Current projects

Effective image search and retrieval through automatic image annotation

(2015, $270K)

The project is funded from the ARC Discovery Project Scheme (2013 – 2015). The aim of the project is to develop an efficient and effective semantic based image retrieval system that will automatically annotate images and allow images to be searched in much the same way as we search text documents currently.

Multiview video coding using cuboid data compression

(2013-2015, $315K)

This project investigates novel approaches to multiview video coding that use new data compression techniques and explicit occlusion handling. These new approaches complement the state-of-the-art, improving interactivity with instantaneous view change and VCR functionality, reducing encoding complexity, and increasing compression efficiency.

Building change detection and map update using multispectral imagery and height data

(2015, $375K)

This project will produce an effective building change detection procedure and a digital building map. Automatic building detection assists in taking possible precautions during natural disasters, whilst automatic building change detection facilitates an effective and efficient management of affected areas during and after the calamity.

Solar bio-fuel and carbon sequestration with cyanobacteria: role of genetic networks

(2014, $625K)

Bio-fuel production and carbon sequestration have been getting increasing attention in the recent years due to the dwindling fossil fuel reserves and global warming, respectively. Cyanobacteria, also known as blue-green algae, due to their naturally occurring biosynthetic machinery have a great potential in energy, carbon sequestration, oxygen production, and nitrogen cycle. Apart from being responsible for naturally sequestering a large part of carbon dioxide from the earth's atmosphere, cyanobacteria can play a key role in the harvesting of solar energy to create biomass and biofuel. An emerging idea is to sequester CO2 at source by using cyanobacteria ponds.

Improving management decisions in mental health care through applications of advanced simulation modelling

(2011-2014, $434K)

Evidence to inform management decisions about the best way to structure mental health care services is currently lacking. This project will develop a simulation modelling tool that will allow managers to explore various service configurations in virtual reality, enabling predictions to be made about the cost and quality of care.

Adaptive anomaly detection using isolation forest

(2010-onging, US$150K)

Past projects

Low-complexity video coding for wireless multimedia sensor networks

(2012, $185K)

This project developed frontier technologies to capture and transmit videos by miniaturised sensing devices. It improved Australia's telemetric surveillance capabilities and benefit defence, law enforcement, traffic control, and wildlife inhabitant monitoring agencies.

Automatic music feature extraction, classification and annotation

(2009-2011, $250K)

A huge amount of music is now available on the internet and digital devices. For example, an iPod with 60 GB storage can be purchased at a reasonable price and can store a personal music collection of many thousand music pieces. Online stores such as mp3.com provide customers with the opportunity to select and buy music from a very large range.

Computer models of genetic networks of cyanobacteria for carbon sequestration and solar bio-fuel

(2010-2012, $326K)

Bio-fuel production and carbon sequestration have received increasing attention in recent years due to dwindling fossil fuel reserves and global warming. An emerging idea is to sequester CO2 at source by using cyanobacteria ponds. Many of the cyanobacteria (commonly called the blue green algae), due to their naturally occurring biosynthetic machinery, are capable of converting CO2 to fine chemicals and fuel.

Extending supervisory and educational capacity: Web-based supervision, clinical teaching visits and workshop attendance in rural GenCOREl practice training

(2011, A$243.7K)

This project carried out a pilot study in collaboration with Southern General Practice Training (SGPT) and funded by an Education Integration grant from the General Practice Education Training Ltd (GPET). It aimed at determining how and whether web-based technology can effectively allow 'off site' supervision and patient consultation observations in rural general practice (GP) sites to reduce travel time while still allowing the delivery of a quality educational experience to GP registrars (trainees). The project involved the installation of a network of Internet Protocol cameras at a number of GP sites in the greater Gippsland region managed by SGPT and the development of a web-based secured video conferencing tool capable of differentiating image quality in the regions-of-interest in response to bandwidth constraints in the rural telecommunication networks. The study successfully carried out subjective evaluations of the experience of the participating GP registrars, their supervisors, and the patients.

Sensing and analysis system for remote monitoring of on-farm, milk storage vessels for optimal routing planning

(2013, A$64.8K)

The efficiency, product quality and on-farm safety associated with the collection of milk from individual dairy farms is heavily compromised by inadequate data provided to collecting tankers prior to pick-up. Typically, dairy parlour storage vessels are only equipped with crude dipstick devices to measure milk volume which means that collection logistics cannot be planned efficiently. Further, the quality of a milk batch can be influenced by exposure to above specification temperatures during storage - critical information required prior to collection to allow potential alternative treatment. This project seeks to address these issues in the following way:

  • Through the development and testing of a prototype system; and
  • An assessment of more sophisticated functions such as the incorporation of alarm systems and sensors for the detection of antibiotics and other milk contaminants.

A prototype system was developed and tested and the incorporation of additional, more sophisticated functions was assessed for future development projects e.g. alarm systems and sensors for detection of antibiotics and other contaminants.

Innovative multimedia applications for 3G mobile networks in remote rural Gippsland communities

(2008-2009, A$66k)

The aims of the project were to investigate the development of innovative multimedia based applications (e.g., remote health monitoring, tourism services, etc.) for 3G mobile networks to improve the condition of Gippsland local people and businesses.  In consultation with Telstra and local industries, tourism sector was chosen for such applications to boost tourism sector activities and local revenue by making information available at the fingertips of a mobile tourist in real-time.   The outcome of this project was a Masters by research project completion on 'Mobile tourist prediction'.

Other projects

Automatic music feature extraction, classification and annotation

This project was funded from 2009 to 2011 through the ARC Discovery Project Scheme. It investigated automated retrieval of music from vast digital music collections that meets the current industry need and were based not just on titles, composers and/or performers, but on the actual properties of the music itself.
