Research
The Centre’s current areas of investigation are as follows:
Computer Vision Group, DSTO
The statistical analysis of video based on an understanding of
the imaging geometry has facilitated the development of a number of
techniques now commonly used in the digital media industries. The
most notable example of this is the point tracking and bundle adjustment
processes now commonly used in the process of embedding CG characters
in live video. This project aims to apply this technology to
develop the next generation of tools, and to develop tools for other
industry sectors.
The group's work on interactive 3D modelling from video falls within this area. This work has led to a number of publications, including that covering VideoTrace at Siggraph '07.
This project builds on recent research collaboration with Coastwatch and
DSTO.
Computer vision Group, High Performance Computing Group
The Visual Surveillance Project researches surveillance of video
image streams for security purposes. This includes the automated detection
of sensitive objects; reduction of false positive detections; tracking
of entities through multiple cameras; construction of video repositories,
intelligent searching through video repositories for recorded events
of interest; and cooperative utilisation of networks of cameras.
A significant commercial research project has recently been completed by the
Video Surveillance and Analysis Group for a major commercial imaging technology provider. This interaction builds on a strong history of collaborative research between the researchers involved, and particularly on the success of the group as members of teh CRC for Sensor Siglan and Information Processing before its funding cycle ended.
Interactive Simulation and Visualisation
School of Architecture, SAPAC,
High Performance Computing Group, Skymatrix Pty Ltd
The benefits of simulation and visualisation are becoming apparent
across a range of industries. The use of games in education,
for instance, is a growth area within military, medical, and occupational
health and safety programs. The virtual reality facilities of the
Australian School of Petroleum and of the South Australian Partnership
for Advanced Computing form a key component of this research program.
The air warfare destroyer contract offers a number of opportunities
for collaborative research in simulation and visualisation. These
avenues will be explored in negotiations with ASC Shipbuilder and
DSTO.
Three-dimensional data processing
iSite3D, Maptek, Computer Vision Group
Laser range finders are capable of generating a detailed and accurate
depth map of a scene in a short period of time. The data generated
are, however, unsuitable for many applications because they consist
only of a series of point samples. Processing these depth maps
to estimate a surface mesh, to fill in holes, and to join multiple
reconstructions are crucial research problems.
iSite3D and Maptek have shown great enthusiasm for the concept
of a Centre for Visual Technologies and Digital Design, both in terms
of the education program, and the opportunity it provides for developing
linkages between industry and the University. Interest has particularly
been shown in creating a research group investigating the next generation
of laser range finder applications.
