Book excerpt: LES TRAVAUX PRESENTES DANS CETTE THESE SONT CONSACRES AU DEVELOPPEMENT D'UN OUTIL MORPHOLOGIQUE DE TRAITEMENT D'IMAGES ET A SON APPLICATION EN SEGMENTATION D'IMAGES TEXTURELLES. LA DECOMPOSITION MORPHOLOGIQUE MULTI-TAILLES (DMM) DEVELOPPEE SE FONDE SUR LA MORPHOLOGIE MATHEMATIQUE MULTI-NIVEAUX. ELLE PEUT ITERATIVEMENT DECOMPOSER UNE IMAGE EN UN ENSEMBLE D'IMAGES COMPOSANTES EN UTILISANT UN GROUPE D'ELEMENTS STRUCTURANTS. LE CONTENU DE LA DECOMPOSITION DEPEND DE LA TAILLE ET DE LA VARIATION DU NIVEAU DE GRIS DES OBJETS PRESENTS DANS L'IMAGE. CETTE DECOMPOSITION EST IDEMPOTENTE, SANS PERTE D'INFORMATION, ET RAPIDE EN TEMPS CALCUL. DE PLUS L'IMAGE ORIGINALE PEUT ETRE RECONSTITUEE PAR LA SOMME DE TOUTES LES IMAGES COMPOSANTES. LES TESTS EN CLASSIFICATION DE TEXTURES DEMONTRENT QUE LES ATTRIBUTS TEXTURELS EXTRAITS DES IMAGES COMPOSANTES SONT EFFICACES POUR CLASSIFIER LES TEXTURES TANT STRUCTURELLES QU'ALEATOIRES. CEPENDANT, IL EXISTE ENCORE UN AUTRE PROBLEME DELICAT EN SEGMENTATION D'IMAGES TEXTURELLES PAR CLASSIFICATION: LA DETERMINATION DES FRONTIERES ENTRE DIFFERENTES TEXTURES CONTENUES DANS UNE IMAGE. DES TECHNIQUES ADAPTATIVES SONT DONC PROPOSEES POUR RESOUDRE CE PROBLEME. TOUT D'ABORD, LA TAILLE ADEQUATE DE LA FENETRE DANS LAQUELLE LES ATTRIBUTS SONT EXTRAITS EST AUTOMATIQUEMENT DETERMINEE A PARTIR DES TEXTURES CONTENUES DANS L'IMAGE A SEGMENTER, AU MOYEN DE L'ESTIMATION DU RISQUE BAYESIEN. ENSUITE, DEUX METHODES DE TRAITEMENT DES FRONTIERES SONT PROPOSEES POUR REDUIRE EFFICACEMENT LES ERREURS DE SEGMENTATION AUTOUR DES FRONTIERES DE DIFFERENTES TEXTURES DANS L'IMAGE. ENFIN, L'ETUDE DES PROPRIETES STATISTIQUES DE LA MORPHOLOGIE MATHEMATIQUE NOUS PERMET DE MIEUX CONNAITRE SON MECANISME ET SES EFFETS SUR DIFFERENTS TYPES DE SIGNAUX DANS LE CAS BRUITE. CECI CONDUIT EGALEMENT A LA GENERALISATION DE LA DECOMPOSITION PAR LE FILTRE D'ORDRE AFIN DE BIEN ADAPTER L'ALGORITHME AUX TEXTURES BRUITEES

