Digital imaging techniques have been rapidly adopted within archaeology and cultural heritage practice for the accurate documentation of cultural artefacts. But what is a digital image, and how does it relate to digital photography? The authors of this book take a critical look at the practice and techniques of digital imaging from the stance of digital archaeologists, cultural heritage practitioners and digital artists. Borrowing from the feminist scholar Karen Barad, the authors ask what happens when we diffract the formal techniques of archaeological digital imaging through a different set of disciplinary concerns and practices. Diffracting exposes the differences between archaeologists, heritage practitioners and artists, and foregrounds how their differing practices and approaches enrich and inform each other. How might the digital imaging techniques used by archaeologists be adopted by digital artists, and what are the potentials associated with this adoption? Under the gaze of fine artists, what happens to the fidelity of the digital images made by archaeologists, and what new questions do we ask of the digital image? How can the critical approaches and practices of fine artists inform the future practice of digital imaging in archaeology and cultural heritage? Diffracting Digital Images will be of interest to students and scholars in archaeology, cultural heritage studies, anthropology, fine art, digital humanities, and media theory.

In recent years, Moore's law has fostered the steady growth of the field of digital image processing, though the computational complexity remains a problem for most of the digital image processing applications. In parallel, the research domain of optical image processing has matured, potentially bypassing the problems digital approaches were suffering and bringing new applications. The advancement of technology calls for applications and knowledge at the intersection of both areas but there is a clear knowledge gap between the digital signal processing and the optical processing communities. This book covers the fundamental basis of the optical and image processing techniques by integrating contributions from both optical and digital research communities to solve current application bottlenecks, and give rise to new applications and solutions. Besides focusing on joint research, it also aims at disseminating the knowledge existing in both domains. Applications covered include image restoration, medical imaging, surveillance, holography, etc...

This book is concerned with the theory and application of fractal geometry in digital imaging. Throughout the book, a series of new approaches to defining fractals are illustrated, such as the analysis of the fractal power spectrum and the use of fractional differentials. Several new algorithms and applications are also discussed and applied to real life images. Fractal Geometry in Digital imaging will appeal to postgraduates, researchers and practitioners in image processing, mathematics and computing, information technology and engineering.

The Routledge Handbook of Archaeology and the Media in the 21st Century presents diverse international perspectives on what it means to be an archaeologist and to conduct archaeological research in the age of digital and mobile media. This volume analyses the present‐day use of new and old media by professional and academic archaeology for leisure, academic study and/or public engagement, and attempts to provide a broad survey of the use of media in a wider global archaeological context. It features work on traditional paper media, radio, podcasting, film, television, contemporary art, photography, video games, mobile technology, 3D image capture, digitization and social media. Themes explored include archaeology and traditional media, archaeology in a digital age, archaeology in a post‐truth era and the future of archaeology. Such comprehensive coverage has not been seen before, and the focus on 21st‐century concerns and media consumption practices provides an innovative and original approach. The Routledge Handbook of Archaeology and the Media in the 21st Century updates the interdisciplinary field of media studies in archaeology and will appeal to students and researchers in multiple fields including contemporary, public, digital, and media archaeology, and heritage studies and management. Television and film producers, writers and presenters of cultural heritage will also benefit from the many entanglements shared here between archaeology and the contemporary media landscape.

A few years ago, a real break-through happened in observational astronomy: the un derstanding of the effect of atmospheric turbulence on the structure of stellar images, and of ways to overcome this dramatic degradation. This opened a route to diffraction-limited observations with large telescopes in the optical domain. Soon, the first applications of this new technique led to some outstanding astrophysical results, both at visible and infrared wavelengths. Yet, the potential of interferometric observations is not fully foreseeable as the first long-baseline arrays of large optical telescopes are being built or cOIIllnissioned right now. In this respect a comparison with the evolution of radio-astronomy is tempting. From a situation where, in spite of the construction of giant antennas, low angular resolution was prevailing, the introduction of long baseline and very long baseline interferometry and the rapid mastering of sophisticated image reconstruction techniques, have brought on a nearly routine basis high dynamic range images with milliarcseconds resolution. This, of course, has completely changed our views of the radio sky.

The scientific photography of small subjects encompasses the domains of close-up photography, macrophotography and photomacrography, and is a primary documentation tool in many research fields. This book concentrates on the choice and practical use of digital cameras, lenses and related equipment of types commonly available at research institutions and museums. The described techniques are suitable for subject sizes between approximately half a millimeter and half a meter, and differ from those used in general photography and microscopy. The intended audience of this book includes professional scientific photographers, scientists and students who need to carry out photography in support of their own research or as part-time scientific photographers at a research institution, and advanced amateur photographers who wish to master these techniques.

Spectroscopy, Diffraction and Tomography in Art and Heritage Science gives an overview of the main spectroscopy and diffraction techniques currently available for cultural heritage research. It starts with an introductory, general discussion of spectroscopy and diffraction and the kinds of information they can give. Further sections deal with, respectively, typical laboratory methods, mobile equipment, and large-scale instruments and infrastructural methods. The work concludes with comments on combining and comparing multiple techniques, sources of error, and limitations of the analytical methods. - Explains spectroscopy and diffraction techniques in detail, yet remains accessible to those without a chemistry or physics background - Provides explanations of commonly used terms, such as destructive, non-destructive, non-invasive, in-situ, and ex-situ, and their sometimes-misleading origins - Includes real-world examples that demonstrate how each technique is used in the field - Highlights the complementary use of different analytical techniques in fully interpreting the data
