Available in PDF, EPUB and Kindle. Book excerpt: La représentation d'une image numérique par un tableau de pixels n'est pas une information assez hiérarchique pour l'analyse d'images. Observant que le contraste importe bien moins que la géométrie, nous représentons cette information géométrique par les composantes connexes d'ensembles de niveaux dont nous remplissons les trous, la hiérarchie s'obtenant alors naturellement par l'ordre d'inclusion. La propriété attrayante de ces caractéristiques est qu'elles représentent exactement l'image. Deux filtres morphologiques déduits de cette représentation sont proposés. Puisqu'ils reposent sur cette représentation, ils présentent la propriété intéressante d'être invariants par inversion du contraste : on les qualifie d'autoduaux dans le vocabulaire de la morphologie mathématique. Nous utilisons ensuite cette représentation dans la deuxième partie pour traiter de l'un des problèmes les plus élémentaires en traitement de plusieurs images : le recalage. Notre méthode repose sur les éléments de base de notre représentation, nommés formes, qui sont donc des caractéristiques stables pour effectuer le recalage. Nous cherchons les formes de chaque image dans l'autre image, établissant ainsi des correspondances entre formes d'une image et de l'autre image. Puis une procédure de vote des correspondances sélectionne le mouvement dominant. Nous montrons que cette méthode a le mérite de donner un recalage d'une précision subpixellique dans des conditions tout à fait défavorables.

Download or read book Local Approximation Techniques in Signal and Image Processing written by Vladimir I︠A︡kovlevich Katkovnik and published by SPIE-International Society for Optical Engineering. 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.
Download or read book Fundamentals of Spatial Data Quality written by Rodolphe Devillers and published by John Wiley & Sons. This book was released on 2010-01-05 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains the concept of spatial data quality, a key theory for minimizing the risks of data misuse in a specific decision-making context. Drawing together chapters written by authors who are specialists in their particular field, it provides both the data producer and the data user perspectives on how to evaluate the quality of vector or raster data which are both produced and used. It also covers the key concepts in this field, such as: how to describe the quality of vector or raster data; how to enhance this quality; how to evaluate and document it, using methods such as metadata; how to communicate it to users; and how to relate it with the decision-making process. Also included is a Foreword written by Professor Michael F. Goodchild.

Download or read book Elusive Consumption written by Karin M. Ekström and published by Routledge. This book was released on 2020-05-27 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of rising consumerism and globalization, books on consumption are numerous. These tend to be firmly rooted in particular disciplines, however sociology, anthropology, business or cultural studies and as a result often present a blinkered view. Charged with the mission of unravelling what consumption means and how it operates, the worlds leading experts were flown to a secluded location in Sweden to 'battle it out'. This pioneering book represents the outcome. Ranging from the 'little black dress' to on-line communities, Elusive Consumption challenges our very understanding of consumerism. How successful is the advertising world in manipulating our buying patterns? Does the global marketplace promote cultural homogeneity or heterogeneity? Is the West really more of a 'consumerist civilization' than other countries? Does the advertising of certain products influence a voters choice of political party? How are products associated and marketed to different genders? These controversial topics and many more are discussed. Covering virtually every aspect of the word 'consumerism', Elusive Consumption provides a state-of-the-art view of the highly commercialized society we inhabit today. Some might have it that consumers are unwitting pawns, completely lacking in agency. Others might argue that consumer choices are empowering and subtly shape production. Richard Wilk, Colin Campbell, John F. Sherry, Richard Elliott, Russell Belk, and Daniel Miller who offers the most persuasive argument in this battle royal?

Download or read book Groundwater Modelling in Arid and Semi Arid Areas written by Howard S. Wheater and published by Cambridge University Press. This book was released on 2010-09-09 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography.

Download or read book Consumption Food and Taste written by Alan Warde and published by SAGE. This book was released on 1997-02-17 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring the expression of taste through the processes of consumption this book provides an incisive and accessible evaluation of the current theories of consumption, and trends in the representation and purchase of food. Alan Warde outlines various theories of change in the twentieth century, and considers the parallels between their diagnoses of consumer behaviour and actual trends in food practices. He argues that dilemmas of modern practical life and certain imperatives of the culture of consumption make sense of food selection. He suggests that contemporary consumption is best viewed as a process of continual selection among an unprecedented range of generally accessible items which are made available both commercially and informally.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive view of the most recent major international research in the field of tolerancing, and is an excellent resource for anyone interested in Computer Aided Tolerating. It is organized into 4 parts. Part 1 focuses on the more general problems of tolerance analysis and synthesis, for tolerancing in mechanical design and manufacturing processes. Part 2 specifically highlights the simulation of assembly with defects, and the influence of tolerances on the quality of the assembly. Part 3 deals with measurement aspects, and quality control throughout the life cycle. Different measurement technologies and methods for estimating uncertainty are considered. In Part 4, different aspects of tolerancing and their interactions are explored, from the definition of functional requirement to measurement processes in a PLM approach.
