Digital Image Corruption - Where It Comes From and How to Detect It

Series
Digital Humanities at Oxford Summer School
Embed
Chris Powell, Ashmolean Museum, University of Oxford, gives a talk for the 2015 DHOXSS.
Digital images (photographs) present a significant resource for the Digital Humanities practitioner; individual collections can number in the hundreds of thousands, and can use a variety of encoding methods. These resources can be the result of decades of work and at the very least would be extremely expensive to replace in the event of a disaster. The lecture firstly looks at the methods commonly employed to safeguard an image archive, for example multiple copies across different media types, mirroring. This is followed by an examination of each of these, and identifies issues with each, be they procedural or physical. Next the effects of the issues on image corruption are explored, together with examples of the resultant image corruption on different image encoding methods. Following the observation that most images in an archive are not viewed on a regular basis,methods of detecting corrupted images in an archive are presented, including a visual TIFF image scanner developed at the Ashmolean. Finally, some recommendations are made which will help to ensure the accurate preservation of a digital image archive.

Digital Transformations

Series
Digital Humanities at Oxford Summer School
Embed
Panel discussion for th DHOXSS 2015.
David De Roure, Oxford e-Research Centre, University of Oxford (Chair), Lucie Burgess, Bodleian Libraries, University of Oxford, Tim Crawford, Computing Department, Goldsmiths, University of London, Andrew Prescott, University of Glasgow, and Jane Winters, Institute of Historical Research, University of London.
We are transforming our individual and collective lives through digital technology, in the ways we communicate and create our knowledge and understanding of the world and the human record of it. How is research in the Humanities leading this potential and responding to its limits? Is current practice in teaching, training, learning, research, storing, curating, and delivering knowledge fit to support, communicate, and encourage citizen participation in these developments? How do they affect our infrastructure requirements, now and into the future?

How I Learned to Stop Worrying and Love the Digital

Series
Digital Humanities at Oxford Summer School
Embed
Jane Winters, Institute of Historical Research, University of London, gives the opening keynote talk for the 2015 DHOXSS.
We are all digital researchers now. Our methods of working, the sources that we choose to use, the ways in which we interact with those sources, and the ways in which we communicate our research findings have all been profoundly affected by the digital. Whether we are interested in epigraphic and papyrological texts or in the history of the web, in Anglo-Saxon charters or in eighteenth-century court records, in text or in moving image, digital tools and methods have the capacity to transform our understandings and offer new insights into old and as yet undreamt of questions. The development of the digital has also supported greater collaboration, openness and interdisciplinarity in humanities research, both by making this technologically possible and by altering the types and breadth of knowledge required to run a successful research project. Drawing on a range of projects and initiatives that encompass data both big and small, this presentation will highlight the possibilities afforded by the digital and the skills that we need to develop in order to shape the evolution of digital humanities research in the coming months and years.
