The imaging of cultural heritage objects has helped to drive many imaging developments. This talk will briefly round-up personal experiences of building high resolution, colorimetric and 3D object systems during five large European projects. Recently there has been a growing interest in reflectance transformation imaging, where systems with many light positions are used to create images which can be viewed with varying light angles. This has proven to be useful in the study of archaeological objects with subtle surface textures which are not rendered well with a single image. Several “dome” based systems have been made using high power white LEDs and off the shelf digital SLR cameras have been produced for campaigns to image clay tablets. The designs and results will be discussed with examples from the Ashmolean Museum in Oxford.

Kirk Martinez is a Reader in Electronics and Computer Science, University of Southampton. He has a PhD in Image Processing from the University of Essex. He previously ran the MA in Computer Applications for History of Art in Birkbeck College London while working on a variety of European imaging projects. This included VASARI (High resolution colorimetric imaging of art), MARC (image and print), ACOHIR (3D objects), Viseum (IIPimage viewer) projects. He went on to Content-based retrieval and semantic web applications for museums (Artiste, SCULPTEUR, eCHASE). He now mainly works on Sensor networks for the environment: Glacsweb and Internet of Things. He founded the VIPS image processing library and co-designed RTI imaging systems as part of an AHRC project.
