Available in PDF, EPUB and Kindle. Book excerpt: La segmentation d'images permet le partitionnement d'une image en regions, ou chaque region est constituee d'un ensemble de composantes connexes, son but est l'extraction des informations pertinentes des objets afin de permettre leurs interpretations. Elle reste un probleme pose, jusqu'en ce moment il n'existe pas une methode automatique permettant la segmentation d'une image de maniere efficace et cela malgre la multiplicite d'approches. Dans ce travail, nous proposons un systeme de segmentation d'images implemente dans un environnement multi-agents baptisee SIMA. Ce systeme procede a la segmentation d'images en deux etapes: une etape de pre-segmentation qui consiste a faire une classification FCM suivi d'un etiquetage de l'image. Une autre etape de reajustement et comprenant deux phases: la premiere consiste a eliminer les fausses regions (PEFR) et la deuxieme consiste a reajuster les contours en reaffectant leurs pixels aux regions de l'image (PRPC).

This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Etant donné son importance et sa difficulté, la segmentation d'images est actuellement un des domaines les plus étudiés en analyse d'images. Un grand nombre d'opérateurs de segmentation ont été développés et sont décrits dans la littérature. Malgré la complexité de certains de ces opérateurs, des études comparatives récentes nous montrent qu'il n'y a aucune technique qui se détache pour prétendre le titre de "la meilleure méthode". Il se pose alors un problème de choix de l'opérateur à appliquer en fonction d'une variété d'informations que l'on va regrouper sous le nom de contexte (nature et caractéristiques de l'image, primitives à extraire, contraintes d'exploitation). Dans cette thèse, on propose une méthode générale pour la détection de contours vue comme un problème d'adaptation des opérateurs. L'adaptation est définie comme un problème de sélection d'un enchaînement d'opérateurs (prétraitement, détection de contours, post-traitement) approprié ainsi que le réglage des paramètres de ces opérateurs, en fonction du contexte de la segmentation. L'estimation des caractéristiques de l'image (comme le bruit, la texture, le contraste, le modèle des contours) et l'évaluation de la qualité du résultat jouent un rôle important dans le cadre de cette méthode. Plusieurs approches algorithmiques sont proposées, combinant différents types et techniques d'adaptation : adaptation a priori/a posteriori, adaptation globale/locale, adaptation heuristique/par optimisation. Ces différentes approches sont illustrées et validées d'une façon expérimentale sur des images artificielles et réelles. Une implantation multi-agents de la méthode est également proposée, en utilisant COALA, une plate-forme de développement des systèmes multi-agents. Deux architectures multi-agents sont présentées, pour implanter deux approches différentes de la méthode : une approche heuristique et une approche par optimisation

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.

Download or read book Metaheuristic Algorithms for Image Segmentation Theory and Applications written by Diego Oliva and published by Springer. This book was released on 2019-03-02 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a study of the most important methods of image segmentation and how they are extended and improved using metaheuristic algorithms. The segmentation approaches selected have been extensively applied to the task of segmentation (especially in thresholding), and have also been implemented using various metaheuristics and hybridization techniques leading to a broader understanding of how image segmentation problems can be solved from an optimization perspective. The field of image processing is constantly changing due to the extensive integration of cameras in devices; for example, smart phones and cars now have embedded cameras. The images have to be accurately analyzed, and crucial pre-processing steps, like image segmentation, and artificial intelligence, including metaheuristics, are applied in the automatic analysis of digital images. Metaheuristic algorithms have also been used in various fields of science and technology as the demand for new methods designed to solve complex optimization problems increases. This didactic book is primarily intended for undergraduate and postgraduate students of science, engineering, and computational mathematics. It is also suitable for courses such as artificial intelligence, advanced image processing, and computational intelligence. The material is also useful for researches in the fields of evolutionary computation, artificial intelligence, and image processing.

Download or read book Variational and Level Set Methods in Image Segmentation written by Amar Mitiche and published by Springer Science & Business Media. This book was released on 2010-10-22 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Image segmentation consists of dividing an image domain into disjoint regions according to a characterization of the image within or in-between the regions. Therefore, segmenting an image is to divide its domain into relevant components. The efficient solution of the key problems in image segmentation promises to enable a rich array of useful applications. The current major application areas include robotics, medical image analysis, remote sensing, scene understanding, and image database retrieval. The subject of this book is image segmentation by variational methods with a focus on formulations which use closed regular plane curves to define the segmentation regions and on a level set implementation of the corresponding active curve evolution algorithms. Each method is developed from an objective functional which embeds constraints on both the image domain partition of the segmentation and the image data within or in-between the partition regions. The necessary conditions to optimize the objective functional are then derived and solved numerically. The book covers, within the active curve and level set formalism, the basic two-region segmentation methods, multiregion extensions, region merging, image modeling, and motion based segmentation. To treat various important classes of images, modeling investigates several parametric distributions such as the Gaussian, Gamma, Weibull, and Wishart. It also investigates non-parametric models. In motion segmentation, both optical flow and the movement of real three-dimensional objects are studied.
