Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directiona ....Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directionality changes during accommodation (focusing). The expected outcome is improved understanding of retinal stretching changes during focusing. The benefit is that the project will lead to advancements in retinal imaging.Read moreRead less
Removing the blinkers: a wider study of the human eye. Peripheral aberrations, wide-field retinal imaging and optical parameters. This project will study peripheral (side vision) optics of the human eye and its role in the limits of visual performance. This will improve ocular measurements and contribute towards improved diagnosis and treatment of ocular diseases and short-sightedness.
Advanced methods for intraocular imaging. The ability to image the retina of the human eye at high resolution is fundamental to improving understanding of ocular physiology, ocular optics and disease diagnosis. This project applies the relatively new application of active optics to vision science. This project will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability. This project will ....Advanced methods for intraocular imaging.

This project applies the relatively new application of active optics to vision science. This project will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability. This project will achieve three-dimensional holography of human eyes and develop holography plates for correcting the aberrations of eyes. Expected outcomes are not-before experienced resolution images of the retina and better understanding of the optical characteristics of the refractive surfaces and media in the eye.Read moreRead less

Advancing Human Perception: Countering Evolving Malicious Fake Visual Data. The aim of this project is to provide new effective and generalisable deepfake detection methods for automatically detecting maliciously manipulated visual data generated by misused artificial intelligence (AI) techniques. It will present innovative computer vision and image processing knowledge and techniques, enabling the developed methods to advance human perception in recognising fake data, enhance cybersecurity, and ....Advancing Human Perception: Countering Evolving Malicious Fake Visual Data. The aim of this project is to provide new effective and generalisable deepfake detection methods for automatically detecting maliciously manipulated visual data generated by misused artificial intelligence (AI) techniques. It will present innovative computer vision and image processing knowledge and techniques, enabling the developed methods to advance human perception in recognising fake data, enhance cybersecurity, and protect privacy in AI applications. The anticipated outcomes should provide significant benefits to a wide range of applications, such as providing timely alerts to the media, government organisations, and the industry about misleading fake visual data, and preventing financial crimes on synthetic identity fraud.Read moreRead less
Estimating And Alleviating The Impacts Of Age-Related Sensory Decline

Funding Amount
$323,767.00
Summary
Sensory loss and dementia disproportionately affect older adults, often co-occur, and are the two leading contributors to disability burden among older Australians. This research will investigate the consequences that hearing and vision loss have for older adult health and wellbeing, informing strategies to reduce the disability burden of age-related sensory loss. These impacts include cognitive decline and dementia, mental health, quality of life, disability and independent living.
Cross-comparison, Validation And Performance Of Computerised Neuropsychological Assessment Devices In The Evaluation Of Mild Cognitive Impairment And Dementia
Funder
National Health and Medical Research Council
Funding Amount
$700,482.00
Summary
With an ageing population and associated increase in dementia there will be increased demand for neuropsychological assessment, with insufficient trained personnel and resources to meet this demand. Computerised tests offer excellent opportunities for large scale implementation of cognitive screening and monitoring of older adults. This is the first study to systematically evaluate and compare several popular computerised neuropsychological assessment devices in elders with and without dementia.
Predicting Language Skills From Early Auditory Speech Discrimination In Infants With Hearing Loss: Implications For Early Management And Intervention
Funder
National Health and Medical Research Council
Funding Amount
$706,113.00
Summary
Now that newborn hearing checks are available, hearing loss can be picked up soon after birth and hearing aids are fitted shortly after. Although procedures exist for checking that the devices make sounds audible, there is no way to evaluate their effectiveness for supporting a child’s auditory discrimination. This study aims to 1) develop new clinical tools for assessing infants’ auditory discrimination, and 2) determine whether early discrimination predicts spoken language at 3 years of age.
Moving Behavioural Neuroscience & Neuroeconomics Into Dementia Prevention: Spatial Tracking And Economic Decision-making As New Sensitive Measures Of Daily Function
Funder

Funding Amount
$595,588.00
Summary
This project will aim to develop new measures for clinical trials by learning the relationship between older people's movements around the house, ability to make decisions about their health and finance and their cognitive performance. These instruments may aid future trials of drugs and other interventions for preventing dementia by indicating how basic behavioural patterns respond to interventions.
Early Indicators Of Noise Injury: Are Decreased Auditory Processing Skills Evident In Noise-exposed Adults Prior To Diagnosis Of Hearing Loss?
Funder
National Health and Medical Research Council
Funding Amount
$367,605.00
Summary
Recent research indicates that noise-exposed individuals with similar hearing thresholds to non-noise exposed counterparts are more likely to have diminished temporal and spectral auditory processing abilities. This research aims to determine the relationship between noise exposure levels and auditory processing difficulties; the influence of musical training in ameliorating these difficulties; and a neurological model of causation, operation and possible remediation of these difficulties.
