This book was released on 2001 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de cette thèse est la quantification des phases de clinker de ciment par analyse d'images couleur issues d'un microscope optique. La segmentation des cristaux a été abordée par une double démarche adaptée aux contraintes industrielles : La première porte sur une méthode originale de calcul du gradient couleur dans le cas des images acquises avec une camera couleur standard mono-CCD. Ces images multi-spectrales ont la particularité de présenter une résolution réduite des composantes couleur par rapport à celle de la luminosité. L'adaptation d'une approche multi-échelle et une pondération des composantes sont intégrée dans un nouvel opérateur de gradient couleur multi-échelle (GCM). Les études comparatives avec des techniques classiques, effectuées dans le cadre de la détection des contours, montrent la contribution du GCM. Le deuxième modèle original concerne la segmentation d'images par un contour déformable de type "ballon". Notre modèle stabilise la déformation par normalisation de la longueur du contour actif avant chaque itération. Ceci permet des grandes déformations du contour sans requérir le ré-échantillonnage de la courbe, étape nécessaire dans l’approche classique. L’algorithme est plus rapide et plus robuste et autorise un contour initial loin du contour final.Le logiciel développé en partenariat avec la société Lafarge Ciments intègre ces différentes techniques de traitement d'image couleur : Pré-traitement des images, segmentation par approche contour effectuée à l'aide du GCM des images microscopiques couleur, une fermeture des contours. Les régions homogènes ainsi segmentées, sont ensuite classifiées grâce à des paramètres de texture et de couleur. Le système fourni une quantification des trois phases principales du clinker et une analyse statistique des dimensions des cristaux. Il remplace une mesure manuelle longue et fastidieuse et permet d’augmenter la qualité de la fabrication par des mesures plus fréquentes en sortie du four à ciment.

Available in PDF, EPUB and Kindle. Book excerpt: Qu'est-ce que la segmentation d'image Dans le traitement d'images numériques et la vision par ordinateur, la segmentation d'image est le processus de partitionnement d'une image numérique en plusieurs segments d'image, également appelés régions d'image ou objets images. Le but de la segmentation est de simplifier et/ou de modifier la représentation d'une image en quelque chose de plus significatif et plus facile à analyser. La segmentation d'images est généralement utilisée pour localiser des objets et des limites dans les images. Plus précisément, la segmentation d'image est le processus d'attribution d'une étiquette à chaque pixel d'une image de telle sorte que les pixels portant la même étiquette partagent certaines caractéristiques.

Book Synopsis Modèles de contours actifs pour la segmentation d'images et de vidéos by : Muriel Gastaud
Download or read book Modèles de contours actifs pour la segmentation d'images et de vidéos written by Muriel Gastaud and published by . This book was released on 2005 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: La segmentation en objets d’une image consiste à extraire une ou des régions d’intérêt de l’image, suivant un critère défini. Nous segmentons l’image par un algorithme de contours actifs, dans le cadre d’une approche variationnelle. Partant, d’un contour initial quelconque, le contour actif évolue vers la région d’intérêt, dirigé par une équation aux dérivées partielles. L’équation d’évolution du contour actif est déduite de la dérivation du critère définissant la région. Au vu de la dépendance du critère à la région considérée, la dérivation du critère par rapport à la région n’est pas aisée. Nous utilisons des outils de dérivation empruntés à l’optimisation de domaine : les gradients de forme. La contribution de cette thèse réside dans l’élaboration et l’étude de différents descripteurs de régions. Pour chaque critère, nous calculons la dérivée du critère à l’aide des gradients de forme et en déduisons l’équation d’évolution du contour actif. Le premier descripteur définit un a priori géométrique sans contrainte paramétrique : il minimise la distance du contour actif à un contour de référence. Nous l’avons appliqué à la déformation de courbe (shape warping), la segmentation et le suivi de cible (tracking). Le deuxième descripteur définit conjointement une région et son mouvement sur plusieurs images consécutives. Le mouvement de la région est représenté par un modèle de mouvement. Nous avons appliqué ce critère à l’estimation et la segmentation conjointe du mouvement et au suivi d’objets en mouvement.

Book Synopsis Local Approximation Techniques in Signal and Image Processing by : Vladimir I︠A︡kovlevich Katkovnik
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.

Book excerpt: Repackaged with a new afterword, this "valuable and entertaining" (New York Times Book Review) book explores how scientists are adapting nature's best ideas to solve tough 21st century problems. Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes readers into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; harness energy by examining how a leaf converts sunlight into fuel in trillionths of a second; and many more examples. Composed of stories of vision and invention, personalities and pipe dreams, Biomimicry is must reading for anyone interested in the shape of our future.

Book Synopsis Nonsmooth Optimization by : Claude Lemarechal
Download or read book Nonsmooth Optimization written by Claude Lemarechal and published by Elsevier. This book was released on 2014-05-19 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonsmooth Optimization contains the proceedings of a workshop on non-smooth optimization (NSO) held from March 28 to April 8,1977 in Austria under the auspices of the International Institute for Applied Systems Analysis. The papers explore the techniques and theory of NSO and cover topics ranging from systems of inequalities to smooth approximation of non-smooth functions, as well as quadratic programming and line searches. Comprised of nine chapters, this volume begins with a survey of Soviet research on subgradient optimization carried out since 1962, followed by a discussion on rates of convergence in subgradient optimization. The reader is then introduced to the method of subgradient optimization in an abstract setting and the minimal hypotheses required to ensure convergence; NSO and nonlinear programming; and bundle methods in NSO. A feasible descent algorithm for linearly constrained least squares problems is described. The book also considers sufficient minimization of piecewise-linear univariate functions before concluding with a description of the method of parametric decomposition in mathematical programming. This monograph will be of interest to mathematicians and mathematics students.

This book was released on 2001-11-30 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in computer applications has led to a new attitude to applied logic in which researchers tailor a logic in the same way they define a computer language. In response to this attitude, this text for undergraduate and graduate students discusses major algorithmic methodologies, and tableaux and resolution methods. The authors focus on first-order logic, the use of proof theory, and the computer application of automated searches for proofs of mathematical propositions.
