[Termes IGN] séquence d'imagesRésumé : (auteur) The purpose of this work is to detect strong changes in spatial relationships between objects in video sequences, with a limited knowledge on the objects. First, a fuzzy representation of the objects is proposed based on low-level generic primitives. Furthermore, angle and distance histograms are used as examples to model the spatial relationships between two objects. Then, we estimate the distances between different angle or distance histograms during time. By analyzing the evolution of the spatial relationships during time, ruptures are detected in this evolution. Experimental results show that the proposed method can efficiently detect the ruptures in the spatial relationships, exploiting only low-level primitives. This constitutes a promising step towards event detection in videos, with few a priori models on the objects.

[Termes IGN] réseau permanent EUREFRésumé : (auteur) The EUREF (Reference Frame Sub-Commission for Europe) Permanent GNSS Network (EPN) serves as the backbone for the realization of, and access to, the European Terrestrial Reference System (ETRS89). The cumulative site positions and velocities for the EPN stations are used for national ETRS89 densifications and geo-information applications. EUREF has developed specific guidelines through which European countries ask validation of their national ETRS89 densification campaigns. Today, the majority of the European countries has passed this process and a large part of European National Mapping and Cartographic Agencies have officially adopted ETRS89. In addition, ETRS89 plays a fundamental role in INSPIRE (Infrastructure for Spatial Information in the European Community).
In the meantime, some geographical zones are experiencing considerable deformation, degrading the lifetime of their national ETRS89 realizations. In order to derive a cross-boundary European velocity model that can be applied by different countries on top of their validated ETRS89 realization (while keeping consistency with their neighboring countries) the EUREF Technical Working Group has set up two initiatives: the EPN densification project and the EUREF Working Group on Deformation Models.Numéro de notice : C2014-022 Affiliation des auteurs : LASTIG LAREG+Ext (2012-mi2018) Thématique : POSITIONNEMENT Nature : Communication nature-HAL : ComAvecCL&ActesPubliésIntl DOI : 10.1007/1345_2015_130 En ligne : https://doi.org/10.1007/1345_2015_130 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=90681

[Termes IGN] programmation informatiqueRésumé : (éditeur) Evolutionary Computing is the collective name for a range of problem-solving techniques based on principles of biological evolution, such as natural selection and genetic inheritance. These techniques are being increasingly widely applied to a variety of problems, ranging from practical applications in industry and commerce to leading-edge scientific research. This book presents the first complete overview of this exciting field aimed directly at lecturers and graduate and undergraduate students. It is also meant for those who wish to apply evolutionary computing to a particular problem or within a given application area. To this group the book is valuable because it presents EC as something to be used rather than just studied. Last, but not least, this book contains quick-reference information on the current state-of-the-art in a wide range of related topics, so it is of interest not just to evolutionary computing specialists but to researchers working in other fields.

[Termes IGN] série temporelleRésumé : (auteur) This paper is concerned with the spectral analysis of stochastic processes that are realvalued, one-dimensional, discrete-time, covariance-stationary, and which have a representation as a moving average (MA) process. In particular, we will review the meaning and interrelations of four fundamental quantities in the time and frequency domain, (1) the stochastic process itself (which includes filtered stochastic processes), (2) its autocovariance function, (3) the spectral representation of the stochastic process, and (4) the corresponding spectral distribution function, or if it exists, the spectral density function. These quantities will be viewed as forming the corners of a square (the “magic square of spectral and time series analysis”) with various connecting lines, which represent certain mathematical operations between them. To demonstrate the evaluation of these operations, we will discuss the example of a q-th order MA process.

[Termes IGN] UMLRésumé : (éditeur) The second edition of this textbook includes revisions based on the feedback on the first edition. In a new chapter the authors provide a concise introduction to the remainder of UML diagrams, adopting the same holistic approach as the first edition. Using a case-study-based approach for providing a comprehensive introduction to the principles of object-oriented design, it includes:
A sound footing on object-oriented concepts such as classes, objects, interfaces, inheritance, polymorphism, dynamic linking, etc.
A good introduction to the stage of requirements analysis
Use of UML to document user requirements and design
An extensive treatment of the design process
Coverage of implementation issues
Appropriate use of design and architectural patterns
Introduction to the art and craft of refactoring
Pointers to resources that further the reader's knowledge
The focus of the book is on implementation aspects, without which the learning is incomplete. This is achieved through the use of case studies for introducing the various concepts of analysis and design, ensuring that the theory is never separate from the implementation aspects. All the main case studies used in this book have been implemented by the authors using Java. An appendix on Java provides a useful short tutorial on the language.Note de contenu : 1- Introduction
