Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL DECRIT LA RELAXATION SELECTIONNISTE, UNE METHODE NOUVELLE DE SEGMENTATION D'IMAGES EN MODE NON-SUPERVISE. CETTE METHODE CONSISTE A FAIRE EVOLUER DES POPULATIONS D'UNITES CAPABLES DE RECONNAITRE DES CARACTERISTIQUES LOCALES SUR L'IMAGE. AU COURS DE CETTE EVOLUTION, INDUITE PAR UN ALGORITHME GENETIQUE, LES POPULATIONS ENVAHISSENT PROGRESSIVEMENT ET DE MANIERE SPECIFIQUE LES REGIONS A SEGMENTER. DANS UNE PREMIERE PARTIE, LA METHODE EST APPLIQUEE A LA SEGMENTATION PAR L'INTENSITE LUMINEUSE. GRACE A UN MODELE DU COMPORTEMENT ASYMPTOTIQUE DES POPULATIONS D'UNITES, ON PROPOSE UNE CONDITION SUR L'AJUSTEMENT OPTIMAL DES PARAMETRES DE L'ALGORITHME GENETIQUE. LES PREDICTIONS OBTENUES SONT VALIDEES SUR DES DONNEES SYNTHETIQUES. ON DEMONTRE AINSI L'EXISTENCE D'UNE QUANTITE OPTIMALE DE MUTATION PROPORTIONNELLE A LA VARIANCE DES NIVEAUX DE GRIS DES REGIONS. ON MONTRE EGALEMENT QUE LA RECOMBINAISON N'A PAS D'INFLUENCE SIGNIFICATIVE SUR LA QUALITE DE LA SEGMENTATION FINALE, MAIS QU'ELLE DETERMINE LA QUALITE DES SEGMENTATIONS INTERMEDIAIRES. LA METHODE EST ENSUITE TESTEE SUR DIVERSES SCENES REELLES. DANS UNE SECONDE PARTIE, LA METHODE EST APPLIQUEE A LA SEGMENTATION DES TEXTURES. LES TEXTURES SONT MODELISEES PAR DES CHAMPS DE GIBBS/MARKOV. UNE APPROXIMATION DE LA FONCTION DE PARTITION EST PROPOSEE POUR CONTOURNER L'IMPOSSIBILITE D'EN CALCULER LA VALEUR EXACTE DANS LE MODELE RETENU (MODELE D'ISING GENERALISE). LA TECHNIQUE EST TESTEE SUR DES MONTAGES DE TEXTURES SYNTHETIQUES, PUIS SUR DES MONTAGES DE TEXTURES NATURELLES. DANS CHACUNE DES DEUX PARTIES, LA COMPARAISON DES RESULTATS OBTENUS AVEC CEUX FOURNIS PAR DES METHODES ALTERNATIVES SOULIGNE L'IMPORTANCE DES PROPRIETES ADAPTATIVES DE LA RELAXATION SELECTIONNISTE DANS DES SITUATIONS OU LA VARIABILITE D'UNE IMAGE, D'UNE REGION OU ENCORE D'UN SITE A L'AUTRE EST FORTE ET OU AUCUNE INFORMATION A PRIORI N'EST DISPONIBLE.
Download or read book Biomedical Images and Computers written by J. Sklansky and published by Springer. This book was released on 2014-03-12 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technology of automatic pattern recognition and digital image processing, after over two decades of basic research, is now appearing in important applications in biology and medicine as weIl as industrial, military and aerospace systems. In response to a suggestion from Mr. Norman Caplan, ·the Program Director for Automation, Bioengineering and Sensing at the United States National Science Foundation, the authors of this book organized the first Uni ted States-France Seminar on Biomedical Image Processing. The seminar met at the Hotel Beau Site, St. Pierre de Chartreuse, France on May 27-31, 1980. This book contains most of the papers presented at this seminar, as weIl as two papers (by Bisconte et al. and by Ploem ~ al.) discussed at the seminar but not appearing on the program. We view the subject matter of this seminar as a confluence amon~ three broad scientific and engineering disciplines: 1) biology and medicine, 2) imaging and optics, and 3) computer science and computer engineering. The seminar had three objectives: 1) to discuss the state of the art of biomedical image processing with emphasis on four themes: microscopic image analysis, radiological image analysis, tomography, and image processing technology; 2) to place values on directions for future research so as to give guidance to agencies supporting such research; and 3) to explore and encourage various areas of cooperative research between French and Uni ted States scientists within the field of Biomedical Image Processing.

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 Network Coding written by Khaldoun Al Agha and published by John Wiley & Sons. This book was released on 2012-12-27 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Network coding, a relatively new area of research, has evolved from the theoretical level to become a tool used to optimize the performance of communication networks – wired, cellular, ad hoc, etc. The idea consists of mixing “packets” of data together when routing them from source to destination. Since network coding increases the network performance, it becomes a tool to enhance the existing protocols and algorithms in a network or for applications such as peer-to-peer and TCP. This book delivers an understanding of network coding and provides a set of studies showing the improvements in security, capacity and performance of fixed and mobile networks. This is increasingly topical as industry is increasingly becoming more reliant upon and applying network coding in multiple applications. Many cases where network coding is used in routing, physical layer, security, flooding, error correction, optimization and relaying are given – all of which are key areas of interest. Network Coding is the ideal resource for university students studying coding, and researchers and practitioners in sectors of all industries where digital communication and its application needs to be correctly understood and implemented.

Download or read book Water Flow and Solute Transport in Soils written by David Russo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: A year has passed since Eshel Bresler, my good friend and colleague, and a member of the editorial board of the Advanced Series in Agricultural Sciences, died suddenly while on a visit to the Chinese Academy of Sciences in Beijing. We had worked together for almost 30 years at the Institute of Soils and Water, ARO, The Volcani Center at Bet Dagan. At the very beginning of our scientific careers we cooperated directly and as a result one of our first publications was coauthored (Soil Sci. 101:205-209, 1966). Thereafter, our specific research interests diver sified, but we continued to work together, with similar approaches to research, and to strive towards the development of Israel soil science and its integration into general worldwide scientific progress. I don't need to emphasize Eshel's contribution to the understan ding of the processes governing water flow and solute transport pro cesses in soils and unsaturated zones. The contributions to this Volume by such a body of outstanding scientists shows the apprecia tion of the international scientific community to his research achievements.
Download or read book Statistical Methods for Estimating Petroleum Resources written by P.J. Lee and published by Oxford University Press. This book was released on 2008-05-07 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes procedures for determining the total hydrocarbon (petroleum) resource or resource potential in a region. Statistical concepts and methods employed in petroleum resource assessment are the subject of the manuscript, extensively illustrated by numerous real case studies. Prof. Lee's computer-aided Petroleum Information Management and Resource Evaluation System (PETRIMES) methodology has been adopted by governments around the world and by major multinational oil companies to perform resource assessment and to predict future oil and gas production. Though this methodology is so widely used, there is no "user's guide" to it, and this book will be the definitive resource for PETRIMES users.
