This book was released on 1992 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE THESE EST CONSACREE A DEUX CATEGORIES DE METHODES DE LA SEGMENTATION D'IMAGES: LA SEGMENTATION STATISTIQUE NON SUPERVISEE ET LA DETECTION DE CONTOURS PAR FILTRAGE. LES CONTRIBUTIONS DE CE TRAVAIL REPOSENT SUR LES ETUDES DES DEUX FAMILLES DE METHODES EN SOI ET SUR LEUR MISE EN PARALLELE. DANS LA PREMIERE PARTIE, NOUS ABORDONS LA SEGMENTATION BAYESIENNE NON SUPERVISEE. DES ALGORITHMES D'ESTIMATION PREALABLE A LA SEGMENTATION CONTEXTUELLE, TELS QUE EM, ICE, SEM, SONT ETUDIES. PUIS CES ESTIMATEURS VALABLES DANS LES CHAMPS STATIONNAIRES SONT ADAPTES AUX CHAMPS NON STATIONNAIRES. NOUS MENONS UNE COMPARAISON DES PERFORMANCES DES ESTIMATEURS SUIVANT DES CARACTERISTIQUES DU BRUIT. UNE ETUDE DE LA ROBUSTESSE DE LA SEGMENTATION CONTEXTUELLE EST EFFECTUEE, CE QUI EST UTILE POUR LE CHOIX D'UN ESTIMATEUR, AINSI QUE POUR LA DEFINITION D'UN COMPROMIS ENTRE LA PRECISION DE L'ESTIMATION ET LE TEMPS DE CALCUL. LA DEUXIEME PARTIE EST CONSACREE A LA DETECTION DE CONTOURS PAR FILTRAGE. UNE DEFINITION DES CONTOURS UTILISANT L'ORDRE DE DISCONTINUITE EST D'ABORD PROPOSEE. LA METHODOLOGIE DE LA DETECTION DE CONTOURS D'ORDRE 0 (CONTOUR ECHELON) EST GENERALISEE AUX CONTOURS DE DISCONTINUITE D'ORDRE QUELCONQUE. LE PROBLEME DE LA DETECTION DE CONTOURS EST AINSI REDUIT A LA RECHERCHE D'UN FILTRE DE LISSAGE OPTIMAL DONT LA FORME JOUE UN ROLE IMPORTANT. L'ACCENT EST DONC MIS SUR L'ETUDE DES FORMES DE FILTRES DE LISSAGE EXISTANTS. UN EXEMPLE DE CETTE GENERALISATION, LA DETECTION DU CONTOUR RAMPE, EST APPLIQUEE AUX IMAGES SIMULEES ET IMAGES REELLES. LA TROISIEME PARTIE EST CONSACREE A LA MISE EN PARALLELE DES DEUX FAMILLES DE METHODES. APRES UNE ETUDE SUR LEURS PROFILS DIFFERENTS ET POINTS COMMUNS DU POINT DE VUE THEORIQUE, L'OBJECTIF PRINCIPAL EST LA COMPARAISON DE LA QUALITE, TANT VISUELLE QUE SELON DES CRITERES OBJECTIFS, DES CONTOURS OBTENUS PAR DEUX FAMILLES DE METHODES. CETTE ETUDE MET EN LUMIERE LES DIFFERENCES DE COMPORTEMENT DES DEUX FAMILLES DE METHODES, ET PEUT AINSI SERVIR A LA DECISION QUANT AU CHOIX DE LA METHODE LA PLUS APPROPRIEE EN FONCTION DE PROPRIETES OBJECTIVES DES IMAGES

Download or read book Segmentation d'images written by Fouad Sabry and published by One Billion Knowledgeable. This book was released on 2024-05-11 with total page 150 pages. 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. Comment vous en bénéficierez (I) Informations et validations sur les sujets suivants : Chapitre 1 : Segmentation d'images Chapitre 2 : Détection des contours Chapitre 3 : Transformation de caractéristiques invariantes d'échelle Chapitre 4 : Seuil (traitement d'image) Chapitre 5 : Méthode d'Otsu Chapitre 6 : Détection de coin Chapitre 7 : Coupes graphiques en vision par ordinateur Chapitre 8 : Décalage moyen Chapitre 9 : Segmentation de plage Chapitre 10 : Bassin versant (traitement d'image) (II) Répondre aux principales questions du public sur la segmentation d'images.

Download or read book Smart Health written by Andreas Holzinger and published by Springer. This book was released on 2015-02-24 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prolonged life expectancy along with the increasing complexity of medicine and health services raises health costs worldwide dramatically. Whilst the smart health concept has much potential to support the concept of the emerging P4-medicine (preventive, participatory, predictive, and personalized), such high-tech medicine produces large amounts of high-dimensional, weakly-structured data sets and massive amounts of unstructured information. All these technological approaches along with “big data” are turning the medical sciences into a data-intensive science. To keep pace with the growing amounts of complex data, smart hospital approaches are a commandment of the future, necessitating context aware computing along with advanced interaction paradigms in new physical-digital ecosystems. The very successful synergistic combination of methodologies and approaches from Human-Computer Interaction (HCI) and Knowledge Discovery and Data Mining (KDD) offers ideal conditions for the vision to support human intelligence with machine learning. The papers selected for this volume focus on hot topics in smart health; they discuss open problems and future challenges in order to provide a research agenda to stimulate further research and progress.

Book Synopsis Flow Sensing in Air and Water by : Horst Bleckmann
Download or read book Flow Sensing in Air and Water written by Horst Bleckmann and published by Springer Science & Business Media. This book was released on 2014-01-22 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, leading scientists in the fields of sensory biology, neuroscience, physics and engineering explore the basic operational principles and behavioral uses of flow sensing in animals and how they might be applied to engineering applications such as autonomous control of underwater or aerial vehicles. Although humans possess no flow-sensing abilities, countless aquatic (e.g. fish, cephalopods and seals), terrestrial (e.g. crickets and spiders) and aerial (e.g. bats) animals have flow sensing abilities that underlie remarkable behavioral feats. These include the ability to follow silent hydrodynamic trails long after the trailblazer has left the scene, to form hydrodynamic images of their environment in total darkness, and to swim or fly efficiently and effortlessly in the face of destabilizing currents and winds.

Book excerpt: This book constitutes the refereed proceedings of the Third International Workshop on Mining Complex Data, MCD 2007, held in Warsaw, Poland, in September 2007, co-located with ECML and PKDD 2007. The 20 revised full papers presented were carefully reviewed and selected; they present original results on knowledge discovery from complex data. In contrast to the typical tabular data, complex data can consist of heterogenous data types, can come from different sources, or live in high dimensional spaces. All these specificities call for new data mining strategies.

Book excerpt: This volume of the CRM Conference Series is based on a carefully refereed selection of contributions presented at the "11th International Symposium on Quantum Theory and Symmetries", held in Montreal, Canada from July 1-5, 2019. The main objective of the meeting was to share and make accessible new research and recent results in several branches of Theoretical and Mathematical Physics, including Algebraic Methods, Condensed Matter Physics, Cosmology and Gravitation, Integrability, Non-perturbative Quantum Field Theory, Particle Physics, Quantum Computing and Quantum Information Theory, and String/ADS-CFT. There was also a special session in honour of Decio Levi. The volume is divided into sections corresponding to the sessions held during the symposium, allowing the reader to appreciate both the homogeneity and the diversity of mathematical tools that have been applied in these subject areas. Several of the plenary speakers, who are internationally recognized experts in their fields, have contributed reviews of the main topics to complement the original contributions. .
