Book Description
LE PROBLEME DE RESTITUTION D'UNE SCENE A PARTIR D'UNE IMAGE NUMERIQUE DEGRADEE, SANS INFORMATION A PRIORI, POSE DES DIFFICULTES D'ORDRE THEORIQUE ET PRATIQUE DUES AUX BRUITS SUR LES DONNEES. CE MEMOIRE PRESENTE UNE CONTRIBUTION A L'AUTOMATISATION DES OPERATIONS D'IDENTIFICATION DES SOURCES DE DEGRADATION, DE FILTRAGE ET DE RESTAURATION A PARTIR DE L'IMAGE 2-D OBSERVEE SEULE. LA MODELISATION DES SOURCES DE DEGRADATION PAR L'ETUDE DU MECANISME DE FORMATION DE L'IMAGE, D'UNE PART ET LA MODELISATION DES IMAGES 2-D PAR DES CHAMPS STOCHASTIQUES D'AUTRE PART SERVENT DE BASE A L'ELABORATION D'UN OUTIL D'ANALYSE ET AU DEVELOPPEMENT D'ALGORITHMES DE TRAITEMENT. DES ALGORITHMES DE FILTRAGE DE BRUITS, DE NATURES DIVERSES ET PLUS PARTICULIEREMENT LES BRUITS MULTIPLICATIFS, ONT ETE ETUDIES. L'UTILISATION D'OPERATEURS LOCAUX NOUS A PERMIS DE TENIR COMPTE DE L'ASPECT PRESERVATION DES CONTOURS. PLUSIEURS METHODES DE RESTAURATION D'IMAGES FLOUES, NOTAMMENT UN FILTRAGE DE KALMAN 2-D SEMI-RECURSIF, ONT ETE PROSPECTEES. UNE IDENTIFICATION DU FLOU BASEE SUR CELLE D'UN PROCESSUS ARMA ET UNE ESTIMATION DE LA NATURE DU BRUIT BASEE SUR LA NOTION D'HOMOGENEITE LOCALE SONT PROPOSEES; UN TRAITEMENT OPTIMAL APPROPRIE EST ENSUITE APPLIQUE. NOS RESULTATS SONT COMPARES AVEC CEUX OBTENUS A PARTIR D'ALGORITHMES CONNUS EN TRAITEMENT D'IMAGES.
Local Approximation Techniques in Signal and Image Processing
Author: Vladimir I︠A︡kovlevich KatkovnikPublisher: SPIE-International Society for Optical Engineering
ISBN:
Category : Computers
Languages : en
Pages : 584
Book Description
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.
Product Life-Cycle Management

Languages : en
Pages : 389
Book Description
This book gives a comprehensive view of the most recent major international research in the field of tolerancing, and is an excellent resource for anyone interested in Computer Aided Tolerating. It is organized into 4 parts. Part 1 focuses on the more general problems of tolerance analysis and synthesis, for tolerancing in mechanical design and manufacturing processes. Part 2 specifically highlights the simulation of assembly with defects, and the influence of tolerances on the quality of the assembly. Part 3 deals with measurement aspects, and quality control throughout the life cycle. Different measurement technologies and methods for estimating uncertainty are considered. In Part 4, different aspects of tolerancing and their interactions are explored, from the definition of functional requirement to measurement processes in a PLM approach.

Mining Complex Data
Author: Zbigniew W. RasPublisher: Springer Science & Business Media
ISBN: 3540684158
Category : Computers
Languages : en
Pages : 275
Book Description
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.
