Available in PDF, EPUB and Kindle. Book excerpt: For several decades researchers have tried to construct perception systems based on the registration data from video cameras. This work has produced various tools that have made recent advances possible in this area. Part 1 of this book deals with the problem of the calibration and auto-calibration of video captures. Part 2 is essentially concerned with the estimation of the relative object/capture position when a priori information is introduced (the CAD model of the object). Finally, Part 3 discusses the inference of density information and the shape recognition in images.

Available in PDF, EPUB and Kindle. Book excerpt: L'OBJECTIF DE CETTE THESE EST DE SYNTHETISER DE NOUVELLES VUES D'UNE SCENE 3D A PARTIR DE VUES EXISTANTES. UNE PREMIERE APPROCHE CONSISTE A CONSTRUIRE UN MODELE 3D UNIQUE, DONT LE RENDU S'EFFECTUE DE MANIERE CLASSIQUE. MALHEUREUSEMENT, LA CONSTRUCTION D'UN TEL MODELE DANS UN CONTEXTE GENERAL SANS INTERVENTION MANUELLE EST UNE UTOPIE, ESSENTIELLEMENT A CAUSE DES PROBLEMES MAL POSES DE LA MISE EN CORRESPONDANCE ET DE LA RECONSTRUCTION. UNE AUTRE APPROCHE, PLUS REALISTE, CONSISTE ALORS A REPRESENTER LA SCENE PAR LA COLLECTION D'IMAGES DONNEE AU DEPART, ET A Y PRELEVER ET PROJETER DIRECTEMENT LA TEXTURE DANS L'IMAGE A SYNTHETISER EN FONCTION DE LA POSITION DE L'OBSERVATEUR. UN NOUVEAU SYSTEME DE RENDU-BASE IMAGE A ETE DEVELOPPE ET TROIS CONTRIBUTIONS MAJEURES ONT ETE APPORTEES. LA PREMIERE EST UNE METHODE DE MISE EN CORRESPONDANCE QUASI-DENSE. DES POINTS REMARQUABLES SONT D'ABORD APPARIES PUIS SERVENT DE GERMES POUR DES CROISSANCES DE REGIONS QUI TENDENT A DENSIFIER LES CORRESPONDANCES ENTRE PIXELS SELON UNE STRATEGIE MEILLEUR D'ABORD. LES ZONES OU LA LUMINANCE VARIE FAIBLEMENT NE SONT PAS APPARIEES, MAIS LES DISPARITES ET ZONES PARTIELLEMENT OCCULTEES IMPORTANTES SONT PERMISES. LA SECONDE EST UNE METHODE DE TRIANGULATIONS CONJOINTES DANS LES IMAGES DONT L'OBJECTIF EST LA SYNTHESE DANS UN VOISINAGE DES POINTS DE VUES DONNES. L'OBJECTIF EST A LA FOIS DE SIMPLIFIER LA MISE EN CORRESPONDANCE LA OU ELLE EXISTE, DE LA COMPLETER AILLEURS, ET DE MODELISER EXPLICITEMENT DANS L'ESPACE IMAGE L'INFORMATION DE VISIBILITE PAR MISE EN CORRESPONDANCE DES SOMMETS ET DES ARETES CONTRAINTES. UNE METHODE D'ESTIMATION DE GEOMETRIE ENTRE PLUSIEURS CAMERAS EST FINALEMENT PROPOSEE. COMME ELLE S'APPUIE SUR UNE MISE EN CORRESPONDANCE QUASI-DENSE, MIEUX REPARTIE DANS L'ESPACE IMAGE QUE DES POINTS D'INTERETS APPARIES, UNE MEILLEURE PRECISION ET INCERTITUDE SONT OBTENUES. TOUTES CES METHODES ONT ETE TESTEES SUR DES IMAGES REELLES.

