This project has the potential to benefit bionic ear and hearing aid users through the development of signal processing methods that mimic the amazing abilities of the brain. Speech perception performance by bionic ear users has reached a plateau and these new strategies could produce the breakthrough needed to provide the next increase in performance. The benefit for greater improved hearing has enormous benefit and potential for improving the quality of life of the hearing impaired, especially those with severe and profound hearing loss. In addition, the algorithms may provide more robust automatic speech recognition, making this technology more useful in everyday situations; the markets that this would open up are enormous.Read moreRead less
Adaptive learning of spatiotemporal patterns: Development of multi-layer spiking neuron networks using Hebbian and competitive learning. The aim of this project is to develop a method for recognising patterns that change in time. The development of a reliable method that is fast and robust to noise will have wide application in many areas, especially computer speech recognition where timing plays a crucial role. Building-blocks similar to those in the brain (spiking neurons) will be used.

Building-blocks similar to those in the brain (spiking neurons) will be used. Automatic techniques will be used to teach groups of spiking neurons the differences between sequences of events by adjusting connections between them. The significance of this approach is that it captures information about timing that is missed in existing techniques.Read moreRead less

Index coding for multimedia content distribution networks. The project aims to develop new bandwidth-efficient index coding schemes to reduce network congestion. A large portion of the increasing internet traffic is due to video content browsing and distribution. This creates serious strains on the current network infrastructure, which is designed to support conventional data. It is crucial to explore new avenues to reduce the network congestion due to large file downloads. The project aims to t ....Index coding for multimedia content distribution networks. The project aims to develop new bandwidth-efficient index coding schemes to reduce network congestion. A large portion of the increasing internet traffic is due to video content browsing and distribution. This creates serious strains on the current network infrastructure, which is designed to support conventional data. It is crucial to explore new avenues to reduce the network congestion due to large file downloads. The project aims to tackle this problem by exploring new index coding techniques that are robust to failures in wireless and wired network links. Using advanced mathematical tools from algebraic number theory and module theory, the project aims to design optimally bandwidth-efficient index coding schemes that enable timely and reliable content distribution to end users.Read moreRead less

Audio, video, and still image data dominate our daily lives. Such information has commercial and strategic importance. It is invaluable in crime prevention: for example, video from security cameras. The protection of commercially valuable material against piracy and sensitive information against security breaches is vital to our economy and our safety. This project addresses these issues, by developing new, secure watermarks and fingerprints to protect digital information. Such watermarks can also protect radio communication channels, which is important due to the rising demand for wireless connectivity.Read moreRead less

Optical-OFDM provides Australia with an opportunity to develop a new, high-tech, easy-to-export technology with a very large market potential spanning three key communications markets: wireless personal-area networks, local-area networks and long-haul (80-4000 km) optical networks. It is based on innovative Australian technology generated from two research strengths: photonics and OFDM. OFDM is already the basis of most non-optical broadband systems, including digital broadcasting and ADSL. Patent applications have been filed. One application enables bandwidths to rural and remote communities to be quadrupled without laying new cables. By launching off this local market Australian industry can develop a world leading industry.Read moreRead less
Visual Tracking: Geometric Fitting and Filtering. One of the most elementary things that people and sighted animals do is to follow moving objects with their eyes. Movement is a cue to the importance and relevance of objects in a scene. Visually tracking objects allows the determination of important characteristics - distance to the object, shape of the object, likely behaviour of the object etc. Though systems have been built that can perform visual tracking: accuracy and reliability must be i ....Visual Tracking: Geometric Fitting and Filtering. One of the most elementary things that people and sighted animals do is to follow moving objects with their eyes. Movement is a cue to the importance and relevance of objects in a scene. Visually tracking objects allows the determination of important characteristics - distance to the object, shape of the object, likely behaviour of the object etc. Though systems have been built that can perform visual tracking: accuracy and reliability must be improved though a better understanding of the underlying processes. Applications include visual inspection (industrial automation), surveillance (civil and military), robot vision for scene understanding and navigation, multimedia production (automatic human motion capture for example), and human computer interfaces.
