Rishi Ramakrishnan Doctor of Philosophy The University of Sydney September 2015 Illumination Invariant Outdoor Perception This thesis proposes the use of a multi-modal sensor approach to achieve illumination invariance in images taken in outdoor environments. The approach is automatic in that it does not require user input for initialisation, and is not reliant on the input of atmospheric radia...

INTRODUCTION Alcohol is the leading cause of death and disability globally among males aged 15–24 in all regions except the Eastern Mediterranean and females aged 15–24 in the wealthy nations and the Americas; much of this burden is from injury. Excessive alcohol use is the leading drug problem among young people in the USA, and the leading causes of alcohol-related deaths among young people in...

We show how high-level scene properties can be inferred from classiication of low-level image features, speciically for the indoor-outdoor scene retrieval problem. We systematically studied the features: (1) his-tograms in the Ohta color space (2) multiresolution, simultaneous autoregressive model parameters (3) coef-cients of a shift-invariant DCT. We demonstrate that performance is improved b...

BACKGROUND Agaricus brasiliensis (A. brasiliensis) is a medicinal mushroom that exerts various pharmacological actions. We previously demonstrated that different cultivation conditions altered the activity of the polyphenol-related enzymes from this mushroom. However, the influence of cultivation conditions on the antioxidant activity of the fruiting bodies remains unclear. Therefore, in this s...

PURPOSE The hypothesis that outdoor exposure might protect against myopia has generated much interest, although available data find only modest clinical efficacy. We tested the effect of outdoor rearing on form-deprivation myopia in chicks, a myopia model markedly inhibited by high-intensity indoor laboratory lighting. METHODS Unilaterally goggled cohorts of White Leghorn chicks were maintain...

BACKGROUND Despite an increasing preference of consumers for beef produced from more extensive pasture-based production systems and potential human health benefits from the consumption of such beef, data regarding the health status of animals raised on pasture are limited. The objective of this study was to characterise specific aspects of the bovine peripheral and the gastrointestinal muscosal...

This paper presents a framework to perform outdoor photometric stereo by utilizing environment light. We present the main considerations in designing the framework and steps of the processing pipeline. Our framework extends existing algorithms to meet the robustness and variability necessary to operate out of a laboratory environment. We verify our environment light photometric stereo framework...