Available in PDF, EPUB and Kindle. Book excerpt: La localisation est un problème récurrent de la vision par ordinateur, avec des applications dans des domaines multiples tels que la robotique ou la réalité augmentée. Dans cette thèse on considère en particulier le problème d'initialisation de la pose, c'est-à-dire la localisation sans information a priori sur la position de la caméra. Nous nous intéressons à la localisation à partir d'une image monoculaire et d'un nuage de points reconstruit à partir d'une séquence d'images. Puisque nous n'avons pas d'a priori sur la position de la caméra, l'estimation de la pose s'appuie sur la recherche de correspondances entre des points de l'image et des points du modèle de la scène. Cette mise en correspondance est difficile en raison de sa combinatoire élevée. Elle peut être mise en défaut lorsque l'image dont on cherche la pose est très différente de celles ayant servi à la construction du modèle, en particulier en présence de forts changements de point de vue. Cette thèse développe une approche permettant la mise en correspondance image-modèle dans ces situations complexes. Elle consiste à synthétiser localement l'apparence de la scène à partir de points de vue virtuels puis à ajouter au modèle des descripteurs extraits des images synthétisées. Comme le modèle de scène est un nuage de points, la synthèse n'est pas faite par rendu 3D mais utilise des transformations 2D locales des observations connues de la scène. Les contributions suivantes sont apportées. Nous étudions différents modèles de transformation possibles et montrons que la synthèse par homographie est la plus adaptée pour ce type d'application. Nous définissons une méthode de positionnement des points de vue virtuels par rapport à une segmentation de la scène en patchs plans. Nous assurons l'efficacité de l'approche proposée en ne synthétisant que des vues utiles : elles sont éloignées de celles existantes et elles ne se recouvrent pas. Nous vérifions également que la scène est visible à partir des points des vue virtuels pour ne pas produire des vues aberrantes à cause d'occultations. Enfin, nous proposons une méthode de recherche de correspondances image-modèle qui est à la fois rapide et robuste. Cette méthode exploite la répartition non-uniforme des correspondances correctes dans le modèle, ce qui permet de guider leur recherche. Les résultats expérimentaux montrent que la méthode proposée permet de calculer des poses dans des configurations défavorables où les approches standard échouent. De façon générale la précision des poses obtenues augmente significativement lorsque la synthèse de vue est utilisée. Enfin nous montrons que, en facilitant la mise en correspondance image-modèle, cette méthode accélère le calcul de pose.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book excerpt: Now available in paperback for the first time, this classic work presents a cognitive-semiotic framework for understanding how maps work as powerful, abstract, and synthetic spatial representations. Explored are the ways in which the many representational choices inherent in mapping interact with information processing and knowledge construction, and how the resulting insights can be used to make informed symbolization and design decisions. A new preface to the paperback edition situates the book within the context of contemporary technologies. As the nature of maps continues to evolve, Alan MacEachren emphasizes the ongoing need to think systematically about the ways people interact with and use spatial information.

This book was released on 2006 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a wide class of novel and efficient adaptive signal processing techniques developed to restore signals from noisy and degraded observations. These signals include those acquired from still or video cameras, electron microscopes, radar, X-rays, or ultrasound devices, and are used for various purposes, including entertainment, medical, business, industrial, military, civil, security, and scientific. In many cases useful information and high quality must be extracted from the imaging. However, often raw signals are not directly suitable for this purpose and must be processed in some way. Such processing is called signal reconstruction. This book is devoted to a recent and original approach to signal reconstruction based on combining two independent ideas: local polynomial approximation and the intersection of confidence interval rule.

Book excerpt: NEW YORK TIMES BESTSELLER • “A fascinating look at how consumers perceive logos, ads, commercials, brands, and products.”—Time How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? In Buyology, Martin Lindstrom presents the astonishing findings from his groundbreaking three-year, seven-million-dollar neuromarketing study—a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what captures our interest—and drives us to buy. Among the questions he explores: • Does sex actually sell? • Does subliminal advertising still surround us? • Can “cool” brands trigger our mating instincts? • Can our other senses—smell, touch, and sound—be aroused when we see a product? Buyology is a fascinating and shocking journey into the mind of today's consumer that will captivate anyone who's been seduced—or turned off—by marketers' relentless attempts to win our loyalty, our money, and our minds.

Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing is one of the main foundations of archaeological data, underpinning knowledge and understanding of the historic environment. The volume, arising from a symposium organised by the Europae Archaeologiae Consilium (EAC) and the Aerial Archaeology Research Group (AARG), provides up to date expert statements on the methodologies, achievements and potential of remote sensing with a particular focus on archaeological heritage management. Well-established approaches and techniques are set alongside new technologies and data-sources, with discussion covering relative merits and applicability, and the need for integrated approaches to understanding and managing the landscape. Discussions cover aerial photography, both modern and historic, LiDAR, satellite imagery, multi- and hyper-spectral data, sonar and geophysical survey, addressing both terrestrial and maritime contexts. Case studies drawn from the contrasting landscapes of Europe illustrate best practice and innovative projects.

Book excerpt: This book documents and describes 32 natural caves from France and around the globe that have a width larger than 50 m, including data on the largest underground chamber in the world: Sarawak Chamber. Artificial caves are not able to be constructed at these volumes and most of these naturally forming chambers had never been surveyed before with little geological data available. Methodologies for studying these large volume Karst chambers are described and for each site, a survey, a geomorphological sketch, a description and photographic images are provided. The process of the mechanical transportation by underground running water, of an insoluble but erodible rock located below thick limestone roofs via digging, scouring and racking are explained through these example to clarify the genesis of the largest volumes in the world. The purpose of this study was to estimate whether these natural contexts could be transposed to the digging of artificial caverns to accommodate underground nuclear power plants. Indeed, the comparison of the effects of the Lucens nuclear accident with those of Chernobyl and Fukushima shows the whole interest of an underground solution. These examples of natural chambers indisputably show that this is possible.

Available in PDF, EPUB and Kindle. Book excerpt: Contemporary Criminological Issues tackles some of today’s most pressing social issues, from the criminalization of Indigenous peoples to interpersonal violence, border control, and armed conflicts. This book advances cutting-edge theories and methods, with the aim of moving beyond the scholarship that reproduces insecurity and exclusion. The breadth of approaches encompasses much of the current critical criminological scholarship, serving as a counterpoint to the growth of managerial and administrative criminologies and the rise of explicitly exclusionary and punitive state policies and practices with respect to ‘crime’ and ‘security.’ This edited collection featuring two books, one in English and one in French, includes important contributions to knowledge and public policy by eminent experts and emerging scholars. This book is published in English.
