This book was released on 1996 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: DANS CETTE THESE, NOUS PROPOSONS UNE APPROCHE GENERALE DU RECALAGE 3D. LES DONNEES SONT APPROXIMEES PAR UNE SPLINE HIERARCHIQUE QUADRIQUE. LE RECALAGE EST DEFINI COMME LE MINIMUM D'UN CRITERE ROBUSTE DONT LA MINIMISATION EST EFFECTUEE PAR UN ALGORITHME D'HYPOTHESE/VERIFICATION SUR LES CARREAUX SPLINES REPRESENTANT LES DONNEES ET LE MODELE. DANS LA PREMIERE PARTIE, NOUS PROPOSONS UNE PREMIERE METHODE DE RECONSTRUCTION D'UNE SURFACE SPLINE HIERARCHIQUE. L'ESTIMATION DES PARAMETRES DE LA HIERARCHIE EST EFFECTUEE PAR L'INTERMEDIAIRE DE LA MINIMISATION D'UN CRITERE D'APPROXIMATION QUADRATIQUE. DANS LA DEUXIEME PARTIE, NOUS REPRENONS LE PROBLEME DE L'ESTIMATION DU MODELE SPLINE UNIFORME TENSORIEL DANS LE CADRE DU FILTRAGE NUMERIQUE. NOUS DEVELOPPONS DES ALGORITHMES ORIGINAUX BEAUCOUP PLUS EFFICACES, QUI PERMETTENT LA MINIMISATION AUX MOINDRES CARRES, L'AJOUT D'UN TERME REGULARISATION, LA REPRESENTATION DES DISCONTINUITES, ET UNE ESTIMATION INTRINSEQUE DU MODELE. DANS LA TROISIEME PARTIE, NOUS ABORDONS LE PROBLEME DU RECALAGE 3D A L'AIDE DE LA REPRESENTATION SPLINE QUE NOUS AVONS INTRODUITE. LE DEPLACEMENT, SOLUTION DU RECALAGE, EST DEFINI COMME LE MINIMUM D'UN CRITERE ROBUSTE. NOUS MONTRONS COMMENT UTILISER LES CARREAUX SPLINES ET LEUR STRUCTURE HIERARCHIQUE POUR AMELIORER ET ACCELERER CETTE MINIMISATION. NOUS RESOLVONS ENFIN TROIS PROBLEMES DE RECALAGE 3D : L'ESTIMATION DE LA POSITION D'UN ROBOT, LA RECONNAISSANCE D'UN MODELE DANS UNE SCENE ET LE RECALAGE DE DEUX VUES D'UN MEME OBJET. DE NOMBREUX EXEMPLES DE RECONSTRUCTION DE SURFACE ET DE RECALAGE VIENNENT ILLUSTRER NOTRE TRAVAIL. EN TESTANT NOS ALGORITHMES SUR DES IMAGES ISSUES DE QUATRE CAPTEURS DIFFERENTS, TRAITANT DE CONTEXTES VARIES, TELS QUE LA ROBOTIQUE D'INTERIEUR, OU LA MODELISATION CAO FINE, NOUS SOUHAITONS MONTRER LA GENERALITE ET L'EFFICACITE DE NOTRE APPROCHE.

Download or read book Local Approximation Techniques in Signal and Image Processing written by Vladimir I︠A︡kovlevich Katkovnik and published by SPIE-International Society for Optical Engineering. This book was released on 2006 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Among others, the book addresses sensorless control techniques, modulation strategies, parameter identification, artificial intelligence, operation under harsh or failure conditions, and modelling of electric or magnetic quantities in electric machines. Several chapters give an insight into the problem of minimizing losses in electric machines and increasing the overall energy efficiency of electric drives.
Download or read book Applied Signal Processing written by Thierry Dutoit and published by Springer Science & Business Media. This book was released on 2010-06-10 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applied Signal Processing: A MATLAB-Based Proof of Concept benefits readers by including the teaching background of experts in various applied signal processing fields and presenting them in a project-oriented framework. Unlike many other MATLAB-based textbooks which only use MATLAB to illustrate theoretical aspects, this book provides fully commented MATLAB code for working proofs-of-concept. The MATLAB code provided on the accompanying online files is the very heart of the material. In addition each chapter offers a functional introduction to the theory required to understand the code as well as a formatted presentation of the contents and outputs of the MATLAB code. Each chapter exposes how digital signal processing is applied for solving a real engineering problem used in a consumer product. The chapters are organized with a description of the problem in its applicative context and a functional review of the theory related to its solution appearing first. Equations are only used for a precise description of the problem and its final solutions. Then a step-by-step MATLAB-based proof of concept, with full code, graphs, and comments follows. The solutions are simple enough for readers with general signal processing background to understand and they use state-of-the-art signal processing principles. Applied Signal Processing: A MATLAB-Based Proof of Concept is an ideal companion for most signal processing course books. It can be used for preparing student labs and projects.

Download or read book Measurement of Cardiac Deformations from MRI Physical and Mathematical Models written by A.A. Amini and published by Springer Science & Business Media. This book was released on 2001-12-31 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurement of Cardiac Deformations from MRI: Physical and Mathematical Models describes the latest imaging and imag analysis techniques that have been developed at leading centers for the visualization, analysis, and understanding of normal and abnormal cardiac motion with magnetic resonance imaging (MRI). The use of MRI in measuring cardiac motion is particularly important because MRI is non-invasive, and it is the only modality capable of imaging detailed intramural motion within the myocardium. Biomedical engineers, medical physicists, computer scientists, and physicians interested in learning about the latest advances in cardiovascular MRI should find this book to be a valuable educational resource. In particular, it is more tutorial in nature than most of the technical papers where the research was originally published. Practitioners and researchers working in the field of cardiovascular MRI will find the book to be filled with practical technical details and references to other work, enabling the implementation of existing methods and serving as a basis for further research in the area.

Download or read book Farm Profits and Adoption of Precision Agriculture written by U.s. Department of Agriculture and published by Createspace Independent Publishing Platform. This book was released on 2017-02-15 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precision agriculture (PA) and its suite of information technologies-such as soil and yield mapping using a global positioning system (GPS), GPS tractor guidance systems, and variable-rate input application-allow farm operators to fine-tune their production practices. Access to detailed, within-field information can decrease input costs and increase yields. USDA's Agricultural Resource Management Survey shows that these PA technologies were used on roughly 30 to 50 percent of U.S. corn and soybean acres in 2010-12. Previous studies suggest that use of PA is associated with higher profits under certain conditions, but aggregate estimates of these gains have not been available. In this report, a treatment-effects model is developed to estimate factors associated with PA technology adoption rates and the impacts of adoption on profits. Labor and machinery used in production and certain farm characteristics, like farm size, are associated with adoption as well as with two profit measures, net returns and operating profits. The impact of these PA technologies on profits for U.S. corn producers is positive, but small. Keywords: Crop production information technologies, precision agriculture, variablerate technology, soil tests, global positioning system maps, guidance systems.
