Book excerpt: LE DEVELOPPEMENT ACTUEL DE LA NEUROBIOLOGIE PERMET D'ENVISAGER DES PERSPECTIVES NOUVELLES, ET EN MEME TEMPS DE COMPRENDRE LE FONCTIONNEMENT DU CORPS HUMAIN, PARTICULIEREMENT DU SYSTEME VISUEL. LES RESULTATS ACTUELS EXPLIQUENT COMMENT L'OEIL REAGIT A UN SIGNAL ET QUELS SONT LES DIFFERENTS TRAITEMENTS ET ANALYSES EFFECTUES AU NIVEAU DU CORTEX VISUEL. DANS LES METHODES CLASSIQUES DE TRAITEMENT D'IMAGES, LES PHENOMENES RETINO-CORTICAUX SONT SOUVENT NEGLIGES. LES SPECIALISTES DU TRAITEMENT NUMERIQUE DE L'IMAGE PREFERENT S'ORIENTER VERS DES MODELES MATHEMATIQUES TRES SOPHISTIQUES, ET IGNORENT COMPLETEMENT LES PHENOMENES NATURELS. DANS CETTE THESE, QUI COMPORTE SIX CHAPITRES, NOUS AVONS ESSAYE DE SOULIGNER L'INTERET DE LA PRISE EN COMPTE DES MECANISMES VISUELS POUR LE TRAITEMENT D'IMAGES BAS NIVEAU. EN NOUS APPUYANT SUR DES RESULTATS PSYCHOVISUELS ET NEUROBIOLOGIQUES, NOUS PROPOSONS DE NOUVELLES METHODES DE SEGMENTATION D'IMAGES, A SAVOIR SUR LE REHAUSSEMENT DU CONTRASTE, LE FILTRAGE PASSE BAS NON LINEAIRE, LA DETECTION DES CONTOURS, ET LA REQUANTIFICATION D'IMAGES. DE PLUS, NOUS AVONS INTRODUIT LE PARAMETRE TEMPS DONT NOUS AVONS MONTRE L'IMPORTANCE DANS LE TRAITEMENT D'IMAGES. CE PARAMETRE EST SOUVENT NEGLIGE DANS LES METHODES HABITUELLES. UNE ADAPTATION ADEQUATE DE CE FACTEUR PERMET D'EXTRAIRE L'INFORMATION PERTINENTE DE L'IMAGE ET REDUIT CONSIDERABLEMENT LE BRUIT DANS L'IMAGE. DE MEME LA NOTION DE CONTRASTE, LES FILTRES DE GABOR, LA LOI DE WEBER-FECHNER, LA LOI DE HOLLADAY, AINSI QUE LA TECHNIQUE DE DIFFUSION SONT DETAILLEES. CE TRAVAIL CONFIRME BIEN LES SOLUTIONS MISES EN OEUVRE PAR LA NATURE SONT A LA FOIS SIMPLES ET EFFICACES, ET QU'ELLES PEUVENT ETRE UNE SOURCE INEPUISABLE D'INSPIRATION POUR LES TRAITEURS D'IMAGES ET LES CONCEPTEURS DE SYSTEMES DE VISION ARTIFICIELLE EN GENERAL.

Download or read book An Introduction to Differential Manifolds written by Jacques Lafontaine and published by Springer. This book was released on 2015-07-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.

Available in PDF, EPUB and Kindle. Book excerpt: Color Atlas of Equine Pathology offers a practical guide to identifying equine diseases, presenting a single resource with more than 1000 images showing predominantly gross pathology. Organized by body systems, the book allows for picture matching during or after an equine necropsy. In this user-friendly atlas, each chapter takes a common format, presenting the disease process as well as congenital, degenerative, inflammatory, and neoplastic sequences, with text boxes offering quick reference to key information. The book begins with an introductory chapter summarizing the principles of the equine field necropsy, and subsequent organ-based chapters depict gross features of disease, focusing on macroscopic digital images supplemented by histology and immunohistochemistry when necessary. Some clinical information for correlation with pathology is included. Color Atlas of Equine Pathology is an essential resource for diagnostic veterinary pathologists and pathology residents, as well as for equine practitioners performing necropsies in the field.

