Precision single-camera eye tracking towards cognitive health assessment (2024)
Presentation / Conference Contribution

Eye tracking has been increasingly recognised as a valuable
tool for assessing cognitive health. However, many existing eye tracking systems are often expensive, imprecise, and inconvenient, which limits their accessibility and effectiveness in clin... Read More about Precision single-camera eye tracking towards cognitive health assessment.

SPGNet: A shape-prior guided network for medical image segmentation (2024)
Presentation / Conference Contribution

Given the intricacy and variability of anatomical structures in medical images, some methods employ shape priors to constrain segmentation. However, limited by the representational capability of these priors, existing approaches often struggle to cap... Read More about SPGNet: A shape-prior guided network for medical image segmentation.

A robust machine learning framework for diabetes prediction (2021)
Presentation / Conference Contribution

Diabetes mellitus is a metabolic disorder characterized by hyperglycemia which results from the inadequacy of the body to secret and responds to insulin. If not properly managed or diagnosed on time, diabetes can pose a risk to vital body organs such... Read More about A robust machine learning framework for diabetes prediction.

Contactless robust 3D palm-print identification using photometric stereo (2021)
Presentation / Conference Contribution

Palmprints are of considerable interest as a reliable biometric, since they offer significant advantages, such as greater user acceptance than fingerprint or iris recognition. 2D systems can be spoofed by a photograph of a hand; however, 3D avoids th...

Broad-leaf weed detection in pasture (2018)
Presentation / Conference Contribution

Weed control in pasture is a challenging problem that can be expensive and environmentally unfriendly. This paper proposes a novel method for recognition of broad-leaf weeds in pasture such that precision weed control can be achieved with reduced her...

Multispectral contactless 3D handprint acquisition for identification (2018)
Presentation / Conference Contribution

We present and experimentally demonstrate the potential effectiveness of a photometric stereo based high resolution system for capturing 3D handprints using visible light sources. The sub-surface vascular structures are also enhanced through the use... Read More about Multispectral contactless 3D handprint acquisition for identification.

2D and 3D face analysis for ticketless rail travel (2018)
Presentation / Conference Contribution

Research is reported into the design, implementation and functionalities of a vision system that employs the human face as a biometric for enabling ticketless rail travel. The system has been developed to optimise performance in the relatively unstru... Read More about 2D and 3D face analysis for ticketless rail travel.

Teaching machines to ask questions (2018)
Presentation / Conference Contribution

We propose a novel neural network model that aims to generate diverse and human-like natural language questions. Our model not only directly captures the variability in possible questions by using a latent variable, but also generates certain types o... Read More about Teaching machines to ask questions.

Recognizing surgically altered faces using local edge gradient Gabor magnitude pattern (2017)
Presentation / Conference Contribution

For humans, every face is unique and can be recognized amongst similar faces. This is yet to be so for machines. Our assumption is that beneath the uncertain primitive visual features of face images are intrinsic structural patterns that uniquely dis...

Two-source surface reconstruction using polarisation (2017)
Presentation / Conference Contribution

© Springer International Publishing AG 2017. Polarisation vision aims to capture and interpret the polarisation state of incoming light as part of a computer vision system. In this paper, polarisation information is fused with two-source photometric... Read More about Two-source surface reconstruction using polarisation.

Locomotion traits of dairy cows from overhead three-dimensional video (2016)
Presentation / Conference Contribution

We investigate two locomotion traits in dairy cows from overhead 3D video to observe lameness trends. Detecting lameness -particularly at an early stage- is important in order to allow early treatment which maximizes detection benefits. The proposed...

Overhead spine arch analysis of dairy cows from three-dimensional video (2016)
Presentation / Conference Contribution

We present a spine arch analysis method in dairy cows using overhead 3D video data. This method is aimed for early stage lameness detection. That is important in order to allow early treatment; and thus, reduce the animal suffering and minimize the h...

Quadruped locomotion analysis using three-dimensional video (2016)
Presentation / Conference Contribution

Abstract— To date, there has not been a single method
suitable for large-scale or regular-basis implementation to analyze the locomotion of quadruped animals. Existing methods are not sensitive enough for detecting minor deviations from healthy gait... Read More about Quadruped locomotion analysis using three-dimensional video.

Non-intrusive automated measurement of dairy cow body condition using 3D video (2015)
Presentation / Conference Contribution

Regular scoring of a dairy herd in terms of various physical metrics such as Body Condition Score (BCS), mobility and weight are essential for maintaining high animal welfare. This paper presents preliminary results of an automated system capable of... Read More about Non-intrusive automated measurement of dairy cow body condition using 3D video.

Hierarchical rank-based veiling light estimation for underwater dehazing (2015)
Presentation / Conference Contribution

Current dehazing approaches are often hindered when scenes contain bright objects which can cause veiling light and transmission estimation methods to fail. This paper introduces a single image dehazing approach for underwater images with novel veili... Read More about Hierarchical rank-based veiling light estimation for underwater dehazing.

Testing the validity of Lambert's law for micro-scale photometric stereo applied to paper substrates (2015)
