Languages : en
Pages : 378

Book Description
Cet ouvrage collectif recense les dernières avancées dans le domaine de l'analyse automatique des images numériques couleur. Destiné aux chercheurs, ingénieurs R&D et étudiants en Master ou Doctorat, il constitue un état de l'art critique et le plus exhaustif possible sur les problématiques scientifiques soulevées par les différentes étapes constituant une chaîne de traitement des images couleur. Le filtrage et la segmentation des images fixes sont abordés par des techniques récentes telles que les outils morphologiques couleur, les équations aux dérivées partielles, l'algèbre quaternionique ou l'analyse de graphes. La caractérisation des textures couleur est traitée par la prédiction linéaire ou des descripteurs statistiques. La reconnaissance d'objets fixes ou en mouvement dans des vidéos couleur nécessite d'utiliser des attributs invariants aux conditions d'éclairage. Une attention particulière a été apportée aux espaces couleur, et notamment ceux séparant la luminance de la chrominance.

Digital Image Processing with C++

Digital Image Processing with C++ PDF Author: David Tschumperle
Publisher: CRC Press
ISBN: 1000831426
Category : Computers
Languages : en
Pages : 309

Book Description
Digital Image Processing with C++ presents the theory of digital image processing, and implementations of algorithms using a dedicated library. Processing a digital image means transforming its content (denoising, stylizing, etc.), or extracting information to solve a given problem (object recognition, measurement, motion estimation, etc.). This book presents the mathematical theories underlying digital image processing, as well as their practical implementation through examples of algorithms implemented in the C++ language, using the free and easy-to-use CImg library. Chapters cover in a broad way the field of digital image processing and proposes practical and functional implementations of each method theoretically described. The main topics covered include filtering in spatial and frequency domains, mathematical morphology, feature extraction and applications to segmentation, motion estimation, multispectral image processing and 3D visualization. Students or developers wishing to discover or specialize in this discipline, teachers and researchers wishing to quickly prototype new algorithms, or develop courses, will all find in this book material to discover image processing or deepen their knowledge in this field.

Digital Filters Design for Signal and Image Processing

Digital Filters Design for Signal and Image Processing PDF Author: Mohamed Najim
Publisher: John Wiley & Sons
ISBN: 1118614682
Category : Technology & Engineering
Languages : en
Pages : 259

Book Description
Dealing with digital filtering methods for 1-D and 2-D signals, this book provides the theoretical background in signal processing, covering topics such as the z-transform, Shannon sampling theorem and fast Fourier transform. An entire chapter is devoted to the design of time-continuous filters which provides a useful preliminary step for analog-to-digital filter conversion. Attention is also given to the main methods of designing finite impulse response (FIR) and infinite impulse response (IIR) filters. Bi-dimensional digital filtering (image filtering) is investigated and a study on stability analysis, a very useful tool when implementing IIR filters, is also carried out. As such, it will provide a practical and useful guide to those engaged in signal processing.

Image Synthesis

Image Synthesis PDF Author: Michel Bret
Publisher: Springer Science & Business Media
ISBN: 9401125686
Category : Computers
Languages : en
Pages : 297

Book Description
The images produced by means ofcomputers have invaded our daily lives. One has but to see the "identification logos" of most television broadcasts or some advenisement "spots" to be convinced of this. This proves that the synthesis ofimages has reached maturity. The progress that has been made in the last few years allows one to predict the use ofrealistic illustrations in more and more domains ofapplication. It is thus understandable that more and more people seek to understand how these images are produced. Such a person may be an amateur who likes to understand in a general way the processing involved, or he may be a computer scientist who wants to develop some new application using graphics procedures. This book by Michel Bret meets these desires by giving a complete overview of the techniques of image synthesis by computer. The different stages of the creation of a numerical image are explained in detail, and they are accompanied by descriptions of the most modem methods. Thus the geometrical models that are described go from those with plane polygonal facets, via surfaces of all types, to systems of panicles. Visualization is treated in complete detail, and due attention is given to all the various roads that lead to a realistic image: simple projections on the basis of wire-frame models, the elimination of hidden pans, and fmally the modelling oflight and its effects.

Vidéo 3D : Capture, traitement et diffusion 

Vidéo 3D : Capture, traitement et diffusion  PDF Author: LUCAS Laurent
Publisher: Lavoisier
ISBN: 2746295458
Category : 3-D video (Three-dimensional imaging)
Languages : en
Pages : 457

Book Description
Les médias 3D relief, leur capture, leur retransmission en relief, possiblement en direct, sont aujourd’hui disponibles et portent l’évolution attendue pour la télévision et l’Internet. Ces technologies (« télévision 3D », « free viewpoint TV » ou « Vidéo 3D »), impactent toute la chaîne audiovisuelle : · les techniques d'acquisition relief sont plus variées · les scènes sont représentées par des structures numériques plus ou moins informatives : vidéos multi-vues sans/avec profondeur, modèles 3D · la reconstruction extrait lesdites représentations des vidéos multi-vues, · leur compression facilite la diffusion des médias, · l'affichage (auto-)stéréoscopique, avec/sans adaptation/enrichissement et/ou synthèse de vues intermédiaires, permet l’expérience visuelle immersive ciblée. La vidéo 3D recouvre donc de multiples facettes. Visant à donner aux étudiants une vision d’ensemble du sujet et aux chercheurs un texte de référence actuel aussi complet que possible, cet ouvrage en présente les principaux développements relevant de domaines variés : mathématiques appliquées, vision par ordinateur, informatique graphique, réalité virtuelle, psychophysique et physiologie de la vision humaine...

Fundamentals of Instrumentation and Measurement

Fundamentals of Instrumentation and Measurement PDF Author: Dominique Placko
Publisher: John Wiley & Sons
ISBN: 1118613643
Category : Technology & Engineering
Languages : en
Pages : 369

Book Description
This title presents the general principles of instrumentation processes. It explains the theoretical analysis of physical phenomena used by standard sensors and transducers to transform a physical value into an electrical signal. The pre-processing of these signals through electronic circuits – amplification, signal filtering and analog-to-digital conversion – is then detailed, in order to provide useful basic information. Attention is then given to general complex systems. Topics covered include instrumentation and measurement chains, sensor modeling, digital signal processing and diagnostic methods and the concept of smart sensors, as well as microsystem design and applications. Numerous industrial examples punctuate the discussion, setting the subjects covered in the book in their practical context.
