This book was released on 1991 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le travail présenté dans ce mémoire concerne la localisation d'un système de vision monoculaire dans des scènes, a partir de la connaissance de leur modèle géométrique, même partiel, et d'une séquence d'images de luminance. La procédure générale adoptée consiste d'abord en une mise en correspondance automatique des arêtes rectilignes du modèle et des segments de droite extraits des images des scènes observées, et ensuite en une interprétation tridimensionnelle des appariements ainsi sélectionnés. La première partie du mémoire est constituée d'un chapitre consacré a une étude bibliographique sur la psychologie et la perception visuelle chez l'homme. Elle présente des notions utiles pour la conception de systèmes de vision artificielle. La seconde partie comprend quatre chapitres qui exposent dans le détail les prétraitements effectués sur les images, les méthodes algébriques ou algorithmiques d'interprétation tridimensionnelle d'indices visuels (n-uplets de droites, ellipses), les outils développés pour les mises en correspondance automatique, et le filtrage des appariements potentiels. Les procédures de localisation permettent de calculer le point de prise de vue dans les cas de faibles ou de forts déplacements de la caméra entre deux prises d'image. Deux exemples de localisation pour la navigation ou la poursuite (tracking) sont inclus dans ce chapitre. Les points forts et les faiblesses actuelles du logiciel Ulysse de simulation, conçu et construit pour une application a la navigation par localisation visuelle d'un robot mobile dans une centrale nucléaire, sont discutes dans la conclusion de ce mémoire.

This book was released on 2002 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le présent travail porte sur la localisation incrémentale et absolue d'un robot mobile dans un environnement d'intérieur partiellement modélisé en utilisant la vision monoculaire. L'environnement de navigation du robot est à base de primitives géométriques (segments). Il intègre la notion d'occultation grâce à un découpage de l'espace 2-D navigable en Régions d'Invariance Visuelle. Le modèle de caméra à perspective pleine est obtenu grâce au calibrage par la méthode de Zhang. L'approche adoptée est composée de quatre étapes : acquisition d'une image à partir de la position courante du robot, extraction des primitives observées, mise en correspondance des primitives de l'image avec celle du modèle et calcul de la position et de l'orientation de la caméra. Deux méthodes numériques de calcul de la position et de l'orientation de la caméra grâce à des correspondances de droites sont présentées et adaptées au cas spécifique de la robotique mobile. Enfin, un algorithme de mise en correspondance des segments de l'image avec ceux du modèle est défini. Il est basé sur la recherche dans un arbre d'interprétation. Les Régions d'Invariance Visuelle et la configuration du système sont utilisées pour réduire l'espace des correspondances. Des contraintes géométriques d'ordre un et deux sont définies pour assurer l'élagage rapide de l'arbre. Une nouvelle fonction de vérification de la cohérence globale permet de sélectionner l'hypothèse de correspondance la plus cohérente.

Download or read book An Introduction to 3D Computer Vision Techniques and Algorithms written by Boguslaw Cyganek and published by John Wiley & Sons. This book was released on 2011-08-10 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer vision encompasses the construction of integrated vision systems and the application of vision to problems of real-world importance. The process of creating 3D models is still rather difficult, requiring mechanical measurement of the camera positions or manual alignment of partial 3D views of a scene. However using algorithms, it is possible to take a collection of stereo-pair images of a scene and then automatically produce a photo-realistic, geometrically accurate digital 3D model. This book provides a comprehensive introduction to the methods, theories and algorithms of 3D computer vision. Almost every theoretical issue is underpinned with practical implementation or a working algorithm using pseudo-code and complete code written in C++ and MatLab®. There is the additional clarification of an accompanying website with downloadable software, case studies and exercises. Organised in three parts, Cyganek and Siebert give a brief history of vision research, and subsequently: present basic low-level image processing operations for image matching, including a separate chapter on image matching algorithms; explain scale-space vision, as well as space reconstruction and multiview integration; demonstrate a variety of practical applications for 3D surface imaging and analysis; provide concise appendices on topics such as the basics of projective geometry and tensor calculus for image processing, distortion and noise in images plus image warping procedures. An Introduction to 3D Computer Vision Algorithms and Techniques is a valuable reference for practitioners and programmers working in 3D computer vision, image processing and analysis as well as computer visualisation. It would also be of interest to advanced students and researchers in the fields of engineering, computer science, clinical photography, robotics, graphics and mathematics.

