Considers the nature and status of contemporary cinema by way of a series of technological reflections on its pastArgues for a progressive historiography that looks forward, moving beyond the sense of anxiety and loss that has dominated accounts of cinema's postulated demiseDraws on the latest thinking on evolving screen technologies and media archaeology and the development of cognate areas such as memory studiesCharts the historical memory of cinema, with a view to considering how our engagement with, and understanding of, this history might be reconfigured in the present.Channelling a focus on the history of cinema into the present and beyond, Persistent Images: Encountering Film History in Contemporary Cinema explores the continuing resonance of the memory of cinema as revealed in the technological and aesthetic expressions of a range of experimental practices. With case studies of films that reflexively foreground and creatively reimagine the past, including Shirin (2008), Goodbye to Language (2014) and Francofonia (2015), the book demonstrates how the medium of film can look simultaneously backwards and forwards, encountering and reframing the past in the present, and offering new ways of thinking about both film history and contemporary cinema alike.

In tourism, strangers meet face to face. What do Tanzanian Maasai and Western tourists think when they meet? Using a combination of methods that has never been tried in anthropology, or in the field of tourism studies, this work provides novel theoretical insights into the images hosts and guests have of each other, and how their views relate to the interactions they experience. This compelling reflexive study uses video and Q method to contribute to the epistemology of anthropological research in tourism settings, and the construction of a new, more symmetrical anthropology. Dissertation. ***An important contribution to the growing field of the anthropology of tourism, an example of intense and methodical fieldwork, combined with theoretical acumen and deep reflexivity.--Prof. Dr Walter E. A. van Beek (Tilburg U.) (Series: Contributions to African Research / Beitr�¤ge zur Afrikaforschung, Vol. 76) [Subject: African Studies, Tourism Studies, Anthropology, Sociology]

Shrinking pixel sizes along with improvements in image sensors, optics, and electronics have elevated DSCs to levels of performance that match, and have the potential to surpass, that of silver-halide film cameras. Image Sensors and Signal Processing for Digital Still Cameras captures the current state of DSC image acquisition and signal processing technology and takes an all-inclusive look at the field, from the history of DSCs to future possibilities. The first chapter outlines the evolution of DSCs, their basic structure, and their major application classes. The next few chapters discuss high-quality optics that meet the requirements of better image sensors, the basic functions and performance parameters of image sensors, and detailed discussions of both CCD and CMOS image sensors. The book then discusses how color theory affects the uses of DSCs, presents basic image processing and camera control algorithms and examples of advanced image processing algorithms, explores the architecture and required performance of signal processing engines, and explains how to evaluate image quality for each component described. The book closes with a look at future technologies and the challenges that must be overcome to realize them. With contributions from many active DSC experts, Image Sensors and Image Processing for Digital Still Cameras offers unparalleled real-world coverage and opens wide the door for future innovation.

Over recent years there has been a vast expansion in the variety of imaging techniques available, and developments in machine specifications continue apace. If radiologists and radiographers are to obtain optimal image quality while minimising exposure times, a good understanding of the fundamentals of the radiological science underpinning diagnostic imaging is essential. The second edition of this well-received textbook continues to cover all technical aspects of diagnostic radiology, and remains an ideal companion during examination preparation and beyond. The content includes a review of basic science aspects of imaging, followed by a detailed explanation of radiological sciences, conventional x-ray image formation and other imaging techniques. The enormous technical advances in computed tomography, including multislice acquisition and 3D image reconstruction, digital imaging in the form of image plate and direct radiography, magnetic resonance imaging, colour flow imaging in ultrasound and positron radiopharmaceuticals in nuclear medicine, are all considered here. A chapter devoted to computers in radiology considers advances in radiology information systems and computer applications in image storage and communication systems. The text concludes with a series of general topics relating to diagnostic imaging. The content has been revised and updated throughout to ensure it remains in line with the Fellowship of the Royal College of Radiologists (FRCR) examination, while European and American perspectives on technology, guidelines and regulations ensure international relevance.

Designed for media professionals working across a broad range of formats, Developer's Digital Media Reference is an excellent reference guide for those keeping pace with this dynamic industry. As "convergence" between the World Wide Web, multimedia, and television production communities continues, there is an increased demand for professionals to familiarize themselves with the many new delivery contexts, including hybrid DVD (where digital video content and computer data live on the same disc), interactive TV, and streaming media. Developer's Digital Media Reference covers essential technologies such as SVG (scalable vector graphics), SMIL (Synchronized Multimedia Integration Language, a markup language for creating animations on the web), MPEG-4 (compression standard for streaming audio/video), and Dynamic Web Applications. In addition to serving as a quick-look-up guide, this text is organized to explain today's major media: server-based architectures, disc-based architectures, distribution architectures, and merging/shared architectures. Each topic is discussed in terms of the technological background-evolution, current tools, and production tips and techniques.
