Digital Media Group
This group carries out research in the creation, capture, processing,
compression and communication of images and sound. Its research
activities are concentrated in the following areas:
computer vision and image processing,
graphics, and animation and virtual reality.
More recently, the group has begun to develop close links with the
extensive network of media production companies in the Bristol area
with a view to conducting inter-disciplinary research in digital media
technology and creative media content production. This work forms part
of the Creative Media Technology Initiative in which the group is
a major contributor. Research in this area focuses on the
merging of video, graphics and animation technology, particularly in
relation to the development of novel techniques for generating 3-D
An EPSRC project has led to the development of a new image segmentation
method based on colour and texture which will form the basis of a number
of new projects.
A vision system, funded by a medical charity, to recognise brain tumours
in MR images is identifying tumours with less than 1% false positives.
Ongoing funding has been approved.
An EPSRC funded project in collaboration with Warwick University has
developed an advanced model-based video codec.
A database of 350 natural outdoor scenes have been carefully segmented
and hand labelled to provide a ground truth for research into object
recognition. This is a collaboration with British Aerospace who plan to
make the database available to other researchers in the field.
INSITE, a joint international project supported by the British Council,
has developed an archaeological visualisation tool. This system has
been used to reconstruct several archaeological sites, and annual
dayschools have been organised in this area.
An EPSRC project on the Dynamics of Deformable Bodies has produced a
theory and implementation to animate deformable bodies.
The Scope Rendering System supports photorealistic image generation and
includes dynamic discontinuity meshing for radiosity rendering.