Download or read book Arabic Thought and Islamic Societies RLE Politics of Islam written by Aziz Al-Azmeh and published by Routledge. This book was released on 2013-07-18 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a study of the structure and composition of the official learning current in medieval Arabic culture. This comprises natural sciences both exoteric and esoteric (medicine, alchemy, astrology and others), traditional and religious sciences (such as theology, exegesis and grammar), philosophical sciences such as metaphysics and ethics, in addition to technical disciplines like political theory and medicine, and other fields of intellectual endeavour. The book identifies and develops a number of conceptual elements common to the various areas of official Arabic scientific discourse, and shows how these elements integrate these disparate sciences into an historical epistemic unity. The specific profile of each of these different sciences is described, in terms of its conceptual content, but especially with reference to its historical circumstances. These are seen to be embodied in a number of institutional supports, both intellectual and social: paradigms, schools of thought, institutions of learning, pedagogic techniques, and a body of professionals, all of which combine to form definite, albeit ever renewed, traditions of learning. Finally, an attempt is made to relate Arabic scientific knowledge in the Middle Ages to patterns of scientific and political authority. First published in 1986.

Available in PDF, EPUB and Kindle. Book excerpt: “We got to talking”—so David Antin begins the introduction to Radical Coherency, embarking on the pursuit that has marked much of his breathless, brilliantly conversational work. For the past forty years, whether spoken under the guise of performance artist or poet, cultural explorer or literary critic, Antin’s innovative observations have helped us to better understand everything from Pop to Postmodernism. Intimately wedded to the worlds of conceptual art and poetics, Radical Coherency collects Antin’s influential critical essays and spontaneous, performed lectures (or “talk pieces”) for the very first time, capturing one of the most distinctive perspectives in contemporary literature. The essays presented here range from the first serious assessment of Andy Warhol published in a major art journal, as well as Antin’s provocative take on Clement Greenberg’s theory of Modernism, to frontline interventions in present debates on poetics and fugitive pieces from the ’60s and ’70s that still sparkle today—and represent a gold mine for art historians of the period. From John Cage to Allan Kaprow, Mark Rothko to Ludwig Wittgenstein, Antin takes the reader on an idiosyncratic, personal journey through twentieth-century culture with his trademark antiformalist panache—one thatwill be welcomed by any fan of this consummate trailblazer.
Download or read book Foundations of Social Evolution written by Steven A. Frank and published by Princeton University Press. This book was released on 2019-12-31 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a masterly theoretical treatment of one of the central problems in evolutionary biology, the evolution of social cooperation and conflict. Steven Frank tackles the problem with a highly original combination of approaches: game theory, classical models of natural selection, quantitative genetics, and kin selection. He unites these with the best of economic thought: a clear theory of model formation and comparative statics, the development of simple methods for analyzing complex problems, and notions of information and rationality. Using this unique, multidisciplinary approach, Frank makes major advances in understanding the foundations of social evolution. Frank begins by developing the three measures of value used in biology--marginal value, reproductive value, and kin selection. He then combines these measures into a coherent framework, providing the first unified analysis of social evolution in its full ecological and demographic context. Frank also extends the theory of kin selection by showing that relatedness has two distinct meanings. The first is a measure of information about social partners, with close affinity to theories of correlated equilibrium and Bayesian rationality in economic game theory. The second is a measure of the fidelity by which characters are transmitted to future generations--an extended notion of heritability. Throughout, Frank illustrates his methods with many examples, including a complete reformulation of the theory of sex allocation. The book also provides a unique "how-to" guide for constructing models of social behavior. It is essential reading for evolutionary biologists and for economists, mathematicians, and others interested in natural selection.

Download or read book Between Literature and Science written by Wolf Lepenies and published by Cambridge University Press. This book was released on 1988 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The theme of this book is the conflict which arose in the early nineteenth century between, on the one hand, the literary and, on the other hand, the scientific intellectuals of Europe, as they competed for recognition as the chief analysts of the new industrial society in which they lived. This conflicts was epitomised by the confrontation between Matthew Arnold and T. H. Huxley, and later in that between F. R. Leavis and C. P. Snow. Sociology was born as the third major discipline, though in many ways it was a hybrid of the literary and the scientific traditions. The social sciences continue, even today, to oscillate between these two traditions. The author chronicles the rise of the new discipline by discussing the lives and work of the most prominent thinkers of the time, in England, France and Germany. These include John Stuart Mill, H. G. Wells, Beatrice and Sidney Webb and T. S. Eliot; Auguste Comte, Charles Peguy, Emile Durkheim; Stefan George, Thomas Mann, Max Weber and Karl Mannheim. At stake was the right to formulate a philosophy of life for contemporary society, and to predict and pre-empt the worst consequences of industrialization. The book presents a penetrating study of idealists grappling with reality, when industrial society was still in its infancy. It will be of interest to those studying sociology and its history as a discipline, but it is equally relevant to other social science subjects which may be said to have arisen at about the same time" -- Back cover.
