The Challenge of Alignment Distortion and Creating Next Generation Automatic Facial Expression Detection. The last two decades have seen an escalating interest in automating the coding of facial expressions. Despite this keen interest, the promise of computer vision systems to accurately code facial expressions in natural circumstances remains elusive. Our interdisciplinary team will research a new paradigm to account for facial alignment distortion directly rather than aiming to achieve invariance to it. The project will also research new data agnostic feature compaction capabilities to enable scalable learning on the world’s largest and challenging expression dataset available to us through international collaboration. Tackling these two major open problems will make accurate coding of facial expressions in natural environments achievable.Read moreRead less

Online machine learning problems arise from situations where data is provided a point at a time. There are many classical algorithms for solving such problems based on the principle of stochastic gradient descent. Recent research by the CIs and others have thrown up interesting but diverse geometric connections that offer new insights. The proposed research aims to integrate the understanding of these algorithms with the aim of designing algorithms better able to exploit prior knowledge, and to extend existing algorithms to new problem domains thus offering well principled and well understood algorithms for solving a variety of novel online problems.Read moreRead less
Semantic Vectorisation: From Bitmaps to Intelligent Representations. The objective of this innovative project is to provide a solution to the open question of representing natural images by semantically rich vector graphics. The challenges are to identify key visual and temporal elements for images and videos, and efficiently decompose the visual data into semantic vector representations that are faithful to original data, compact and editable. The project aims to investigate new bitmap-to-vecto ....Semantic Vectorisation: From Bitmaps to Intelligent Representations. The objective of this innovative project is to provide a solution to the open question of representing natural images by semantically rich vector graphics. The challenges are to identify key visual and temporal elements for images and videos, and efficiently decompose the visual data into semantic vector representations that are faithful to original data, compact and editable. The project aims to investigate new bitmap-to-vector conversion methods. It is expected to develop a framework where semantic labels and hyperlinks can be embedded in visual data automatically. It hopes to pioneer the creation of a web of images where the links are on image/video regions. New image simplification, stylisation, and non-photorealistic rendering methods are expected to be provided.Read moreRead less

Precision Pulsar Timing and its Applications. The rapidly rotating pulsars known as millisecond pulsars have period stabilities which rival that of the best terrestrial clocks. Observations of many millisecond pulsars spread across the sky should allow detection of the gravitational-wave background - likely to be the first direct detection of gravity waves. It will also enable establishment of a long-term time standard which is independent of and probably superior to that derived from terrestria ....Precision Pulsar Timing and its Applications.

Investigation and application of techniques for overcoming radio interference will be an important part of the project.Read moreRead less
Defeating Radio Frequency Interference. The radio spectrum is a valuable resource. Development of techniques which minimize the impact of various users on one another, allowing this resource to be shared, will benefit the entire community. For astronomy in particular, shared use is essential because of the very wide bandwidths needed to obtain sufficient sensitivity. Usage of the radio spectrum is increasing rapidly and radio telescopes are becoming more and more sensitive, compounding the probl ....Defeating Radio Frequency Interference. The radio spectrum is a valuable resource. Development of techniques which minimize the impact of various users on one another, allowing this resource to be shared, will benefit the entire community. For astronomy in particular, shared use is essential because of the very wide bandwidths needed to obtain sufficient sensitivity. Usage of the radio spectrum is increasing rapidly and radio telescopes are becoming more and more sensitive, compounding the problems. The digital signal processing techniques developed under this project will be widely applicable, not only to future radio astronomy facilities such as the Square Kilometer Array, but also to the communications industry generally.Read moreRead less
Design of Multi-Gigabit Millimeter Wave Cellular Networks. It has been predicted that within the next ten years trillions of devices will connect to cellular networks and cause a thousand-fold increase in mobile traffic. This will lead to a severe spectrum shortage and congested cellular networks.

This will lead to a severe spectrum shortage and congested cellular networks. Large expanses of the millimetre-wave spectrum have the potential to meet the capacity demands of future cellular networks. The project aims to develop the fundamental sciences for millimetre-wave cellular communications, which thought to be essential for the design of next generation cellular networks with data rates at least three orders of magnitude faster than those in current cellular networks. The research outcomes are expected to provide the foundations and tools for building a future mobile broadband network infrastructure in Australia.Read moreRead less