ON PROPOSE ICI EN SUPPRESSION DU BRUIT D'IMAGES LES FILTRES MORPHOLOGIQUES COMPOSITES SE FONDANT SUR LES COMBINAISONS DE L'OUVERTURE, LA FERMETURE ET LA TRANSFORMATION IDENTIQUE. LES COMPARAISONS QUANTITATIVES DE L'EFFICACITE A LA FOIS EN SUPPRESSION DU BRUIT ET EN CONSERVATION DE DETAILS D'IMAGES POUR DES FILTRES MORPHOLOGIQUES ET D'AUTRES FILTRES NON-LINEAIRES SONT FAITES DANS LE CADRE D'UN SCHEMA DE CARACTERISATION DE L'ACTIVITE SPATIALE LOCALE D'IMAGES. LA CONCEPTION DU FILTRE MORPHOLOGIQUE PAR UN ALGORITHME GENETIQUE ADAPTATIF DESTINE A UNE SUPPRESSION DU BRUIT OPTIMALE CHOISISSANT A LA FOIS LE TYPE DE FILTRAGE ET L'ELEMENT STRUCTURANT EST PROPOSEE. DE NOUVEAUX ATTRIBUTS MORPHOLOGIQUES BASES SUR LES RESIDUS DE FILTRAGE MORPHOLOGIQUE PAR RECONSTRUCTION SONT DEVELOPPES. L'AVANTAGE DE CES ATTRIBUTS EST LIE A LEUR ROBUSTESSE AUX DIFFERENTS TYPE DE BRUIT. UN ALGORITHME PERMETTANT LE CHOIX D'UN SOUS-ENSEMBLE DE CES ATTRIBUTS LE PLUS PERFORMANT POUR LA MEILLEURE CLASSIFICATION DE TEXTURES EST CONCU. UNE APPLICATION DE CES ATTRIBUTS EST ILLUSTREE EN CLASSIFICATION D'IMAGES SPOT PAR LA SEGMENTATION DE TEXTURES. L'INTRODUCTION DE LA RECONSTRUCTION MORPHOLOGIQUE DANS L'ALGORITHME DE DECOMPOSITION MORPHOLOGIQUE MULTIRESOLUTION NOUS PERMET D'OBTENIR UN SCHEMA DE DECOMPOSITION DES STRUCTURES SELON LA TAILLE. CETTE DECOMPOSITION EST IDEMPOTENTE ET SANS PERTE D'INFORMATION. DEUX APPLICATIONS UTILISANT PRINCIPALEMENT CETTE METHODE DE DECOMPOSITION EN SEGMENTATION DE STRUCTURES DES IMAGES MEDICALES SONT DECRITES. LA PREMIERE CONCERNE LA SEGMENTATION DE LESIONS DU POUMON, ET LA SECONDE ETUDE CONCERNE LA SEGMENTATION DES DIFFERENTES STRUCTURES D'UNE REGION DE TUMEURS DU CERVEAU. D'AUTRES OUTILS MORPHOLOGIQUES TELS QUE LE FILTRAGE, LE GRADIENT, LA DILATATION ET L'AMINCISSEMENT SONT EGALEMENT EMPLOYES DANS CES APPLICATIONS.

This book was released on 2005-07-28 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical Morphology is a speciality in Image Processing and Analysis, which considers images as geometrical objects, to be analyzed through their interactions with other geometrical objects. It relies on several branches of mathematics, such as discrete geometry, topology, lattice theory, partial differential equations, integral geometry and geometrical probability. It has produced fast and efficient algorithms for computer analysis of images, and has found applications in bio-medical imaging, materials science, geoscience, remote sensing, quality control, document processing and data analysis. This book contains the 43 papers presented at the 7th International Symposium on Mathematical Morphology, held in Paris on April 18-20, 2005. It gives a lively state of the art of current research topics in this field. It also marks a milestone, the 40 years of uninterrupted development of this ever-expanding domain.

Download or read book Microsound written by Curtis Roads and published by National Geographic Books. This book was released on 2004-08-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Below the level of the musical note lies the realm of microsound, of sound particles lasting less than one-tenth of a second. Recent technological advances allow us to probe and manipulate these pinpoints of sound, dissolving the traditional building blocks of music—notes and their intervals—into a more fluid and supple medium. The sensations of point, pulse (series of points), line (tone), and surface (texture) emerge as particle density increases. Sounds coalesce, evaporate, and mutate into other sounds. Composers have used theories of microsound in computer music since the 1950s. Distinguished practitioners include Karlheinz Stockhausen and Iannis Xenakis. Today, with the increased interest in computer and electronic music, many young composers and software synthesis developers are exploring its advantages. Covering all aspects of composition with sound particles, Microsound offers composition theory, historical accounts, technical overviews, acoustical experiments, descriptions of musical works, and aesthetic reflections.

Download or read book Morphological Image Analysis written by Pierre Soille and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is self-contained in the sense that it is accessible to engineers, scientists, and practitioners having no prior experience with morphology. In addition, most necessary background notions about digital image processing are covered. The emphasis being put on the techniques useful for solving practical problems rather than the theory underlying mathematical morphology, no special knowledge about set theory and topology is required. Nevertheless, the book goes well beyond an introduction to mathematical morphology. Indeed, starting from the fundamental transformations, more elaborate methods which have proven their practical usefulness are explained. This is achieved through a step by step process pursued until the most recent advances.

Download or read book Image Textures and Gibbs Random Fields written by Georgiĭ Lʹvovich Gimelʹfarb and published by Springer Science & Business Media. This book was released on 1999 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text presents techniques for describing image textures. Contrary to the usual practice of embedding the images to known modelling frameworks borrowed from statistical physics or other domains, this book deduces the Gibbs models from basic image features and tailors the modelling framework to the images. This approach results in more general Gibbs models than can be either Markovian or non-Markovian and possess arbitrary interaction structures and strengths. The book presents computationally feasible algorithms for parameter estimation and image simulation and demonstrates their abilities and limitations by numerous experimental results.
