Project Description

Virtual Vellum was an e-Science demonstrator project with the aim of promoting and demonstrating the use of technology within arts and humanities research. It investigated technologies that facilitate the retrieval, manipulation and annotation/hotspotting of very high resolution image datasets (typically greater than 8k x 6k pixels). Each dataset may consist of many hundred images, such as those from digitised manuscripts. The Froissart Manuscript Project provided the initial collection of images for the development process, however the viewing environment provided a generic viewing tool for researchers and is able to handle arbitrary image collections.

Flexibility in terms of accessing image datasets has been given by including the ability to retrieve data from a local hard drive, over the internet, and via a Data Grid using Storage Resource Broker (this primarily made use of the White Rose Grid and the Worldwide Universities Network, WUN). Motivated by the potential bandwidth issues associated with retrieving large images over a network, the effectiveness of encoding the images as JPEG 2000 was assessed and implemented within the project.

Further benefits and features of the Virtual Vellum project include:

  • Entirely written in Java Version 1.2 (this includes the JPEG 2000 decoder and multiple view user interface)
  • Open source access to the viewing tool
  • Computer platform independence
  • Single and multiple views for comparing different images

Virtual Vellum therefore provides an ideal tool for collaborative Access Grid seminars and standalone conference presentations and lectures. VV was rolled out during a live medieval exhibition connecting the Royal Armouries at Leeds with its premises at the Tower of London and Louisville, Kentucky between April and June 2007. During the exhibition, the audience was invited to use the viewing tool to interact with the Froissart manuscript images, which would otherwise be inaccessible because of the rare and fragile state of the original manuscripts.

Duration: June 2006 – November 2006
