnic poetry, oaths of orators and philosophical prayers. While targeting different names in different contexts, the contributors draft theoretical propositions towards a dynamic approach of naming the divine in antiquity.'

Download or read book The European Landscape Convention written by Michael Jones and published by Springer Science & Business Media. This book was released on 2011-02-09 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important and insightful book provides, for the first time, a broad presentation of ongoing research into public participation in landscape conservation, management and planning, following the 2000 European Landscape Convention which came into force in 2004. The book examines both the theory of participation and what lessons can be learnt from specific European examples. It explores in what manner and to what extent the provisions for participation in the European Landscape Convention have been followed up and implemented. It also presents and compares different experiences of participation in selected countries from northern, southern, eastern and western Europe, and provides a critical examination of public participation in practice. However, while the book’s focus is necessarily on Europe, many of the conclusions drawn are of global relevance. The book provides a valuable reference for researchers and advanced students in landscape policies and management, as well as for professionals and others interested in land-use planning and environmental management.
