Описание: The field of multimedia is unique in offering a rich and dynamic forum for researchers from “traditional” fields to collaborate and develop new solutions and knowledge that transcend the boundaries of individual disciplines. Despite the prolific research activities and outcomes, however, few efforts have been made to develop books that serve as an introduction to the rich spectrum of topics covered by this broad field. A few books are available that either focus on specific subfields or basic background in multimedia. Tutorial-style materials covering the active topics being pursued by the leading researchers at frontiers of the field are currently lacking.In 2015, ACM SIGMM, the special interest group on multimedia, launched a new initiative to address this void by selecting and inviting 12 rising-star speakers from different subfields of multimedia research to deliver plenary tutorial-style talks at the ACM Multimedia conference for 2015. Each speaker discussed the challenges and state-of-the-art developments of their prospective research areas in a general manner to the broad community. The covered topics were comprehensive, including multimedia content understanding, multimodal human-human and human-computer interaction, multimedia social media, and multimedia system architecture and deployment.Following the very positive responses to these talks, the speakers were invited to expand the content covered in their talks into chapters that can be used as reference material for researchers, students, and practitioners. Each chapter discusses the problems, technical challenges, state-of-the-art approaches and performances, open issues, and promising direction for future work. Collectively, the chapters provide an excellent sampling of major topics addressed by the community as a whole. This book, capturing some of the outcomes of such efforts, is well positioned to fill the aforementioned needs in providing tutorial-style reference materials for frontier topics in multimedia.At the same time, the speed and sophistication required of data processing have grown. In addition to simple queries, complex algorithms like machine learning and graph analysis are becoming common. And in addition to batch processing, streaming analysis of real-time data is required to let organizations take timely action. Future computing platforms will need to not only scale out traditional workloads, but support these new applications too.This book, a revised version of the 2014 ACM Dissertation Award winning dissertation, proposes an architecture for cluster computing systems that can tackle emerging data processing workloads at scale. Whereas early cluster computing systems, like MapReduce, handled batch processing, our architecture also enables streaming and interactive queries, while keeping MapReduce's scalability and fault tolerance. And whereas most deployed systems only support simple one-pass computations (e.g., SQL queries), ours also extends to the multi-pass algorithms required for complex analytics like machine learning. Finally, unlike the specialized systems proposed for some of these workloads, our architecture allows these computations to be combined, enabling rich new applications that intermix, for example, streaming and batch processing.We achieve these results through a simple extension to MapReduce that adds primitives for data sharing, called Resilient Distributed Datasets (RDDs). We show that this is enough to capture a wide range of workloads. We implement RDDs in the open source Spark system, which we evaluate using synthetic and real workloads. Spark matches or exceeds the performance of specialized systems in many domains, while offering stronger fault tolerance properties and allowing these workloads to be combined. Finally, we examine the generality of RDDs from both a theoretical modeling perspective and a systems perspective.This version of the dissertation makes corrections throughout the text and adds a new s

Описание: The twenty-first century has seen a breathtaking expansion of statistical methodology, both in scope and in influence. 'Big data', 'data science', and 'machine learning' have become familiar terms in the news, as statistical methods are brought to bear upon the enormous data sets of modern science and commerce. How did we get here? And where are we going? This book takes us on an exhilarating journey through the revolution in data analysis following the introduction of electronic computation in the 1950s. Beginning with classical inferential theories - Bayesian, frequentist, Fisherian - individual chapters take up a series of influential topics: survival analysis, logistic regression, empirical Bayes, the jackknife and bootstrap, random forests, neural networks, Markov chain Monte Carlo, inference after model selection, and dozens more. The distinctly modern approach integrates methodology and algorithms with statistical inference. The book ends with speculation on the future direction of statistics and data science.
This book proposes new algorithms to ensure secured communications and prevent unauthorized data exchange in secured multimedia systems. Focusing on numerous applications’ algorithms and scenarios, it offers an in-depth analysis of data hiding technologies including watermarking, cryptography, encryption, copy control, and authentication. The authors present a framework for visual data hiding technologies that resolves emerging problems of modern multimedia applications in several contexts including the medical, healthcare, education, and wireless communication networking domains. Further, it introduces several intelligent security techniques with real-time implementation.
As part of its comprehensive coverage, the book discusses contemporary multimedia authentication and fingerprinting techniques, while also proposing personal authentication/recognition systems based on hand images, surveillance system security using gait recognition, face recognition under restricted constraints such as dry/wet face conditions, and three-dimensional face identification using the approach developed here.
This book equips perception technology professionals with the latest technologies, techniques, and strategies for multimedia security systems, offering a valuable resource for engineers and researchers working to develop security systems.

Описание: Die Mensch und Computer ist eine vom Fachbereich Mensch-Computer-Interaktion der Gesellschaft fur Informatik (GI) initiierte und seit 2001 jahrlich stattfindende Fachtagungsreihe zu Mensch-Computer-Interaktion. Hier treffen sich Personen aus Wissenschaft und Praxis, um neueste Forschungsergebnisse zu diskutieren, Erfahrungen auszutauschen und neue Produkte und Methoden kennen zu lernen. Die Tagung bietet Einblicke in Entwicklungen in den Bereichen Usability, User Experience, Mensch-Computer-Interaktion, Computer-Supported Cooperative Work und Gestaltung interaktiver Medien. Die Mensch und Computer 2015 in Stuttgart steht unter dem Motto "Gemeinsam- Arbeit - Erleben". Dieses Motto greift die Entwicklungen auf, dass sich die klare zeitliche Trennung zwischen Arbeit und Freizeit aufzulosen beginnt. Deshalb werden in Zukunft Benutzungsschnittstellen und Systeme erforderlich die Erlebnisse in allen Lebenslagen unterstutzen. Im Bereich Mensch und Computer spielt aber nicht nur die Interaktion eines oder mehrerer Benutzer mit einem Computer eine Rolle, sondern auch die Nutzung von Computersystemen zur Unterstutzung der Kommunikation zwischen Menschen (Mensch-Computer-Mensch-Interaktion). Manche Anwendung bleibt in Gerate integriert quasi unsichtbar, mit anderen muss bewusst unter Nutzung vielfaltiger Ein- und Ausgabemedien interagiert werden. Der wissenschaftliche Teil der Tagung Mensch und Computer nimmt diese technologischen Entwicklungen und Anforderungen zum Anlass, Beitrage von Forschern der Fachdisziplinen “Mensch-Computer-Interaktion” sowie “Rechnergestutzte Gruppenarbeit (CSCW, Computer-Supported Cooperative Work)” und “Social Computing” zur Entwicklung von neuen Interaktionskonzepten vorzustellen und kritisch zu diskutieren. Der Tagungsband beschreibt vielfaltige Systeme und Anwendungen, die Arbeits- und Lernprozesse unterstutzen, die Freizeit begleiten und unterhalten, Kommunikation und Koordination ermoglichen und verbessern.
