This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans le cadre de l'acquisition de l'information de profondeur de scènes texturées, un processus d'estimation de la profondeur basé sur la méthode de reconstruction 3D « Shape from Focus » est présenté dans ce manuscrit. Les deux étapes fondamentales de cette approche sont l'acquisition de la séquence d'images de la scène par sectionnement optique et l'évaluation de la netteté locale pour chaque pixel des images acquises. Deux systèmes d'acquisition de cette séquence d'images sont présentés ainsi que les traitements permettant d'exploiter celle-ci pour la suite du processus d'estimation de la profondeur. L'étape d'évaluation de la netteté des pixels passe par la comparaison des différents opérateurs de mesure de netteté. En plus des opérateurs usuels, deux nouveaux opérateurs basés sur les descripteurs généralisés de Fourier sont proposés. Une méthode nouvelle et originale de comparaison est développée et permet une analyse approfondie de la robustesse à différents paramètres des divers opérateurs. Afin de proposer une automatisation du processus de reconstruction, deux méthodes d'évaluation automatique de la netteté sont détaillées. Finalement, le processus complet de reconstruction est appliqué à des scènes agronomiques, mais également à une problématique du domaine de l'analyse de défaillances de circuits intégrés afin d'élargir les domaines d'utilisation

Book Synopsis Modélisation D'Images Agronomiques by : Gawain Jones
Download or read book Modélisation D'Images Agronomiques written by Gawain Jones and published by Omniscriptum. This book was released on 2017-11-10 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les réglementations concernant les usages de produits phytosanitaires en agriculture ont conduit à la mise au point de méthodes d'identification de plantes pour une gestion des adventices. Afin de disposer d'un outil permettant l'évaluation de ces méthodes spatiales, un modèle de simulation de scènes agronomiques a été mis au point. Prenant en considération les caractéristiques agronomiques d'une parcelle, il permet de simuler une vérité terrain dont les paramètres sont contrôlés. La scène ainsi créée subit ensuite une transformation projective afin de simuler la prise de photographie. Ce modèle a ensuite été validé à l'aide de comparaison statistique avec des données réelles. Des algorithmes basés sur la Transformée de Hough ont été développés. Trois méthodes (analyse en composante connexe, estimation de contours et méthode probabiliste) ont été mises en oeuvre et évaluées avec des taux de classification correcte compris entre 90% et 98%. Enfin, pour ce modèle, une approche spectrale a été explorée afin de dépasser les limitations des méthodes spatiales. Une extension 3D a été apportée afin de permettre la simulation de la réflectance bidirectionnelle (BRDF) des plantes et du sol.
Book Synopsis Heritage Sites of Astronomy and Archaeoastronomy in the Context of the UNESCO World Heritage Convention by : Clive L. N. Ruggles
Download or read book Heritage Sites of Astronomy and Archaeoastronomy in the Context of the UNESCO World Heritage Convention written by Clive L. N. Ruggles and published by . This book was released on 2017-11-30 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This joint venture between ICOMOS, the advisory body to UNESCO on cultural sites, and the International Astronomical Union is the second volume in an ongoing exploration of themes and issues relating to astronomical heritage in particular and to science and technology heritage in general. It examines a number of key questions relating to astronomical heritage sites and their potential recognition as World Heritage, attempting to identify what might constitute "outstanding universal value" in relation to astronomy. "Heritage Sites of Astronomy and Archaeoastronomy--Volume 2" represents the culmination of several years' work to address some of the most challenging issues raised in the first ICOMOS-IAU Thematic Study, published in 2010. These include the recognition and preservation of the value of dark skies at both cultural and natural sites and landscapes; balancing archaeoastronomical considerations in the context of broader archaeological and cultural values; the potential for serial nominations; and management issues such as preserving the integrity of astronomical sightlines through the landscape.Its case studies are developed in greater depth than those in volume 1, and generally structured as segments of draft nomination dossiers. They include seven-stone antas (prehistoric dolmens) in Portugal and Spain, the thirteen towers of Chankillo in Peru, the astronomical timing of irrigation in Oman, Pic du Midi de Bigorre Observatory in France, Baikonur Cosmodrome in Kazakhstan, and Aoraki-Mackenzie International Dark Sky Reserve in New Zealand. A case study on Stonehenge, already a World Heritage Site, focuses on preserving the integrity of the solstitial sightlines.As for the first ICOMOS-IAU Thematic Study, a international team of authors including historians, astronomers and heritage professionals is led by Professor Clive Ruggles for the IAU and Professor Michel Cotte for ICOMOS.
Book Synopsis Jean-Baptiste Say and Political Economy by : Jean-Baptiste Say
Download or read book Jean-Baptiste Say and Political Economy written by Jean-Baptiste Say and published by Taylor & Francis. This book was released on 2016-11-10 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jean-Baptiste Say (1767–1832) was one of the first great economists to have laid down the foundations of economic science. Author of the famous Treatise on Political Economy in 1803, which was revised and re-edited on several occasions, he published numerous other works including a voluminous Complete Course in Practical Political Economy in 1828–9. He also taught political economy successively from 1815 until his death in three Parisian establishments: the Athénée, the Conservatory of Arts and Trades, and the Collège de France. The texts in which Say exposes his approach to political economy have not been available in the English language until now except for the fourth edition of the ‘Preliminary Discourse’ which serves as an introduction to the Treatise. This book presents a translation which renders his works accessible to the English speaking world. For the first time, English readers will be able to become directly immersed in Say’s principal texts, where he develops his conception of political economy. Jean-Baptiste Say and Political Economy proposes a translation of a selection of eleven of Say’s texts. The first three are versions of the ‘Preliminary Discourse’ from the Treatise’s editions of 1803, 1814 and 1826 with the variations of the editions of 1817, 1819 and 1841. The following four texts are the opening discourses pronounced at the Conservatory in 1820 and 1828 and the Collège de France in 1831 and 1832. The eighth text is the ‘General Considerations’ which open the Complete Course in Practical Political Economy of 1828, with the variations of the 1840 re-edition. The final three texts are those Say devotes to ‘the progress of political economy’ in what is akin to a history of economic thought. This volume is of great importance to economic historians and people studying Jean-Baptiste Say, as well as those who are interested in economic theory and philosophy and political economy.

Book Synopsis Water & Heritage by : Willem Willems
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

Book Synopsis Indigenous Men and Masculinities by : Robert Alexander Innes
Download or read book Indigenous Men and Masculinities written by Robert Alexander Innes and published by Univ. of Manitoba Press. This book was released on 2015-11-06 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: What do we know of masculinities in non-patriarchal societies? Indigenous peoples of the Americas and beyond come from traditions of gender equity, complementarity, and the sacred feminine, concepts that were unimaginable and shocking to Euro-western peoples at contact. "Indigenous Men and Masculinities", edited by Kim Anderson and Robert Alexander Innes, brings together prominent thinkers to explore the meaning of masculinities and being a man within such traditions, further examining the colonial disruption and imposition of patriarchy on Indigenous men. Building on Indigenous knowledge systems, Indigenous feminism, and queer theory, the sixteen essays by scholars and activists from Canada, the U.S., and New Zealand open pathways for the nascent field of Indigenous masculinities. The authors explore subjects of representation through art and literature, as well as Indigenous masculinities in sport, prisons, and gangs. "Indigenous Men and Masculinities" highlights voices of Indigenous male writers, traditional knowledge keepers, ex-gang members, war veterans, fathers, youth, two-spirited people, and Indigenous men working to end violence against women. It offers a refreshing vision toward equitable societies that celebrate healthy and diverse masculinities.
