Available in PDF, EPUB and Kindle. Book excerpt: Le suivi d’objet dans les séquences d’images est un axe de recherche assez développé dans le domaine de la vision artificielle. Il peut être vu comme un processus composé de deux phases : la phase d'initialisation ou de segmentation dans laquelle nous définissons dans l'image l'objet à suivre, et la phase de suivi pendant laquelle nous recherchons l'objet dans les images successives.Quatre approches de suivi d’objet ont été étudiées et implémentées, puis optimisées par rapport à leurs versions trouvées classiquement dans la littérature. La première approche concerne la méthode des courbes de niveau, abordée autant comme approche de segmentation que de suivi. La deuxième approche permet de se placer dans un cadre bayésien et de formuler le suivi de manière probabiliste grâce à un filtrage particulaire. Dans la troisième approche, l'algorithme de CamShift est appliqué sur l’image avec un modèle de l’objet à suivre construit sur deux canaux de couleur au lieu des trois plus généralement utilisés. Enfin une quatrième approche combinant une mise en correspondance de points d’intérêt et l'algorithme de CamShift a été développée pour un fonctionnement dans des séquences d’images en niveaux de gris.Une évaluation de chaque approche sur quelques séquences d’images est menée afin d’explorer l'évolution d'un ensemble de mesures de performance avec des variations de paramètres. Un bilan comparatif a ensuite été réalisé afin de définir les avantages, inconvénients et conditions d’utilisation de chaque approche.Le cadre applicatif de ces travaux est le suivi d’un unique objet sans connaissance a priori ni phase d’apprentissage dans une séquence d’images en niveaux de gris en vue d’une implantation avec fonctionnement en temps réel sur un système embarqué.

Download or read book Invention of Hysteria written by Georges Didi-Huberman and published by MIT Press. This book was released on 2004-09-17 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first English-language publication of a classic French book on the relationship between the development of photography and of the medical category of hysteria. In this classic of French cultural studies, Georges Didi-Huberman traces the intimate and reciprocal relationship between the disciplines of psychiatry and photography in the late nineteenth century. Focusing on the immense photographic output of the Salpetriere hospital, the notorious Parisian asylum for insane and incurable women, Didi-Huberman shows the crucial role played by photography in the invention of the category of hysteria. Under the direction of the medical teacher and clinician Jean-Martin Charcot, the inmates of Salpetriere identified as hysterics were methodically photographed, providing skeptical colleagues with visual proof of hysteria's specific form. These images, many of which appear in this book, provided the materials for the multivolume album Iconographie photographique de la Salpetriere. As Didi-Huberman shows, these photographs were far from simply objective documentation. The subjects were required to portray their hysterical "type"—they performed their own hysteria. Bribed by the special status they enjoyed in the purgatory of experimentation and threatened with transfer back to the inferno of the incurables, the women patiently posed for the photographs and submitted to presentations of hysterical attacks before the crowds that gathered for Charcot's "Tuesday Lectures." Charcot did not stop at voyeuristic observation. Through techniques such as hypnosis, electroshock therapy, and genital manipulation, he instigated the hysterical symptoms in his patients, eventually giving rise to hatred and resistance on their part. Didi-Huberman follows this path from complicity to antipathy in one of Charcot's favorite "cases," that of Augustine, whose image crops up again and again in the Iconographie. Augustine's virtuosic performance of hysteria ultimately became one of self-sacrifice, seen in pictures of ecstasy, crucifixion, and silent cries.
Download or read book The Psychic Life of Power written by Judith Butler and published by Stanford University Press. This book was released on 1997 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Judith Butler's new book considers the way in which psychic life is generated by the social operation of power, and how that social operation of power is concealed and fortified by the psyche that it produces. It combines social theory, philosophy, and psychoanalysis in novel ways, and offers a more sustained analysis of the theory of subject formation implicit in her previous books.