Download or read book Playing with Form written by Alexander Alland and published by Columbia University Press. This book was released on 1983 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of the child's ability to draw is an inherently fascinating and complex subject. Many theories have been proposed to explain this development, but until now o on has undertaken a cross-cultural, controlled study of children in the act of drawing. "Playing with Form" is the first empirical study of children drawing in diverse cultures. Alexander Alland, Jr. spent eight months observing and filming children six cultures - Japan, Bali, Taiwan, Ponape, France, and the U.S. - as they drew. Attempting to determine the accuracy of current generalizations about the development of drawing skills as well as to understand the step-by step process of drawing, Alland amassed 240 drawings (100 of which are reproduced here) by children ranging from two to eight years old. The author uses this wealth of primary material to dispute much current thinking about children's drawing, particular theories about specific universal stages of development. While he does suggest some general rules which underlie the process of drawing, Alland argues that cultural differences reflect rules which are specific to the culture in which children' "play with form". An invaluable first step toward understanding the exact role culture plays in the development of style in children's drawing, "Playing with Form" will be of fundamental interest to anthropologists, developmental psychologists, art historians, and elementary school teachers. -- back cover
Download or read book What Is Art For written by Ellen Dissanayake and published by University of Washington Press. This book was released on 2015-09-01 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every human society displays some form of behavior that can be called “art,” and in most societies other than our own the arts play an integral part in social life. Those who wish to understand art in its broadest sense, as a universal human endowment, need to go beyond modern Western elitist notions that disregard other cultures and ignore the human species’ four-million-year evolutionary history. This book offers a new and unprecedentedly comprehensive theory of the evolutionary significance of art. Art, meaning not only visual art, but music, poetic language, dance, and performance, is for the first time regarded from a biobehavioral or ethical viewpoint. It is shown to be a biological necessity in human existence and fundamental characteristic of the human species. In this provocative study, Ellen Dissanayake examines art along with play and ritual as human behaviors that “make special,” and proposes that making special is an inherited tendency as intrinsic to the human species as speech and toolmaking. She claims that the arts evolved as means of making socially important activities memorable and pleasurable, and thus have been essential to human survival. Avoiding simplism and reductionism, this original synthetic approach permits a fresh look at old questions about the origins, nature, purpose, and value of art. It crosses disciplinary boundaries and integrates a number of divers fields: human ethology; evolutionary biology; the psychology and philosophy of art; physical and cultural anthropology; “primitive” and prehistoric art; Western cultural history; and children’s art. The final chapter, “From Tradition to Aestheticism,” explores some of the ways in which modern Western society has diverged from other societies--particularly the type of society in which human beings evolved--and considers the effects of the aberrance on our art and our attitudes toward art. This book is addressed to readers who have a concerned interest in the arts or in human nature and the state of modern society.

Download or read book Stress and Coping in Infancy and Childhood written by Tiffany M. Field and published by Psychology Press. This book was released on 2013-02-01 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fourth volume based on the annual University of Miami symposia on stress and coping, this new addition to the series is the first to focus on developmental and clinical stressors during infancy and childhood. While developmental stressors such as early separation and stranger anxiety, novelty stress, and fear-evoked personal distress, arise during normal development, clinical stressors result from certain conditions that are relatively common in infancy and early childhood such as premature birth and respiratory disease. Various therapies are discussed -- for example, relaxation and massage -- that can alleviate the stress associated with psychiatric conditions in childhood and adolescence, including depression and adjustment disorder. The result is an integration of diverse research and theory on the psychophysiological, developmental, and psychosocial aspects of stress and coping in animals and humans by some of the leading researchers in the field.

Download or read book Journey Through the Ice Age written by Paul G. Bahn and published by Univ of California Press. This book was released on 1997-01-01 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the oldest art in the world is the subject of this riveting and beautiful book. Paul Bahn and Jean Vertut explore carved objects and wall art discoveries from the Ice Age, covering the period from 300,000 B.P. to 10,000 B.P., and their collaboration marks a signal event for archaeologists and lay readers alike. Utilizing the most modern analytical techniques in archaeology, Bahn presents new accounts of Russian caves only recently opened to foreign specialists; the latest discoveries from China and Brazil; European cave finds at Cosquer, Chauvet, and Covaciella; and the recently discovered sites in Australia. He also studies sites in Africa, India, and the Far East. Included are the only photographic images of many caves that are now closed to protect their fragile environments. A separate chapter in the book examines art fakes and forgeries and relates how such deceptions have been exposed. The beliefs and preoccupations of Paleolithic peoples resonate throughout this book: the importance of the hunt and the magic and shamanism surrounding it, the recording of the seasons, the rituals of sex and fertility, the cosmology and associated myths. Yet enigmas and mysteries emerge as well, particularly as new analytical techniques raise new questions and cast doubt on our earlier suppositions. A comprehensive, up-to-date analysis of all that has been discovered about Ice Age art, Bahn and Vertut's book offers a visually rich link with the past.
