Available in PDF, EPUB and Kindle. Book excerpt: L'utilisation de la couleur dans les étapes de segmentation va aboutir, grâce à l'apport complémentaire d'informations (données tridimensionnelles), à de meilleurs résultats qu'en utilisant une représentation monochrome. La traduction de cette information dans un espace Teinte-Luminance-Saturation, très proche de la perception humaine des couleurs, permet une interprétation aisée, une certaine indépendance et une complémentarité entre les informations. Ceci va faciliter l'intégration des caractéristiques spécifiques des images couleurs dans le processus de segmentation. Cependant, l'un des soucis de la mise au point des méthodes de traitement couleur sera de ne pas payer le gain de performance par un accroissement important des temps de traitements. Une stratégie peut alors consister à chercher à fusionner les informations apportées par les trois composantes afin de définir une information unique traduisant soit un critère d'homogénéité dans le cas de la segmentation en régions, soit un critère de discontinuité dans le cas de la détection de contours. Cette fusion des données peut être envisagée par une approche classique, en effectuant une somme pondérée des informations, ou bien en employant des techniques de fusion plus élaborées reposant sur des représentations symboliques associées à la théorie des sous-ensembles flous.

Download or read book Space Structure and Randomness written by Michel Bilodeau and published by Springer Science & Business Media. This book was released on 2007-12-23 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space, structure, and randomness: these are the three key concepts underlying Georges Matheron’s scientific work. He first encountered them at the beginning of his career when working as a mining engineer, and then they resurfaced in fields ranging from meteorology to microscopy. What could these radically different types of applications possibly have in common? First, in each one only a single realisation of the phenomenon is available for study, but its features repeat themselves in space; second, the sampling pattern is rarely regular, and finally there are problems of change of scale. This volume is divided in three sections on random sets, geostatistics and mathematical morphology. They reflect his professional interests and his search for underlying unity. Some readers may be surprised to find theoretical chapters mixed with applied ones. We have done this deliberately. GM always considered that the distinction between the theory and practice was purely academic. When GM tackled practical problems, he used his skill as a physicist to extract the salient features and to select variables which could be measured meaningfully and whose values could be estimated from the available data. Then he used his outstanding ability as a mathematician to solve the problems neatly and efficiently. It was his capacity to combine a physicist’s intuition with a mathematician’s analytical skills that allowed him to produce new and innovative solutions to difficult problems. The book should appeal to graduate students and researchers working in mathematics, probability, statistics, physics, spatial data analysis, and image analysis. In addition it will be of interest to those who enjoy discovering links between scientific disciplines that seem unrelated at first glance. In writing the book the contributors have tried to put GM’s ideas into perspective. During his working life, GM was a genuinely creative scientist. He developed innovative concepts whose usefulness goes far beyond the confines of the discipline for which they were originally designed. This is why his work remains as pertinent today as it was when it was first written.

Download or read book 3D Video written by Laurent Lucas and published by John Wiley & Sons. This book was released on 2013-12-04 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: While 3D vision has existed for many years, the use of 3D cameras and video-based modeling by the film industry has induced an explosion of interest for 3D acquisition technology, 3D content and 3D displays. As such, 3D video has become one of the new technology trends of this century. The chapters in this book cover a large spectrum of areas connected to 3D video, which are presented both theoretically and technologically, while taking into account both physiological and perceptual aspects. Stepping away from traditional 3D vision, the authors, all currently involved in these areas, provide the necessary elements for understanding the underlying computer-based science of these technologies. They consider applications and perspectives previously unexplored due to technological limitations. This book guides the reader through the production process of 3D videos; from acquisition, through data treatment and representation, to 3D diffusion. Several types of camera systems are considered (multiscopic or multiview) which lead to different acquisition, modeling and storage-rendering solutions. The application of these systems is also discussed to illustrate varying performance benefits, making this book suitable for students, academics, and also those involved in the film industry.

Available in PDF, EPUB and Kindle. Book excerpt: Les médias 3D relief, leur capture, leur retransmission en relief, possiblement en direct, sont aujourd’hui disponibles et portent l’évolution attendue pour la télévision et l’Internet. Ces technologies (« télévision 3D », « free viewpoint TV » ou « Vidéo 3D »), impactent toute la chaîne audiovisuelle : · les techniques d'acquisition relief sont plus variées · les scènes sont représentées par des structures numériques plus ou moins informatives : vidéos multi-vues sans/avec profondeur, modèles 3D · la reconstruction extrait lesdites représentations des vidéos multi-vues, · leur compression facilite la diffusion des médias, · l'affichage (auto-)stéréoscopique, avec/sans adaptation/enrichissement et/ou synthèse de vues intermédiaires, permet l’expérience visuelle immersive ciblée. La vidéo 3D recouvre donc de multiples facettes. Visant à donner aux étudiants une vision d’ensemble du sujet et aux chercheurs un texte de référence actuel aussi complet que possible, cet ouvrage en présente les principaux développements relevant de domaines variés : mathématiques appliquées, vision par ordinateur, informatique graphique, réalité virtuelle, psychophysique et physiologie de la vision humaine...

This book was released on 2012-04-16 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage collectif recense les dernières avancées dans le domaine de l'analyse automatique des images numériques couleur. Destiné aux chercheurs, ingénieurs R&D et étudiants en Master ou Doctorat, il constitue un état de l'art critique et le plus exhaustif possible sur les problématiques scientifiques soulevées par les différentes étapes constituant une chaîne de traitement des images couleur. Le filtrage et la segmentation des images fixes sont abordés par des techniques récentes telles que les outils morphologiques couleur, les équations aux dérivées partielles, l'algèbre quaternionique ou l'analyse de graphes. La caractérisation des textures couleur est traitée par la prédiction linéaire ou des descripteurs statistiques. La reconnaissance d'objets fixes ou en mouvement dans des vidéos couleur nécessite d'utiliser des attributs invariants aux conditions d'éclairage. Une attention particulière a été apportée aux espaces couleur, et notamment ceux séparant la luminance de la chrominance.

This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: L'étude de ce présent rapport de stage s'inscrit dans les programmes de recherche en traitement d'images du laboratoire L.C.I.A. à l'Université de Mont-Saint-Aignan. Elle traite des différentes méthodes de segmentation des images couleurs par la technique de l'accroissement de régions. La segmentation a pour but principal de fragmenter une image en zones homogènes dans le souci ultérieur d'une analyse de scène. Trois axes de recherche sont envisagés dans ce rapport : - Etude dans un premier temps des différents moyens de représentation de la couleur : nous présentons dans chacun des cas les avantages et les inconvénients de ces plans image pour notre application. - Description détaillée des différents algorithmes par accroissement de régions et leur implémentation en langage C. - Nous définissons enfin les critères de segmentation pour le regroupement des pixels. Il est bien évident que le choix de ces critères (s'appuyant sur des valeurs statistiques de répartition spatiale des pixels dans l'image) est différent selon l'objectif que l'on se fixe pour la segmentation. Dans ce cas nous expliquons l'intérêt de ces critères.