This book was released on 1991-02-28 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: On October 14-19, 1990, the 6th International Conference on the Conservation of Earthen Architecture was held in Las Cruces, New Mexico. Sponsored by the GCI, the Museum of New Mexico State Monuments, ICCROM, CRATerre-EAG, and the National Park Service, under the aegis of US/ICOMOS, the event was organized to promote the exchange of ideas, techniques, and research findings on the conservation of earthen architecture. Presentations at the conference covered a diversity of subjects, including the historic traditions of earthen architecture, conservation and restoration, site preservation, studies in consolidation and seismic mitigation, and examinations of moisture problems, clay chemistry, and microstructures. In discussions that focused on the future, the application of modern technologies and materials to site conservation was urged, as was using scientific knowledge of existing structures in the creation of new, low-cost, earthen architecture housing.
Download or read book Field Geology of High Grade Gneiss Terrains written by Cees W. Passchier and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there are numerous publications on the geology of high-grade gneiss terrains, few descriptions exist of how to map and carry out structural analysis in these terrains. Textbooks on structural geology concentrate on technIques appli cable to low-grade terrains. Geologists who have no experience of mapping high-grade gneisses are often at a loss as to how to apply techniques to high grade rocks that were developed for low to medium grade metamorphic terrains. Any study of deep crustal processes and their development through time should begin with examination of the primary data source - outcrops of high grade metamorphic terrains. We feel that the urge to apply advanced techniques of fabric analysis, petrology, geochemistry, isotope geochemistry and age deter mination to these rocks often results in brief sampling trips in which there is little, if any analysis of the structural and metamorphic history revealed by outcrop patterns. Many studies of the metamorphic petrology and geochemistry of high-grade gneiss terrains make ineffective use of available field data, often because the authors are unaware of structural complexities and of the ways to recognise and use them. This is unfortunate, because much data can be collected in the field at minimal cost that cannot easily, if at all, be obtained from material in the laboratory. The primary igneous or sedimentary nature of a rock, the relative age of intrusive veins, and the sequence of deformation that they under went, can usually best be determined by straightforward observation in the field.
Download or read book Compressive Strength of Concrete written by Pavel Krivenko and published by BoD – Books on Demand. This book was released on 2020-03-11 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete made using mineral cements, the raw materials which on earth are practically endless, is known as one of the oldest building materials and during the last decades of the twentieth century has become a dominant building material for general use. At the same time, the requirements of the quality of concrete and its performance properties, in particular compressive strength, durability, economical efficiency, and low negative impact of its manufacture on the environment have not yet been completely met. Bearing these requirements in mind, researchers and engineers worldwide are working on how to satisfy these requirements. This book has been written by researchers and experts in the field and provides the state of the art on recent progress achieved on the properties of concrete, including concrete in which industrial by-products are utilized. The book is dedicated to graduate students, researchers, and practicing engineers in related fields.
Download or read book Pattern Recognition and Machine Learning written by Christopher M. Bishop and published by Springer. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first textbook on pattern recognition to present the Bayesian viewpoint. The book presents approximate inference algorithms that permit fast approximate answers in situations where exact answers are not feasible. It uses graphical models to describe probability distributions when no other books apply graphical models to machine learning. No previous knowledge of pattern recognition or machine learning concepts is assumed. Familiarity with multivariate calculus and basic linear algebra is required, and some experience in the use of probabilities would be helpful though not essential as the book includes a self-contained introduction to basic probability theory.

Available in PDF, EPUB and Kindle. Book excerpt: Research on the multifaceted aspects of modeling, analysis, and synthesis of - man gesture is receiving growing interest from both the academic and industrial communities. On one hand, recent scienti?c developments on cognition, on - fect/emotion, on multimodal interfaces, and on multimedia have opened new perspectives on the integration of more sophisticated models of gesture in c- putersystems.Ontheotherhand,theconsolidationofnewtechnologiesenabling “disappearing” computers and (multimodal) interfaces to be integrated into the natural environments of users are making it realistic to consider tackling the complex meaning and subtleties of human gesture in multimedia systems, - abling a deeper, user-centered, enhanced physical participation and experience in the human-machine interaction process. The research programs supported by the European Commission and s- eral national institutions and governments individuated in recent years strategic ?elds strictly concerned with gesture research. For example, the DG Infor- tion Society of the European Commission (www.cordis.lu/ist) supports several initiatives, such as the “Disappearing Computer” and “Presence” EU-IST FET (Future and Emerging Technologies), the IST program “Interfaces & Enhanced Audio-Visual Services” (see for example the project MEGA, Multisensory - pressive Gesture Applications, www.megaproject.org), and the IST strategic - jective “Multimodal Interfaces.” Several EC projects and other funded research are represented in the chapters of this book.

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.
