Available in PDF, EPUB and Kindle. Book excerpt: L'objectif habituel d'une méthode de segmentation d'image bidimensionnelle est de déterminer une seule description plane sous la forme d'une partition de l'image en régions mutuellement exclusives. Nous mettons en évidence certaines limites intrinsèques de cette formulation et proposons de lui substituer un objectif multi-échelles: déterminer toute une famille de descriptions à niveau de détail variable, niveau réglé par un paramètre dit d'"échelle", qui est continu, contrairement aux descriptions pyramidales classiques. Nous avons baptisé une telle famille une description ensembles-échelle d'une image car elle constitue l'analogue ensembliste des descriptions espace-échelle (scale-space) issues du domaine du filtrage. Deux approches sont proposées pour obtenir des descriptions ensembles-échelle. La première s'appuie sur la théorie des graphes et aboutit à un point de vue nouveau sur une famille classique de méthodes de groupement hiérarchique. La seconde approche - la plus riche - résulte d'un mariage entre méthodes énergétiques et structurelles. Dans la lignée des approches variationnelles, bayésiennes ou par codage minimal de la segmentation, nous abordons la question comme un problème de modélisation optimale de l'image. Le paramètre d'échelle traduit alors l'existence d'un compromis inhérent à tout problème de modélisation de données : le compromis entre la " simplicité " du modèle et sa " fidélité " aux données. Nous mettons en évidence une équivalence entre ces formulations énergétiques classiques et des problèmes de débit/distorsion opérationnel qui interviennent dans le cadre de la compression de données avec pertes. L'approche proposée consiste alors à rechercher simultanément toutes les solutions de ce type de problème, pour toutes les " échelles " et aboutit à un principe d'optimisation - baptisé principe d'escalade - qui produit des descriptions ensembles-échelles remarquables associées à la définition d'un couple d'énergies antagonistes. L'algorithme obtenu est efficace et exempt de paramètre. Outre d'importantes propriétés théoriques (covariance d'échelle, identité de solution pour les deux problèmes duaux de débit/distorsion), la description produite possède de nombreux intérêts pratiques : sélection interactive ou automatique de partitions ou de régions pertinentes pour une application donnée, extraction des régions stables en échelle - qui représentent les formes les plus saillantes de l'image pour l'énergie considérée - caricature progressive d'images, compression, etc. De nombreux résultats expérimentaux illustrent la pertinence de la méthode pour l'analyse d'images variées (images naturelles, images d'observation de la Terre, IRM, images de distance).
Download or read book Inselbergs written by S. Porembski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inselbergs are isolated rock outcrops that stand out abruptly from surrounding plains. Despite the widespread occurrence of granite inselbergs throughout all climatic and vegetational zones, their remarkably rich plant life was largely neglected in the recent literature. This richly and partly in color illustrated volume provides a detailed survey of all major abiotic and biotic features characteristic for inselbergs. The extreme environmental conditions on inselbergs are described in depth as well as specific adaptive traits of rock outcrop plants including their morphological, anatomical and physiological responses. The diversity and structure of inselberg plant communities are examined on a global scale with detailed regional accounts for different tropical and temperate zones.
Download or read book Coviability of Social and Ecological Systems Reconnecting Mankind to the Biosphere in an Era of Global Change written by Olivier Barrière and published by Springer. This book was released on 2019-03-12 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second volume is the work of more than 55 authors from 15 different disciplines and includes complex systems science which studies the viability of components, and also the study of empirical situations. As readers will discover, the coviability of social and ecological systems is based on the contradiction between humanity, which adopts finalized objectives, and the biosphere, which refers to a ecological functions. We see how concrete situations shed light on the coviability’s determinants, and in this book the very nature of the coviability, presented as a concept-paradigm, is defined in a transversal and ontological ways. By adopting a systemic approach, without advocating any economic dogma (such as development) or dichotomizing between humans and nature, while emphasizing what is relevant to humans and what is not, this work neutrally contextualizes man’s place in the biosphere. It offers a new mode of thinking and positioning of the ecological imperative, and will appeal to all those working with social and ecological systems.

Download or read book Cinema and Painting written by Angela Dalle Vacche and published by University of Texas Press. This book was released on 1996 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual image is the common denominator of cinema and painting, and indeed many filmmakers have used the imagery of paintings to shape or enrich the meaning of their films. In this discerning new approach to cinema studies, Angela Dalle Vacche discusses how the use of pictorial sources in film enables eight filmmakers to comment on the interplay between the arts, on the dialectic of word and image, on the relationship between artistic creativity and sexual difference, and on the tension between tradition and modernity. Specifically, Dalle Vacche explores Jean-Luc Godard's iconophobia (Pierrot Le Fou) and Andrei Tarkovsky's iconophilia (Andrei Rubleov), Kenji Mizoguchi's split allegiances between East and West (Five Women around Utamaro), Michelangelo Antonioni's melodramatic sensibility (Red Desert), Eric Rohmer's project to convey interiority through images (The Marquise of O), F. W. Murnau's debt to Romantic landscape painting (Nosferatu), Vincente Minnelli's affinities with American Abstract Expressionism (An American in Paris), and Alain Cavalier's use of still life and the close-up to explore the realms of mysticism and femininity (Thérèse). While addressing issues of influence and intentionality, Dalle Vacche concludes that intertextuality is central to an appreciation of the dialogical nature of the filmic medium, which, in appropriating or rejecting art history, defines itself in relation to national traditions and broadly shared visual cultures.
Download or read book Multivariate Image Processing written by Jocelyn Chanussot and published by Wiley-ISTE. This book was released on 2009-12-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multivariate imagery is now a very common tool in numerous applications, ranging from satellite remote sensing and astrophysics to biomedical imagery, monitoring of the environment or industrial inspection. Multivariate must be understood in th emost general way: color and multispectral imaging, but also multimodal, multisource or multitemporal imagery. In all the cases, the multivariate image corresponds to a set of standard grey level images. The availability of the additional diversity, be it spectral temporal and s.o., provides an invaluable source of information, enabling to consider a wide range of new applications. However, in order to address these applications, theoretical developments are required in terms of signal and image processing, or, more generally speaking, information processing. As a matter of fact, most of the standard algorithms designed for grey level images do not generalize easily to multidimensional spaces and some specific derivations are required. This book aims at presenting the most recent advances in signal and image processing for the analysis of multivariate data. It should be helpful for electrical engineers, PhD students and researcher working in the field of signal processing, but also for any engineer dealing with some specific application where multidimensional data are processed.
