The Mojette Transform
Applied sciences in the 20th century have developed and used unitary transforms for concentrating energy. Now, the challenge lies in the expression and use of redundancy to build redundant systems. The Mojette transform is a very simple transform using only additions but with strong properties that break this challenge. The first part of the book gives the basics of the Mojette transform both mathematically and the corresponding optimal algorithms. The second part exemplifies its use through different fields: image representation, watermarking, medical imaging, distributed storage, information and cryptography. This book about a discrete exact Radon transform explains how to usefully produce and cope with redundancy for solving 21st century problems
Discrete Geometry for Computer Imagery
This book constitutes the refereed proceedings of the 19th IAPR International Conference on Discrete Geometry for Computer Imagery, DGCI 2016, held in Nantes, France, in April 2016. The 32 revised full papers presented together with 2 invited talks were carefully selected from 51 submissions. The papers are organized in topical sections on combinatorial tools; discretization; discrete tomography; discrete and combinatorial topology; shape descriptors; models for discrete geometry; circle drawing; morphological analysis; geometric transforms; and discrete shape representation, recognition and analysis.
Predicting Perceptions: Proceedings of the 3rd International Conference on Appearance
Beauty is in the eye of the beholder, and appearance lies in the mind of the observer. The latter is playing an increasingly important role in nearly all of our buying decisions: it informs us as to the quality of an automobile cabin, the desirability of an iPhone, the handle of a woollen sweater - the list is endless.Given the exponential rise in internet commerce and the ubiquity of smart devices, the ability to predict buyers' perceptions formed from interaction with digital media is maybe more important than those obtained by handling the real article.Thus, the science of appearance metrology is becoming increasingly critical. It concerns the development of methodologies, procedures, and equipment which allow us to predict observers' perceptions. The field is therefore highly multidisciplinary: physical measurement, psychophysics, media generation, image processing, statistics, and vision science.This book is a compilation of recent research relating to perception and appearance.
Multimedia Forensics and Security
As information technology is rapidly progressing, an enormous amount of media can be easily exchanged through Internet and other communication networks. Increasing amounts of digital image, video, and music have created numerous information security issues and is now taken as one of the top research and development agendas for researchers, organizations, and governments worldwide. Multimedia Forensics and Security provides an in-depth treatment of advancements in the emerging field of multimedia forensics and security by tackling challenging issues such as digital watermarking for copyright protection, digital fingerprinting for transaction tracking, and digital camera source identification.
Information Systems Design and Intelligent Applications
The third international conference on INformation Systems Design and Intelligent Applications (INDIA – 2016) held in Visakhapatnam, India during January 8-9, 2016. The book covers all aspects of information system design, computer science and technology, general sciences, and educational research. Upon a double blind review process, a number of high quality papers are selected and collected in the book, which is composed of three different volumes, and covers a variety of topics, including natural language processing, artificial intelligence, security and privacy, communications, wireless and sensor networks, microelectronics, circuit and systems, machine learning, soft computing, mobile c...
Elements Of Digital Geometry, Mathematical Morphology, And Discrete Optimization
The author presents three distinct but related branches of science in this book: digital geometry, mathematical morphology, and discrete optimization. They are united by a common mindset as well as by the many applications where they are useful. In addition to being useful, each of these relatively new branches of science is also intellectually challenging.The book contains a systematic study of inverses of mappings between ordered sets, and so offers a uniquely helpful organization in the approach to several phenomena related to duality.To prepare the ground for discrete convexity, there are chapters on convexity in real vector spaces in anticipation of the many challenging problems coming up in digital geometry. To prepare for the study of new topologies introduced to serve in discrete spaces, there is also a chapter on classical topology.The book is intended for general readers with a modest background in mathematics and for advanced undergraduate students as well as beginning graduate students.
Medical Imaging 2003
Proceedings of SPIE present the original research papers presented at SPIE conferences and other high-quality conferences in the broad-ranging fields of optics and photonics. These books provide prompt access to the latest innovations in research and technology in their respective fields. Proceedings of SPIE are among the most cited references in patent literature.
Modélisation psychovisuelle pour le tatouage des images
Le tatouage d'images est apparu dans le début des années 1990, dans le but de parer la copie illicite des données numériques. La protection des droits d'auteurs des images numériques est par ailleurs très liée à d'autres disciplines plus anciennes, telles que la stéganographie, la cryptographie ou l'authentification des données. Dans cette thèse, nous étudions principalement le taouage des images à des fins de protection de copyright, sans toutefois négliger les autres aspects cités précédemment...
